What Is a Research Methodology? | Steps & Tips

Published on 25 February 2019 by Shona McCombes . Revised on 10 October 2022.

Your research methodology discusses and explains the data collection and analysis methods you used in your research. A key part of your thesis, dissertation, or research paper, the methodology chapter explains what you did and how you did it, allowing readers to evaluate the reliability and validity of your research.

It should include:

• The type of research you conducted
• How you collected and analysed your data
• Any tools or materials you used in the research
• Why you chose these methods
• Your methodology section should generally be written in the past tense .
• Academic style guides in your field may provide detailed guidelines on what to include for different types of studies.
• Your citation style might provide guidelines for your methodology section (e.g., an APA Style methods section ).

Your methods section is your opportunity to share how you conducted your research and why you chose the methods you chose. It’s also the place to show that your research was rigorously conducted and can be replicated .

It gives your research legitimacy and situates it within your field, and also gives your readers a place to refer to if they have any questions or critiques in other sections.

You can start by introducing your overall approach to your research. You have two options here.

Option 1: Start with your “what”

What research problem or question did you investigate?

• Aim to describe the characteristics of something?
• Explore an under-researched topic?
• Establish a causal relationship?

And what type of data did you need to achieve this aim?

• Quantitative data , qualitative data , or a mix of both?
• Primary data collected yourself, or secondary data collected by someone else?
• Experimental data gathered by controlling and manipulating variables, or descriptive data gathered via observations?

Option 2: Start with your “why”

Depending on your discipline, you can also start with a discussion of the rationale and assumptions underpinning your methodology. In other words, why did you choose these methods for your study?

• Why is this the best way to answer your research question?
• Is this a standard methodology in your field, or does it require justification?
• Were there any ethical considerations involved in your choices?
• What are the criteria for validity and reliability in this type of research ?

Once you have introduced your reader to your methodological approach, you should share full details about your data collection methods .

Quantitative methods

In order to be considered generalisable, you should describe quantitative research methods in enough detail for another researcher to replicate your study.

Here, explain how you operationalised your concepts and measured your variables. Discuss your sampling method or inclusion/exclusion criteria, as well as any tools, procedures, and materials you used to gather your data.

Surveys Describe where, when, and how the survey was conducted.

• How did you design the questionnaire?
• What form did your questions take (e.g., multiple choice, Likert scale )?
• Were your surveys conducted in-person or virtually?
• What sampling method did you use to select participants?
• What was your sample size and response rate?

Experiments Share full details of the tools, techniques, and procedures you used to conduct your experiment.

• How did you design the experiment ?
• How did you recruit participants?
• How did you manipulate and measure the variables ?
• What tools did you use?

Existing data Explain how you gathered and selected the material (such as datasets or archival data) that you used in your analysis.

• Where did you source the material?
• How was the data originally produced?
• What criteria did you use to select material (e.g., date range)?

The survey consisted of 5 multiple-choice questions and 10 questions measured on a 7-point Likert scale.

The goal was to collect survey responses from 350 customers visiting the fitness apparel company’s brick-and-mortar location in Boston on 4–8 July 2022, between 11:00 and 15:00.

Here, a customer was defined as a person who had purchased a product from the company on the day they took the survey. Participants were given 5 minutes to fill in the survey anonymously. In total, 408 customers responded, but not all surveys were fully completed. Due to this, 371 survey results were included in the analysis.

Qualitative methods

In qualitative research , methods are often more flexible and subjective. For this reason, it’s crucial to robustly explain the methodology choices you made.

Be sure to discuss the criteria you used to select your data, the context in which your research was conducted, and the role you played in collecting your data (e.g., were you an active participant, or a passive observer?)

Interviews or focus groups Describe where, when, and how the interviews were conducted.

• How did you find and select participants?
• How many participants took part?
• What form did the interviews take ( structured , semi-structured , or unstructured )?
• How long were the interviews?
• How were they recorded?

Participant observation Describe where, when, and how you conducted the observation or ethnography .

• What group or community did you observe? How long did you spend there?
• How did you gain access to this group? What role did you play in the community?
• How long did you spend conducting the research? Where was it located?
• How did you record your data (e.g., audiovisual recordings, note-taking)?

Existing data Explain how you selected case study materials for your analysis.

• What type of materials did you analyse?
• How did you select them?

In order to gain better insight into possibilities for future improvement of the fitness shop’s product range, semi-structured interviews were conducted with 8 returning customers.

Here, a returning customer was defined as someone who usually bought products at least twice a week from the store.

Surveys were used to select participants. Interviews were conducted in a small office next to the cash register and lasted approximately 20 minutes each. Answers were recorded by note-taking, and seven interviews were also filmed with consent. One interviewee preferred not to be filmed.

Mixed methods

Mixed methods research combines quantitative and qualitative approaches. If a standalone quantitative or qualitative study is insufficient to answer your research question, mixed methods may be a good fit for you.

Mixed methods are less common than standalone analyses, largely because they require a great deal of effort to pull off successfully. If you choose to pursue mixed methods, it’s especially important to robustly justify your methods here.

Next, you should indicate how you processed and analysed your data. Avoid going into too much detail: you should not start introducing or discussing any of your results at this stage.

In quantitative research , your analysis will be based on numbers. In your methods section, you can include:

• How you prepared the data before analysing it (e.g., checking for missing data , removing outliers , transforming variables)
• Which software you used (e.g., SPSS, Stata or R)
• Which statistical tests you used (e.g., two-tailed t test , simple linear regression )

In qualitative research, your analysis will be based on language, images, and observations (often involving some form of textual analysis ).

Specific methods might include:

• Content analysis : Categorising and discussing the meaning of words, phrases and sentences
• Thematic analysis : Coding and closely examining the data to identify broad themes and patterns
• Discourse analysis : Studying communication and meaning in relation to their social context

Mixed methods combine the above two research methods, integrating both qualitative and quantitative approaches into one coherent analytical process.

Above all, your methodology section should clearly make the case for why you chose the methods you did. This is especially true if you did not take the most standard approach to your topic. In this case, discuss why other methods were not suitable for your objectives, and show how this approach contributes new knowledge or understanding.

In any case, it should be overwhelmingly clear to your reader that you set yourself up for success in terms of your methodology’s design. Show how your methods should lead to results that are valid and reliable, while leaving the analysis of the meaning, importance, and relevance of your results for your discussion section .

• Quantitative: Lab-based experiments cannot always accurately simulate real-life situations and behaviours, but they are effective for testing causal relationships between variables .
• Qualitative: Unstructured interviews usually produce results that cannot be generalised beyond the sample group , but they provide a more in-depth understanding of participants’ perceptions, motivations, and emotions.
• Mixed methods: Despite issues systematically comparing differing types of data, a solely quantitative study would not sufficiently incorporate the lived experience of each participant, while a solely qualitative study would be insufficiently generalisable.

Remember that your aim is not just to describe your methods, but to show how and why you applied them. Again, it’s critical to demonstrate that your research was rigorously conducted and can be replicated.

1. Focus on your objectives and research questions

The methodology section should clearly show why your methods suit your objectives  and convince the reader that you chose the best possible approach to answering your problem statement and research questions .

2. Cite relevant sources

Your methodology can be strengthened by referencing existing research in your field. This can help you to:

• Show that you followed established practice for your type of research
• Discuss how you decided on your approach by evaluating existing research
• Present a novel methodological approach to address a gap in the literature

3. Write for your audience

Consider how much information you need to give, and avoid getting too lengthy. If you are using methods that are standard for your discipline, you probably don’t need to give a lot of background or justification.

Regardless, your methodology should be a clear, well-structured text that makes an argument for your approach, not just a list of technical details and procedures.

Methodology refers to the overarching strategy and rationale of your research. Developing your methodology involves studying the research methods used in your field and the theories or principles that underpin them, in order to choose the approach that best matches your objectives.

Methods are the specific tools and procedures you use to collect and analyse data (e.g. interviews, experiments , surveys , statistical tests ).

In a dissertation or scientific paper, the methodology chapter or methods section comes after the introduction and before the results , discussion and conclusion .

Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.

A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research.

For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.

Statistical sampling allows you to test a hypothesis about the characteristics of a population. There are various sampling methods you can use to ensure that your sample is representative of the population as a whole.

Overview of writing the literature review

Conducting a literature review enables you to demonstrate your understanding and knowledge of the existing work within your field of research. Doing so allows you to identify any underdeveloped areas or unexplored issues within a specific debate, dialogue or field of study. This, in turn, helps you to clearly and persuasively demonstrate how your own research will address one or more of these gaps.

Disciplinary differences

Please note: this guide is not specific to any one discipline. The literature review can vary depending on the nature of the research and the expectations of the school or department. Please adapt the following advice to meet the demands of your dissertation and the expectations of your school or department. Consult your supervisor for further guidance; you can also check out  Writing Across Subjects guide .

Guide contents

As part of the Writing the Dissertation series, this guide covers the most common expectations for the literature review chapter, giving you the necessary knowledge, tips and guidance needed to impress your markers!  The sections are organised as follows:

What is the literature review?

The literature review of a dissertation gives a clear, critical overview of a specific area of research. Our main Writing the Dissertation - Overview and Planning guide explains how you can refine your dissertation topic  and begin your initial research; the next tab of this guide, 'Process', expands on those ideas. In summary, the process of conducting a literature review usually involves the following:

• Conducting a series of strategic searches to identify the key texts within that topic.
• Identifying the main argument in each source, the relevant themes and issues presented and how they relate to each other.
• Critically evaluating your chosen sources and determining their strengths, weaknesses, relevance and value to your research along with their overall contribution to the broader research field.
• Identifying any gaps or flaws in the literature which your research can address.

Literature review as both process and product

Writers should keep in mind that the phrase 'literature review' refers to two related, but distinct, things:

• 'Literature review' refers, first, to the  active process  of discovering and assessing relevant literature.
• 'Literature review' refers, second, to the  written product  that emerges from the above process.

This distinction is vital to note because  every  dissertation requires the writer to engage with and consider existing literature (i.e., to undertake the active  process ). Research doesn't exist in a void, and it's crucial to consider how our work builds from or develops existing foundations of thought or discovery. Thus, even if your discipline doesn't require you to include a chapter titled 'Literature Review' in your submitted dissertation, you should expect to engage with the process of reviewing literature.

Why is it important to be aware of existing literature?

• You are expected to explain how your research fits in with other research in your field and, perhaps, within the wider academic community.
• You will be expected to contribute something new, or slightly different, so you need to know what has already been done.
• Assessing the existing literature on your topic helps you to identify any gaps or flaws within the research field. This, in turn, helps to stimulate new ideas, such as addressing any gaps in knowledge, or reinforcing an existing theory or argument through new and focused research.

Not all literature reviews are the same. For example, in many subject areas, you are expected to include the literature review as its own chapter in your dissertation. However, in other subjects, the dissertation structure doesn't include a dedicated literature review chapter; any literature the writer has reviewed is instead incorporated in other relevant sections such as the introduction, methodology or discussion.

For this reason, there are a number of questions you should discuss with your supervisor before starting your literature review. These questions are also great to discuss with peers in your degree programme. These are outlined in the table below (see the Word document for a copy you can save and edit):

• Dissertation literature review planning table

Literature review: the process

Conducting a literature review requires you to stay organised and bring a systematic approach to your thinking and reading. Scroll to continue reading, or click a link below to jump immediately to that section:

Choosing a topic

The first step of any research project is to select an interesting topic. From here, the research phase for your literature review helps to narrow down your focus to a particular strand of research and to a specific research question. This process of narrowing and refining your research topic is particularly important because it helps you to maintain your focus and manage your material without becoming overwhelmed by sources and ideas.

Try to choose something that hasn’t been researched to death. This way, you stand a better chance of making a novel contribution to the research field.

Conversely, you should avoid undertaking an area of research where little to no work has been done. There are two reasons for this:

• Firstly, there may be a good reason for the lack of research on a topic (e.g. is the research useful or worthwhile pursuing?).
• Secondly, some research projects, particularly practice-based ones involving primary research, can be too ambitious in terms of their scope and the availability of resources. Aim to contribute to a topic, not invent one!

Searching for sources

Researching and writing a literature review is partly about demonstrating your independent research skills. Your supervisor may have some tips relating to your discipline and research topic, but you should be proactive in finding a range of relevant sources. There are various ways of tracking down the literature relevant to your project, as outlined below.

Make use of Library Search

One thing you don’t want to do is simply type your topic into Google and see what comes up. Instead, use Library Search to search the Library’s catalogue of books, media and articles.

Online training for 'Using databases' and 'Finding information' can be found here . You can also use the Library's subject pages to discover databases and resources specific to your academic discipline.

Engage with others working in your area

As well as making use of library resources, it can be helpful to discuss your work with students or academics working in similar areas. Think about attending relevant conferences and/or workshops which can help to stimulate ideas and allows you to keep track of the most current trends in your research field.

Look at the literature your sources reference

Finding relevant literature can, at times, be a long and slightly frustrating experience. However, one good source can often make all the difference. When you find a good source that is both relevant and valuable to your research, look at the material it cites throughout and follow up any sources that are useful. Also check if your source has been cited in any more recent publications.

Think of the bibliography/references page of a good source as a series of breadcrumbs that you can follow to find even more great material.

Evaluating sources

It is very important to be selective when choosing the final sources to include in your literature review. Below are some of the key questions to ask yourself:

• If a source is tangentially interesting but hasn’t made any particular contribution to your topic, it probably shouldn’t be included in your literature review. You need to be able to demonstrate how it fits in with the other sources under consideration, and how it has helped shape the current state of the literature.
• There might be a wealth of material available on your chosen subject, but you need to make sure that the sources you use are appropriate for your assignment. The safest approach to take is to use only academic work from respected publishers. However, on occasions, you might need to deviate from traditional academic literature in order to find the information you need. In many cases, the problem is not so much the sources you use, but how you use them. Where relevant, information from newspapers, websites and even blogs are often acceptable, but you should be careful how you use that information. Do not necessarily take any information as factual. Instead be critical and interpret the material in the context of your research. Consider who the writer is and how this might influence the authority and reliability of the information presented. Consult your supervisor for more specific guidance relating to your research.
• The mere fact that something has been published does not automatically guarantee its quality, even if it comes from a reputable publisher. You will need to critique the content of the source. Has the author been thorough and consistent in their methodology? Do they present their thesis coherently? Most importantly, have they made a genuine contribution to the topic?

Keeping track of your sources

Once you have selected a source to use in your literature review, it is useful to make notes on all of its key features, including where it comes from, what it says, and what its main strengths and weaknesses are. This way you can easily re-familiarise yourself with a source without having to re-read it. Keeping an annotated bibliography is one way to do this.

Alternately, below is a table you can copy and fill out for each source (see the Word document to save an editable copy for yourself). Software such as EndNote also allows you to keep an electronic record of references and your comments on them.

• Source evaluation table

Writing your literature review

As we explored in the 'Getting Started' tab, the literature review is both a process you follow and (in most cases) a written chapter you produce. Thus, having engaged the review process, you now need to do the writing itself. Please continue reading, or click a heading below to jump immediately to that section.

Guiding principles

The structure of the final piece will depend on the discipline within which you are working as well as the nature of your particular research project. However, here are a few general pieces of advice for writing a successful literature review:

• Show the connections between your sources. Remember that your review should be more than merely a list of sources with brief descriptions under each one. You are constructing a narrative. Show clearly how each text has contributed to the current state of the literature, drawing connections between them.
• Engage critically with your sources. This means not simply describing what they say. You should be evaluating their content: do they make sound arguments? Are there any flaws in the methodology? Are there any relevant themes or issues they have failed to address? You can also compare their relative strengths and weaknesses.
• Signpost throughout to ensure your reader can follow your narrative.  Keep relating the discussion back to your specific research topic.
• Make a clear argument. Keep in mind that this is a chance to present your take on a topic. Your literature review showcases your own informed interpretation of a specific area of research. If you have followed the advice given in this guide you will have been careful and selective in choosing your sources. You are in control of how you present them to your reader.

There are several different ways to structure the literature review chapter of your dissertation. Two of the most common strategies are thematic structure and chronological structure (the two of which can also be combined ). However you structure the literature review, this section of the dissertation normally culminates in identifying the research gap.

Thematic structure

Variations of this structure are followed in most literature reviews. In a thematic structure , you organise the literature into groupings by theme (i.e., subtopic or focus). You then arrange the groupings in the most logical order, starting with the broadest (or most general) and moving to the narrowest (or most specific).

The funnel or inverted pyramid

To plan a thematic structure structure, it helps to imagine your themes moving down a funnel or inverted pyramid  from broad to narrow. Consider the example depicted below, which responds to this research question:

What role did the iron rivets play in the sinking of the Titanic?

The topic of maritime disasters is the broadest theme, so it sits at the broad top of the funnel. The writer can establish some context about maritime disasters, generally, before narrowing to the Titanic, specifically. Next, the writer can narrow the discussion of the Titanic to the ship's structural integrity, specifically. Finally, the writer can narrow the discussion of structural integrity to the iron rivets, specifically. And voila: there's the research gap!

The broad-to-narrow structure is intuitive for readers. Thus, it is crucial to consider how your themes 'nest inside' one another, from the broad to the narrow. Picturing your themes as nesting dolls is another way to envision this literature review structure, as you can see in the image below.

As with the funnel, remember that the first layer (or in this case, doll) is largest because it represents the broadest theme. In terms of word count and depth, the tinier dolls will warrant more attention because they are most closely related to the research gap or question(s).

The multi-funnel variation

The example above demonstrates a research project for which one major heading might suffice, in terms of outlining the literature review. However, the themes you identify for your dissertation might not relate to one another in such a linear fashion. If this is the case, you can adapt the funnel approach to match the number of major subheadings you will need.

In the three slides below, for example, a structure is depicted for a project that investigates this (fictional) dissertation research question: does gender influence the efficacy of teacher-led vs. family-led learning interventions for children with ADHD? Rather than nesting all the subtopics or themes in a direct line, the themes fall into three major headings.

The first major heading explores ADHD from clinical and diagnostic perspectives, narrowing ultimately to gender:

• 1.1 ADHD intro
• 1.2 ADHD definitions
• 1.3 ADHD diagnostic criteria
• 1.4 ADHD gender differences

The second major heading explores ADHD within the classroom environment, narrowing to intervention types:

• 2.1 ADHD in educational contexts
• 2.2 Learning interventions for ADHD
• 2.2.1 Teacher-led interventions
• 2.2.2 Family-led interventions

The final major heading articulates the research gap (gender differences in efficacy of teacher-led vs. family-led interventions for ADHD) by connecting the narrowest themes of the prior two sections.

Multi-funnel literature review structure by Academic Skills Service

To create a solid thematic structure in a literature review, the key is thinking carefully and critically about your groupings of literature and how they relate to one another. In some cases, your themes will fit in a single funnel. In other cases, it will make sense to group your broad-to-narrow themes under several major headings, and then arrange those major headings in the most logical order.

Chronological structure

Some literature reviews will follow a  chronological structure . As the name suggests, a review structured chronologically will arrange sources according to their publication dates, from earliest to most recent.

This approach can work well when your priority is to demonstrate how the research field has evolved over time. For example, a chronological arrangement of articles about artificial intelligence (AI) would allow the writer to highlight how breakthroughs in AI have built upon one another in sequential order.

A chronological structure can also suit literature reviews that need to capture how perceptions or understandings have developed across a period of time (including to the present day). For example, if your dissertation involves the public perception of marijuana in the UK, it  could  make sense to arrange that discussion chronologically to demonstrate key turning points and changes of majority thought.

The chronological structure can work well in some situations, such as those described above. That being said, a purely chronological structure should be considered with caution.  Organising sources according to date alone runs the risk of creating a fragmented reading experience. It can be more difficult in a chronological structure to properly synthesize the literature. For these reasons, the chronological approach is often blended into a thematic structure, as you will read more about, below.

Combined structures

The structures of literature reviews can vary drastically, and for any given dissertation there will be many valid ways to arrange the literature.

For example, many literature reviews will  combine  the thematic and chronological approaches in different ways. A writer might match their major headings to themes or subtopics, but then arrange literature chronologically within the major themes identified. Another writer might base their major headings on chronology, but then assign thematic subheadings to each of those major headings.

When considering your options, try to imagine your reader or audience. What 'flow' will allow them to best follow the discussion you are crafting? When you are reading articles, what structural approaches do you appreciate in terms of ease and clarity?

Identifying the gap

The bulk of your literature review will explore relevant points of development and scholarly thought in your research field: in other words, 'Here is what has been done so far, thus here is where the conversation now stands'. In that way, you position your project within a wider academic discussion.

Having established that context, the literature review generally culminates in an articulation of what remains to be done: the  research gap  your project addresses. See the next tab for further explanation and examples.

Demystifying the research gap

The term research gap   is intimidating for many students, who might mistakenly believe that every single element of their research needs to be brand new and fully innovative. This isn't the case!

The gap in many projects will be rather niche or specific. You might be helping to update or re-test knowledge rather than starting from scratch. Perhaps you have repeated a study but changed one variable. Maybe you are considering a much discussed research question, but with a lesser used methodological approach.

To demonstrate the wide variety of gaps a project could address, consider the examples below. The categories used and examples included are by no means comprehensive, but they should be helpful if you are struggling to articulate the gap your literature review has identified.

***P lease note that the content of the example statements has been invented for the sake of demonstration. The example statements should not be taken as expressions of factual information.

Gaps related to population or geography

Many dissertation research questions involve the study of a specific population. Those populations can be defined by nationality, ethnicity, gender, sexuality, socioeconomic class, political beliefs, religion, health status, or other factors. Other research questions target a specific geography (e.g. a country, territory, city, or similar). Perhaps your broader research question has been pursued by many prior scholars, but few (or no) scholars have studied the question in relation to your focal population or locale: if so, that's a gap.

• Example 1:  As established above, the correlations between [ socioeconomic status ] and sustainable fashion purchases have been widely researched. However, few studies have investigated the potential relationship between [ sexual identity ] and attitudes toward sustainable fashion. Therefore...
• Example 2:  Whilst the existing literature has established a clear link between [ political beliefs ] and perceptions of socialized healthcare, the influence of [ religious belief ] is less understood, particularly in regards to [ Religion ABC ].
• Example 3:  Available evidence confirms that the widespread adoption of Technology XYZ in [ North America ] has improved manufacturing efficiency and reduced costs in the automotive sector. Using predictive AI models, the present research seeks to explore whether deployment of Technology XYZ could benefit the automotive sector of [ Europe ] in similar ways.

Gaps related to theoretical framework

The original contribution might involve examining something through a new lens.  Theoretical framework  refers, most simply, to the theory or theories a writer will use to make sense of and shape (i.e., frame ) their discussion. Perhaps your topic has been analysed in great detail through certain theoretical lenses, but you intend to frame your analysis using a theory that fewer scholars have applied to the topic: if so, that's a gap.

• Example 1:  Existing discussions of the ongoing revolution in Country XYZ frame the unrest in terms of [ theory A ] and [ theory B ]. The present research will instead analyse the situation using [ theory C ], allowing greater insight into...
• Example 2:  In the first section of this literature review, I examined the [ postmodern ], [ Marxist ], and [ pragmatist ] analyses that dominate academic discussion of The World According to Garp.  By revisiting this modern classic through the lens of [ queer theory ], I intend to...

Gaps related to methodological approach

The research gap might be defined by differences of methodology (see our Writing the Methodology guide for more). Perhaps your dissertation poses a central question that other scholars have researched, but they have applied different methods to find the answer(s): if so, that's a gap.

• Example 1:  Previous studies have relied largely upon the [ qualitative analysis of interview transcripts ] to measure the marketing efficacy of body-positive advertising campaigns. It is problematic that little quantitative data underpins present findings in this area. Therefore, I will address this research gap by [ using algorithm XYZ to quantify and analyse social-media interactions ] to determine whether...
• Example 2: Via [ quantitative and mixed-methods studies ], previous literature has explored how demographic differences influence the probability of a successful match on Dating App XYZ. By instead [ conducting a content analysis of pre-match text interactions ] on Dating App XYZ, I will...

Scarcity as a gap

Absolutes such as never  and always  rarely apply in academia, but here is an exception: in academia, a single study or analysis is  never  enough. Thus, the gap you address needn't be a literal void in the discussion. The gap could instead have to do with  replicability  or  depth/scope.  In these cases, you are adding value and contributing to the academic process by testing emerging knowledge or expanding underdeveloped discussions.

• Example:  Initial research points to the efficacy of Learning Strategy ABC in helping children with dyslexia build their reading confidence. However, as detailed earlier in this review, only four published studies have tested the intervention, and two of those studies were conducted in a laboratory. To expand our growing understanding of how Learning Strategy ABC functions in classroom environments, I will...

Elapsed time as a gap

Academia values up-to-date knowledge and findings, so another valid type of gap relates to elapsed time. Many factors that can influence or shape research findings are ever evolving: technology, popular culture, and political climates, to name just a few. Due to such changes, it's important for scholars in most fields to continually update findings. Perhaps your dissertation adds value by contributing to this process.

For example, imagine if a scholar today were to rely on a handbook of marketing principles published in 1998. As good as that research might have been in 1998, technology (namely, the internet) has advanced drastically since then. The handbook's discussion of online marketing strategies will be laughably outdated when compared to more recent literature.

• Example:  A wide array of literature has explored the ways in which perceptions of gender influence professional recruitment practices in the UK. The bulk of said literature, however, was published prior to the #MeToo movement and resultant shifts in discourse around gender, power imbalances and professional advancement. Therefore...

What to avoid

This portion of the guide will cover some common missteps you should try to avoid in writing your literature review. Scroll to continue reading, or click a heading below to jump immediately to that section.

Writing up before you have read up

Trying to write your literature review before you have conducted adequate research is a recipe for panic and frustration. The literature review, more than any other chapter in your dissertation, depends upon your critical understanding of a range of relevant literature. If you have only dipped your toe into the pool of literature (rather than diving in!), you will naturally struggle to develop this section of the writing. Focus on developing your relevant bases of knowledge before you commit too much time to drafting.

Believing you need to read everything

As established above, a literature review does require a significant amount of reading. However, you aren't expected to review  everything ever written  about your topic. Instead, aim to develop a more strategic approach to your research. A strategic approach to research looks different from one project to the next, but here are some questions to help you prioritise:

• If your field values up-to-date research and discoveries, carefully consider the 'how' and 'what' before investing time reading older sources: how will the source function in your dissertation, and what will it add to your writing?
• Try to break your research question(s) down into component parts. Then, map out where your literature review will need to provide extensive detail and where it can instead present quicker background. Allocate your research time and effort accordingly. 

Omitting dissenting views or findings

While reviewing the literature, you might discover authors who disagree with your central argument or whose own findings contradict your hypothesis. Don't omit those sources: embrace them! Remember, the literature review aims to explore the academic dialogue around your topic: disagreements or conflicting findings are often part of that dialogue, and including them in your writing will create a sense of rich, critical engagement. In fact, highlighting any disagreements amongst scholars is a great way to emphasise the relevance of, and need for, your own research.

Miscalculating the scope

As shown in the funnel structure (see 'Structure' tab for more), a literature review often starts broadly and then narrows the dialogue as it progresses, ultimately bringing the reader to the dissertation's specific research topic (e.g. the funnel's narrowest point).

Within that structure, it's common for writers to miscalculate the scope required. They might open the literature review far too broadly, dedicating disproportionate space to developing background information or general theory; alternately, they might rush into the narrowest part of the discussion, failing to develop any sense of surrounding context or background, first.

It takes trial and error to determine the appropriate scope for your literature review. To help with this...

• Imagine your literature review subtopics cascading down a stairwell,  as in the illustration below.
• Place the broadest concepts on the highest steps, then narrow down to the most specific concepts on the lowest steps: the scope 'zooms in' as you move down the stairwell.
• Now, consider which step is the most logical starting place for your readers. Do they need to start all the way at the top, or should you 'zoom in'?

The illustration above shows a stairwell diagram of a dissertation that aims to analyse Stephen King's horror novel  The Stand  through the lens of a specific feminist literary theory.

• If the literature review began on one of the bottom two steps, this would feel rushed and inadequate. The writer needs to explore and define the relevant theoretical lens before they discuss how it has been applied by other scholars.
• If the literature review began on the very top step, this would feel comically broad in terms of scope: in this writing context, the reader doesn't require a detailed account of the entire history of feminism!

The third step, therefore, represents a promising starting point: not too narrow, not too broad.

The 'islands' structure

Above all else, a literature review needs to synthesize a range of sources   in a logical fashion. In this context, to  synthesize  means to bring together, connect, weave, and/or relate. A common mistake writers make is failing to conduct such synthesis, and instead discussing each source in isolation. This leads to a disconnected structure, with each source treated like its own little 'island'. The island approach works for very few projects.

Some writers end up with this island structure because they confuse the nature of the  literature review  with the nature of an annotated bibliography . The latter is a tool you can use to analyse and keep track of individual sources, and most annotated bibliographies will indeed be arranged in a source-by-source structure. That's fine for pre-writing and notetaking, but to structure the literature review, you need to think about connections and overlaps between sources rather than considering them as stand-alone works.

If you are struggling to forge connections between your sources, break down the process into tiny steps:

• e.g. Air pollution from wood-burning stoves in homes.
• e.g.  Bryant and Dao (2022) found that X% of small particle pollution in the United Kingdom can be attributed to the use of wood-burning stoves.
• e.g.  A study by Williams (2023) reinforced those findings, indicating that small particle pollution has...
• e.g.  However, Landers (2023) cautions that factor ABC and factor XYZ may contribute equally to poor air quality, suggesting that further research...

The above exercise is  not  meant to suggest that you can only write one sentence per source: you can write more than that, of course! The exercise is simply designed to help you start synthesizing the literature rather than giving each source the island treatment.

Q: I still don't get it - what's the point of a literature review?

A: Let's boil it down to three key points...

• The literature review provides a platform for you, as a scholar, to demonstrate your understanding of how your research area has evolved. By engaging with seminal texts or the most up-to-date findings in your field, you can situate your own research within the relevant academic context(s) or conversation(s).
• The literature review allows you to identify the research gap your project addresses: in other words, what you will add to discussions in your academic field.
• Finally, the literature review justifies the reason for your research. By exploring existing literature, you can highlight the relevance and purpose of your own research.

Q: What if I don't have a gap?

A:  It's normal to struggle with identifying a research gap. This can be particularly true if you are working in a highly saturated research area, broadly speaking: for example, if you are studying the links between nutrition and diabetes, or if you are studying Shakespeare.

The 'What to Avoid' tab explained that  miscalculating the scope  is a common mistake in literature reviews. If you are struggling to identify your gap, scope might be the culprit, particularly if you are working in a saturated field. Remember that the gap is the narrowest part of the funnel, the smallest nesting doll, the lowest step: this means your contribution in that giant academic conversation will need to be quite 'zoomed in':

This is not a valid gap →  Analysing Shakespeare's sonnets.

This might be a valid gap →  Conducting an ecocritical analysis of the visual motifs of Shakespeare's final five procreation sonnets (e.g. sonnets number thirteen to seventeen).

In the above example, the revised attempt to articulate a gap 'zooms in' by identifying a particular theoretical lens (e.g. ecocriticism), a specific convention to analyse (e.g. use of visual motifs), and a narrower object (e.g. five sonnets rather than all 150+). The field of Shakespeare studies might be crowded, but there is nonetheless room to make an original contribution.

Conversely, it might be difficult to identify the gap if you are working not in a saturated field, but in a brand new or niche research area. How can you situate your work within a relevant academic conversation if it seems like the 'conversation' is just you talking to yourself?

In these cases, rather than 'zooming in', you might find it helpful to 'zoom out'. If your topic is niche, think creatively about who will be interested in your results. Who would benefit from understanding your findings? Who could potentially apply them or build upon them? Thinking of this in interdisciplinary terms is helpful for some projects.

Tip:  Venn diagrams and mind maps are great ways to explore how  your research connects to, and diverges from, the existing literature.

Q: How many references should I use in my literature review?

A:  This question is risky to answer because the variations between individual projects and disciplines make it impossible to provide a universal answer. The fact is that one dissertation might have 50 more references than another, yet the two projects could be equally rigorous and successful in fulfilling their research aims.

With that warning in mind, let's consider a 'standard' dissertation of around 10K words. In that context, referencing 30 to 40 sources in your literature review tends to work well. Again, this is  not  a universally accurate rule, but a ballpark figure for you to contemplate. If the 30 to 40 estimate seems frighteningly high to you, do remember that many sources will be used sparingly rather than being mulled over at length. Consider this example:

In British GP practices, pharmaceutical treatment is most often prescribed for Health Condition XYZ ( Carlos, 2019; Jones, 2020 ; Li, 2022 ). Lifestyle modifications, such as physical exercise or meditation practices, have only recently...

When writing critically, it's important to validate findings across studies rather than trusting only one source. Therefore, this writer has cited three recent studies that agree about the claim being made. The writer will delve into other sources at more length, but here, it makes sense to cite the literature and move quickly along.

As you search the databases and start following the relevant trails of 'research bread crumbs', you will be surprised how quickly your reference list grows.

Q: What if there isn't enough relevant literature on my topic?

A: Think creatively about the literature you are using and engaging with. A good start is panning out to consider your topic more broadly: you might not identify articles that discuss your  exact  topic, but what can you discover if you shift your focus up one level?

Imagine, for example, that Norah is researching how artificial intelligence (AI) can be used to provide dance instruction. She discovers that no one has written about this topic. Rather than panicking, she breaks down her research question into its component parts to consider what research  might  exist.

• First, dance instruction: literature on how dance has traditionally been taught (i.e., not with AI) is still relevant because it will provide background and context. To appreciate the challenges or opportunities that transition to AI instruction might bring, we need to understand the status quo. Norah might also search for articles that analyse how other technological shifts have affected dance instruction: for example, how YouTube popularized at-home dance study, or how live video services like Zoom enabled real-time interaction between dance pupils and teachers despite physical distance.
• Next, artificial intelligence used for instruction: Norah can seek out research on, and examples of, the application of AI for instructive purposes. Even if those purposes don't involve dance, such literature can contribute to illustrating the broader context around Norah's project.
• Could it be relevant to discuss the technologies used to track an actor's real-life movements and convert them into the motions of a video game character? Perhaps there are parallels!
• Could it be relevant to explore research on applications of AI in creative writing and visual art? Could be relevant since dance is also a creative field!

In summary, don't panic if you can't find research on your  exact  question or topic. Think through the broader context and parallel ideas, and you will soon find what you need.

Q: What if my discipline doesn't require a literature review chapter?

A: This is a great question. Whilst many disciplines dictate that your dissertation should include a chapter called Literature Review , not all subjects follow this convention. Those subjects will still expect you to incorporate a range of external literature, but you will nest the sources under different headings.

For example, some disciplines dictate an introductory chapter that is longer than average, and you essentially nest a miniature literature review inside the introduction, itself. Although the writing is more condensed and falls under a subheading of the introduction, the techniques and principles of writing a literature review (for example, moving from the broad to the narrow) will still prove relevant.

Some disciplines include chapters with names like Background , History , Theoretical Framework , etc. The exact functions of such chapters differ, but they have this in common: reviewing literature. You can't provide a critical background or history without synthesizing external sources. To illustrate your theoretical framework, you need to synthesize a range of literature that defines the theory or theories you intend to use.

Therefore, as stated earlier in this guide, you should be prepared to review and synthesize a range of literature regardless of your discipline. You can tailor the purpose of that synthesis to the structure and demands of writing in your subject area.

Q: Does my literature review need to include every source I plan to use in my discussion chapter?

A: The short answer is 'no' - there are some situations in which it is okay to use a source in your discussion chapter that you didn't integrate into your literature review chapter.

Imagine, for example, that your study produced a surprising result: a finding that you didn't anticipate. To make sense of that result, you might need to conduct additional research. That new research will help you explain the unexpected result in your discussion chapter.

More often, however, your discussion will  draw on, or return to, sources from your literature review. After all, the literature review is where you paint a detailed picture of the conversation surrounding your research topic. Thus, it makes sense for you to relate your own work to that conversation in the discussion.

The literature review provides you an opportunity to engage with a rich range of published work and, perhaps for the first time, critically consider how your own research fits within and responds to your academic community. This can be a very invigorating process!

At the same time, it's likely that you will be juggling more academic sources than you have ever used in a single writing project. Additionally, you will need to think strategically about the focus and scope of your work: figuring out the best structure for your literature review might require several rounds of re-drafting and significant edits.

If you are usually a 'dive in without a plan and just get drafting' kind of writer, be prepared to modify your approach if you start to feel overwhelmed. Mind mapping, organising your ideas on a marker board, or creating a bullet-pointed reverse outline can help if you start to feel lost.

Alternately, if you are usually a 'create a strict, detailed outline and stick to it at all costs' kind of writer, keep in mind that long-form writing often calls for writers to modify their plans for content and structure as their work progresses and evolves. It can help such writers to schedule periodic 'audits' of their outlines, with the aim being to assess what is still working and what else needs to be added, deleted or modified.

Here’s a final checklist for writing your literature review. Remember that not all of these points will be relevant for your literature review, so make sure you cover whatever’s appropriate for your dissertation. The asterisk (*) indicates any content that might not be relevant for your dissertation. You can save your own copy of the checklist to edit using the Word document, below.

How to Write a Dissertation Literature Review – Steps & Tips

Published by Anastasia Lois at August 12th, 2021 , Revised On October 17, 2023

From an academic standpoint, a dissertation literature review can be defined as a survey of the thesis, journal articles, books, and other academic resources on any given research title . This article provides comprehensive guidelines on how to write a dissertation literature review.

A literature review in a dissertation is of critical importance primarily because it provides insight into the key concepts, advancements, theories, and results of your research questions  or  research problem .

However, it is essential to note that; a first-class dissertation literature review focuses on summarizing the academic sources used for research and analysing, interpreting, and assessing them to determine the gaps and differences in opinions, judgments, themes, and developments.

A good literature review will further elaborate on existing knowledge concerning the research hypothesis or questions.

When do you Write a Dissertation Literature Review?

Depending on your university’s guidelines, you might be required to include a literature review in the theoretical framework or the introduction.

Or you could also be asked to develop a standalone literature review chapter that appears before  the methodology  and  the findings  chapters of the dissertation.

In either case, your primary aim will be to review the available literature and develop a link between your research and the existing literature on your chosen topic.

Sometimes, you might be designated a literature review as a separate assignment . Regardless of whether you need to write a literature review for your dissertation or as a standalone project, some general guidelines for conducting literature will remain unchanged.

Here are the steps you need to take to write the literature review for a dissertation if you cannot write the literature review.

Steps of Writing a Literature Review

1. gather, assess, and choose relevant literature.

The first seed to take when writing your dissertation or thesis is to choose a fascinating and manageable research topic . Once a topic has been selected, you can begin searching for relevant academic sources.

If you are  writing a literature review for your dissertation, one way to do this is to find academic sources relevant to your  research problem or questions.

Without fully understanding current knowledge in the chosen study area, giving the correct direction to your research aim and objectives will be hard.

On the other hand, you will be expected to guide your research by developing a central question if you are writing a literature review as an individual assignment.

A notable difference here compared to the dissertation literature review is that you must answer this central question without conducting primary research (questionnaires, surveys, interviews). You  will be expected to address the question using only the existing literature.

Use Keywords and References to Find Relevant Literature

Create a list of keywords that are relevant to the topic of research. Find journals, articles, and books using these keywords. Here are links to some recognised online academic libraries and databases;

• Inspec, (Computer science, engineering, physics, chemistry)
• EconLit, (Economics)
• Google Scholar
• Your university’s online research database

Finding relevant academic sources from “the reference list” of an article you have already found in a research database effectively discovers relevant studies.

Consider noting frequently appearing references as they are likely to be highly authentic and important publications even though they didn’t appear in the keyword search.

Journal articles or books that keep appearing with different keywords and phrases are the ones you should manually look out for.

The more times an article has been referenced, the more influential it is likely to be in any research field. Google Scholar lets users quickly determine how often a particular article has been referenced.

2. Weighing and Selecting Academic Sources

It won’t be possible for you to read every publication related to your topic. An excellent way to select academic sources for your dissertation literature review is to read the abstract , which will help you decide whether the source is supportive and relevant to your research hypothesis or research questions.

To help you select sources relevant to your study, here are some questions for you to consider before making the decision.

• What research questions has the author answered with their research work?
• What fundamental concepts have been defined by the author?
• Did the researcher use an innovative methodology or existing frameworks to define fundamental methods, models, and theories?
• What are the findings, conclusion, and recommendations in the source book or paper?
• What is the relevance between the existing literature and the academic sources you are evaluating?
• Does the source article challenge, confirm, or add to existing knowledge on the topic?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Any breakthrough studies and key theories relevant to your research topic should be recorded as you search for highly credible and authentic academic sources.

The method of your review of literature depends on your academic subject. If your research topic is in the sciences, you must find and review up-to-date academic sources.

On the other hand, you might look into old and historical literature and recent literature if your research topic is in the humanities field.

Recording Information and Referencing Sources

It is recommended that you start to write your literature review as you read articles, journals, and books. Take notes which can be later merged into the text of the literature review. Avoid plagiarism  and record all sources used along with references.

A good way of recording information is to analyse each source, summarise the key concepts or theories and compile a complete list of references in the form of an annotated bibliography.

This is a beneficial practice as it helps to remember the key points in each academic source and saves you valuable time as you start the literature review write-up.

3. Identify Key Themes and Patterns

The next step is to look for themes and patterns in the chosen sources that would enable you to establish similarities and differences between their  results and interpretations .

This exercise will help you to determine the  structure and argument for your literature review. Here are some questions that you can think of when reading and recording information;

• Are any gaps in the existing literature?
• What are the weaknesses of the current literature that should be addressed?
• Were you able to identify any landmark research work and theories that resulted in the topic’s change of direction?
• What are the similarities and disagreements between these sources? Were you able to identify any contradictions and conflicts?
• What trends and themes were you able to identify? Are there any results, methods, or theories that lost credibility over time?

4. Structure of Literature Review

There is no acclaimed  literature review structure , which means that you can choose from a range of approaches (thematic, chronological, methodological, and theoretical) when deciding on the structure of the literature review .

However, before you begin to  write the literature review , it is important to figure out the strategy that would work best for you. For long literature reviews, you might decide to use a combination of these strategies. For example, you could discuss each of the themes chronologically.

1: Theoretical

You can discuss various significant concepts, models, and theories in your literature review to form the basis of a theoretical framework . You could also combine a range of theoretical approaches to develop your theoretical framework or debate the significance of a particular theoretical framework.

2: Methodological

The methodological approach will require you to relate the findings of studies conducted in different research areas and use different research methods .

• You might discover that results from the quantitative research approach are not the same as qualitative research.
• You might split the selected academic sources based on their discipline – engineering, and sciences.

3: Thematic

You may also deploy a thematic approach, especially if you identified repeating key themes and patterns. If that is the case, you will be expected to put each aspect of the topic into different subsections within your literature review.

For example, if your research topic is “employment issues in the UK for international students,” you can divide the key themes into subsections; legal status, poor language skills, immigration policy, and economic turmoil.

4: Chronological

The most straightforward approach is to trace the development of the topic over time. However, if you choose this strategy, avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points, and critical debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

5. Writing your Literature Review 

Whether it’s a dissertation literature review or a standalone literature review assignment you have been assigned, you will be expected to divide your literature review into three larger sections – introduction, main body, and a conclusion.

What you write under these three segments will depend on the aim of your study.

Section 1 – Introduction

Here you will be required to state the objectives of the literature review clearly;

Introduction to Dissertation Literature Review Recapitulate your research problem or questions with a summary of the sources you reviewed when the literature review is for your thesis or dissertation. Consider highlighting gaps in existing knowledge and stress the suitability of your topic.

For example:

Research problem A has been debated in many recent studies.

While the topic has been explored concerning A, the B aspect has not yet been explored.

Individual Literature Review Project When reviewing literature for an individual literature review assignment, make sure that you clearly state the purpose of the research and debate the scope of the literature (how recent or old are the academic sources you are reviewing).

Section 2 – Main Body

As previously mentioned, you can divide this section into further subsections depending on your literature review’s length. You can also have a separate heading for each research method, theme, or theory to help your readers better understand your research.

Here are some tips for you to write a flawless main body of literature review;

• Summarize and Combine ; Highlight the main findings from each academic source and organise them into one whole piece without losing coherence.
• Evaluate and interpret; Make sure you are giving opinions and arguments of your own where possible. Simply rephrasing what others have said will undermine your work. You will be expected to debate and discuss other studies’ results about your research questions or aim.
• Analytical Evaluation; It is essential to unmistakably present the literature you have reviewed and the merits and weaknesses of the literature.
• Make Use of  Topic Sentences and Transitions; in organized subsections within the literature review to establish conflicts, differences, similarities, and relationships.

Example of How to Write a Dissertation Literature Review

The below example belongs to the body of a literature review on the effectiveness of e-recruitment in small and medium-sized enterprises in the United Kingdom’s IT sector.

E-recruitment means explicitly using digital technologies to recruit, select, and orient employees. The benefits of e-recruitment in the literature have been studied: increased access to a pool of candidates, time and cost savings, and greater flexibility for the organisation.

In contrast, the literature states that e-recruitment might not properly achieve the goal of retaining the workforce with the required skills to participate in the work environment (Lad & Das, 2016). Also, e-recruitment might be based on a flawed website design or poor application process, which might deter potential employees (Anand & Devi, 2016) .

This section of the study will focus on the existing studies linked to the effectiveness of e-recruitment. Human resource management is an essential function of business organisations because it manages the workforce.

The goal of HR should be to develop a strategic approach in which the organisation’s strategic goals can be attained efficiently and effectively. The advent of digital technologies has helped transform human resource management’s nature concerning recruiting and selecting employees for organisations.

The Internet’s benefits have reduced search time for candidates and significant cost savings for organisations. Finally, it offers a transparent method for obtaining information about specific candidates. E-recruitment helps organisations hire people from any part of the world as it promotes opportunities and benefits the organisation efficiently.

Sharma (2014) argues that 75% of human resource professionals in developed countries are now using e-recruitment to hire employees for their organisations. Additionally, some 2 out of 4 job seekers will use the Internet to source job opportunities.

Another evidence to support the rise of e-recruitment is a study by Holm (2014), which found that all Fortune 100 companies will be using some form of e-recruitment to advertise vacant positions.

The implications are that e-recruitment is a popular strategy for various positions, from blue-collar roles to white-collar and professional positions. The benefits of e-recruitment have been identified in the literature. Girard & Fallery (2009) argues that e-recruitment helps to save time for organisations and employees.

Employers can use several methods to post jobs in as little as 20 minutes. There are no limits to ad size, and they can receive resumes immediately. In contrast, the traditional methods require some time to appear, for example, in a newspaper, and might be there for a limited period.

Section 3 – Conclusion

When writing the dissertation literature review conclusion, you should always include a summary of the key findings which emerged from the literature and their relevance and significance to your research objectives.

Literature Review for Dissertation

If you are writing a dissertation literature review, you will be required to demonstrate how your research helped to fill an evident gap in research and contributed to the current knowledge in the field. Similarly, you can explain how you used the existing patterns, themes, and theories to develop your research framework.

Literature Review as an Individual Assignment

You can summarize your review of your literature’s significance and implications and provide recommendations for future work based on the gaps in existing knowledge you acknowledged.

6. Proofread

Finally, thoroughly proofread your literature review for grammatical, structural, spelling, and factual errors before submitting it to your university.

If you are unable to proofread and edit your paper, then you could take advantage of our  editing and proofreading service , which is designed to ensure that your completed literature review satisfies each of your module or project’s requirements. We have Masters and PhD qualified writers in all academic subjects, so you can be confident that they will edit and improve the quality of your to 2:1 or First Class standard, as required.

Valuable Tips for Writing Dissertation Literature Review

Your literature review must systematically comply with your research area. Underneath, we are stating some essential guidelines for a compact literature review.

Contribute to the Literature

After carefully reviewing the literature, search for the gaps in knowledge and state how you have analysed the literature with a different perspective and contributed to your research area.

Keep your Argument Systematic & Consistent

Your arguments must be consistent and systematic while discussing theories and controversial and debatable content. Be logical in your review and avoid vague statements, not to make it complex for the readers.

Provide Adequate References

Don’t forget to provide references, as they are the soul of the dissertation. While discussing different aspects of the research, provide a reasonable number of references, as your discussion and interpretations must be backed up by relevant evidence. You can see an example provided in the sample paragraph above.

Be Precise While Writing a Review

You aren’t required to write every inch of information you have studied while reviewing the literature. You will be able to find tons of information that will correlate with your research area.

Be precise while writing the review, as writing unnecessary, irrelevant information won’t give a good impression. State the most reliable sources in your review without jumping into every possible source.

Don’t go Excessively for Direct Quotes

Direct quoting is required to make a point more impactful, but you should opt for it to a specific limit. Making excessive use of it won’t be a good idea.

The direct quote is mainly used when you think that the words being used by the actual author are so authentic in their meaning that you can’t replace or rephrase them. Try to avoid relying too much on a single author/s work.

Discussing their contributions and keeping the review going briefly would be better. While mentioning the points discussed by the prior researchers – link your arguments with their discussion. Don’t write the crux of their discussion, yet tell if your argument goes along with them.

Express your Analysis

The literature review is written to summarize your perspective, which should be backed up in light of the literature. Critically analyze literature with a rational approach and express your opinion on it.

Use the Correct Referencing Style

While referencing, one must use proper referencing styles, i.e., Harvard reference style, etc. Different referencing styles are used for in-text citations, while different for end-text citations.

The Methodology Chapter

The methodology chapter flows organically from the literature review. This means that at this stage you should have reviewed the literature in your field of study, analysed research that has been conducted and highlighted how it was conducted. In turn, this should reflect the foundation of your own project as you will have to link it to your chosen research method.  

The methodology chapter also involves describing your method in detail and justifying the approach you are going to adopt, taking into consideration the limitations and ethical implications of your model. Your description should be detailed enough that someone reading your methodology can recreate your approach. 

Therefore, the methodology requires you to:

• describe your methods
• demonstrate a clear connection between your research question (or hypothesis) and the means by which you will reach your conclusions 
• present justification (strengths) and limitations (weaknesses) of your methods  

What are Methods & Methodology?

Methods 

In order to appreciate what methods are, let us remember what research is about. Research can be summarised into three points (Cottrell, 2014, p9): 

A question 

Methods of arriving at an answer 

The answer 

Thus, methods are the means to research and answer the research question, or test the hypothesis. Methods include techniques and procedures used to obtain and analyse data (Saunders, Lewis and Thornhill, 2015, p4). Your methods can consist of primary and secondary sources, qualitative, quantitative and mixed methods, as illustrated in this guide.  

Methodology 

Methodology is sometimes used interchangeably with methods, or as the set of methods used in a research. More specifically, as the name would suggest, methodo-logy is the logos, the reasoning, on the methods. It is also referred to as the theory of how research should be undertaken (Saunders, Lewis and Thornhill, 2015, p4). This is why you normally would have a methodology, rather than methods, chapter in a dissertation.  

First Key Tip

We hope this guide will be helpful, but it is of fundamental importance that you also use a  research methods book  (or other authoritative source) for your discipline . The book will guide you on best methods for your research, give you practical guidance, and present critical insights and limitations of the methods.

Dissertation Methodology

In any research, the methodology chapter is one of the key components of your dissertation. It provides a detailed description of the methods you used to conduct your research and helps readers understand how you obtained your data and how you plan to analyze it. This section is crucial for replicating the study and validating its results.

Here are the basic elements that are typically included in a dissertation methodology:

• Introduction : This section should explain the importance and goals of your research .
• Research Design : Outline your research approach and why it’s appropriate for your study. You might be conducting an experimental research, a qualitative research, a quantitative research, or a mixed-methods research.
• Data Collection : This section should detail the methods you used to collect your data. Did you use surveys, interviews, observations, etc.? Why did you choose these methods? You should also include who your participants were, how you recruited them, and any ethical considerations.
• Data Analysis : Explain how you intend to analyze the data you collected. This could include statistical analysis, thematic analysis, content analysis, etc., depending on the nature of your study.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your study. For instance, you could discuss measures taken to reduce bias, how you ensured that your measures accurately capture what they were intended to, or how you will handle any limitations in your study.
• Ethical Considerations : This is where you state how you have considered ethical issues related to your research, how you have protected the participants’ rights, and how you have complied with the relevant ethical guidelines.
• Limitations : Acknowledge any limitations of your methodology, including any biases and constraints that might have affected your study.
• Summary : Recap the key points of your methodology chapter, highlighting the overall approach and rationalization of your research.

Types of Dissertation Methodology

The type of methodology you choose for your dissertation will depend on the nature of your research question and the field you’re working in. Here are some of the most common types of methodologies used in dissertations:

Experimental Research

This involves creating an experiment that will test your hypothesis. You’ll need to design an experiment, manipulate variables, collect data, and analyze that data to draw conclusions. This is commonly used in fields like psychology, biology, and physics.

Survey Research

This type of research involves gathering data from a large number of participants using tools like questionnaires or surveys. It can be used to collect a large amount of data and is often used in fields like sociology, marketing, and public health.

Qualitative Research

This type of research is used to explore complex phenomena that can’t be easily quantified. Methods include interviews, focus groups, and observations. This methodology is common in fields like anthropology, sociology, and education.

Quantitative Research

Quantitative research uses numerical data to answer research questions. This can include statistical, mathematical, or computational techniques. It’s common in fields like economics, psychology, and health sciences.

Case Study Research

This type of research involves in-depth investigation of a particular case, such as an individual, group, or event. This methodology is often used in psychology, social sciences, and business.

Mixed Methods Research

This combines qualitative and quantitative research methods in a single study. It’s used to answer more complex research questions and is becoming more popular in fields like social sciences, health sciences, and education.

Action Research

This type of research involves taking action and then reflecting upon the results. This cycle of action-reflection-action continues throughout the study. It’s often used in fields like education and organizational development.

Longitudinal Research

This type of research involves studying the same group of individuals over an extended period of time. This could involve surveys, observations, or experiments. It’s common in fields like psychology, sociology, and medicine.

Ethnographic Research

This type of research involves the in-depth study of people and cultures. Researchers immerse themselves in the culture they’re studying to collect data. This is often used in fields like anthropology and social sciences.

Structure of Dissertation Methodology

The structure of a dissertation methodology can vary depending on your field of study, the nature of your research, and the guidelines of your institution. However, a standard structure typically includes the following elements:

• Introduction : Briefly introduce your overall approach to the research. Explain what you plan to explore and why it’s important.
• Research Design/Approach : Describe your overall research design. This can be qualitative, quantitative, or mixed methods. Explain the rationale behind your chosen design and why it is suitable for your research questions or hypotheses.
• Data Collection Methods : Detail the methods you used to collect your data. You should include what type of data you collected, how you collected it, and why you chose this method. If relevant, you can also include information about your sample population, such as how many people participated, how they were chosen, and any relevant demographic information.
• Data Analysis Methods : Explain how you plan to analyze your collected data. This will depend on the nature of your data. For example, if you collected quantitative data, you might discuss statistical analysis techniques. If you collected qualitative data, you might discuss coding strategies, thematic analysis, or narrative analysis.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your research. This might include steps you took to reduce bias or increase the accuracy of your measurements.
• Ethical Considerations : If relevant, discuss any ethical issues associated with your research. This might include how you obtained informed consent from participants, how you ensured participants’ privacy and confidentiality, or any potential conflicts of interest.
• Limitations : Acknowledge any limitations in your research methodology. This could include potential sources of bias, difficulties with data collection, or limitations in your analysis methods.
• Summary/Conclusion : Briefly summarize the key points of your methodology, emphasizing how it helps answer your research questions or hypotheses.

Example of Dissertation Methodology

An Example of Dissertation Methodology is as follows:

Chapter 3: Methodology

• Introduction

This chapter details the methodology adopted in this research. The study aimed to explore the relationship between stress and productivity in the workplace. A mixed-methods research design was used to collect and analyze data.

Research Design

This study adopted a mixed-methods approach, combining quantitative surveys with qualitative interviews to provide a comprehensive understanding of the research problem. The rationale for this approach is that while quantitative data can provide a broad overview of the relationships between variables, qualitative data can provide deeper insights into the nuances of these relationships.

Data Collection Methods

Quantitative Data Collection : An online self-report questionnaire was used to collect data from participants. The questionnaire consisted of two standardized scales: the Perceived Stress Scale (PSS) to measure stress levels and the Individual Work Productivity Questionnaire (IWPQ) to measure productivity. The sample consisted of 200 office workers randomly selected from various companies in the city.

Qualitative Data Collection : Semi-structured interviews were conducted with 20 participants chosen from the initial sample. The interview guide included questions about participants’ experiences with stress and how they perceived its impact on their productivity.

Data Analysis Methods

Quantitative Data Analysis : Descriptive and inferential statistics were used to analyze the survey data. Pearson’s correlation was used to examine the relationship between stress and productivity.

Qualitative Data Analysis : Interviews were transcribed and subjected to thematic analysis using NVivo software. This process allowed for identifying and analyzing patterns and themes regarding the impact of stress on productivity.

Reliability and Validity

To ensure reliability and validity, standardized measures with good psychometric properties were used. In qualitative data analysis, triangulation was employed by having two researchers independently analyze the data and then compare findings.

Ethical Considerations

All participants provided informed consent prior to their involvement in the study. They were informed about the purpose of the study, their rights as participants, and the confidentiality of their responses.

Limitations

The main limitation of this study is its reliance on self-report measures, which can be subject to biases such as social desirability bias. Moreover, the sample was drawn from a single city, which may limit the generalizability of the findings.

Where to Write Dissertation Methodology

In a dissertation or thesis, the Methodology section usually follows the Literature Review. This placement allows the Methodology to build upon the theoretical framework and existing research outlined in the Literature Review, and precedes the Results or Findings section. Here’s a basic outline of how most dissertations are structured:

• Acknowledgements
• Literature Review (or it may be interspersed throughout the dissertation)
• Methodology
• Results/Findings
• References/Bibliography

In the Methodology chapter, you will discuss the research design, data collection methods, data analysis methods, and any ethical considerations pertaining to your study. This allows your readers to understand how your research was conducted and how you arrived at your results.

Advantages of Dissertation Methodology

The dissertation methodology section plays an important role in a dissertation for several reasons. Here are some of the advantages of having a well-crafted methodology section in your dissertation:

• Clarifies Your Research Approach : The methodology section explains how you plan to tackle your research question, providing a clear plan for data collection and analysis.
• Enables Replication : A detailed methodology allows other researchers to replicate your study. Replication is an important aspect of scientific research because it provides validation of the study’s results.
• Demonstrates Rigor : A well-written methodology shows that you’ve thought critically about your research methods and have chosen the most appropriate ones for your research question. This adds credibility to your study.
• Enhances Transparency : Detailing your methods allows readers to understand the steps you took in your research. This increases the transparency of your study and allows readers to evaluate potential biases or limitations.
• Helps in Addressing Research Limitations : In your methodology section, you can acknowledge and explain the limitations of your research. This is important as it shows you understand that no research method is perfect and there are always potential weaknesses.
• Facilitates Peer Review : A detailed methodology helps peer reviewers assess the soundness of your research design. This is an important part of the publication process if you aim to publish your dissertation in a peer-reviewed journal.
• Establishes the Validity and Reliability : Your methodology section should also include a discussion of the steps you took to ensure the validity and reliability of your measurements, which is crucial for establishing the overall quality of your research.

Dissertation proposals

What are dissertation proposals.

A dissertation proposal is an outline of your proposed research project. It is what you imagine your dissertation might look like before you start. Consider it a temporary document which might change during the negotiation process between you and your dissertation supervisor.  The proposal can help you clarify exactly what you want to cover in your dissertation. It can also outline how you are going to approach it. Your dissertation plan and structure might change throughout this process as you develop your ideas. Your proposal is the first step towards your goal: a completed dissertation.

Structuring your dissertation proposal

The structure, content, and length of your dissertation proposal will depend on your course requirements. Some courses may require that your aims and objectives are separate from the main body of the proposal. You might be expected to write a literature review, and/or provide a detailed methodology. You might also be asked to include an extensive context for your proposed study. Consult your module handbook or assignment brief for the specific requirements of your course. 

Give each section of your proposal a heading You can also experiment with giving your proposed dissertation a title. Both of these approaches may help you focus and stay on topic. Most dissertation proposals will have a fairly standard structure, under the following headings:

Sections of a dissertation proposal

• Aims and objectives
• Rationale for your study
• Methodology
• Brief literature review
• Benefits of your research

Describe what you plan to investigate. You could write a statement of your topic, a research question(s), or a hypothesis.

• Explain why you want to do this research.
• Write a justification as to why the project is worth undertaking.
• Reasons might include: a gap in existing research; questioning or extending the findings of earlier research; replicating a piece of research to test its reliability.
• Describe and justify how you plan to do the research.
• You might be reviewing the work of others, which mainly involves secondary, or desk-based, research. Or you might plan to collect data yourself, which is primary research. It is common for undergraduate dissertations to involve a mixture of these.
• If you are doing secondary research, describe how you will select your sources. For primary research, describe how you will collect your data. This might include using questionnaires, interviews, archival research, or other methods. 
• Others will have researched this topic before, or something similar.
• The literature review allows you to outline what they have found and where your project fits in. For example, you could highlight disagreements or discrepancies in the existing research.

Outline who might potentially gain from your research and what you might find out or expand upon. For example, there could be implications for practice in a particular profession.

Dissertation style and language

A dissertation is a logical, structured, argument-based exploration of a topic. The style of your writing may vary slightly in each chapter. For example, your results chapter should display factual information, whereas your analysis chapter might be more argument-based. Make sure your language, tone and abbreviations are consistent within each section. Your language should be formal and contain terminology relevant to your subject area. Dissertations have a large word count. It is important to structure your work with headings and a contents page. Use signposting language to help your reader understand the flow of your writing. Charts, tables or images may help you communicate specific information. 

Top tip!  To signpost in your dissertation, use the ‘Signalling Transition’ section of the  Manchester Academic Phrasebank .

Introduction: A rapid literature review (RLR) is an alternative to systematic literature review (SLR) that can speed up the analysis of newly published data. The objective was to identify and summarize available information regarding different approaches to defining RLR and the methodology applied to the conduct of such reviews.

Methods: The Medline and EMBASE databases, as well as the grey literature, were searched using the set of keywords and their combination related to the targeted and rapid review, as well as design, approach, and methodology. Of the 3,898 records retrieved, 12 articles were included.

Results: Specific definition of RLRs has only been developed in 2021. In terms of methodology, the RLR should be completed within shorter timeframes using simplified procedures in comparison to SLRs, while maintaining a similar level of transparency and minimizing bias. Inherent components of the RLR process should be a clear research question, search protocol, simplified process of study selection, data extraction, and quality assurance.

Conclusions: There is a lack of consensus on the formal definition of the RLR and the best approaches to perform it. The evidence-based supporting methods are evolving, and more work is needed to define the most robust approaches.

Introduction

A systematic literature review (SLR) summarizes the results of all available studies on a specific topic and provides a high level of evidence. Authors of the SLR have to follow an advanced plan that covers defining a priori information regarding the research question, sources they are going to search, inclusion criteria applied to choose studies answering the research question, and information regarding how they are going to summarize findings [ 1 ].

The rigor and transparency of SLRs make them the most reliable form of literature review [ 2 ], providing a comprehensive, objective summary of the evidence for a given topic [ 3 , 4 ]. On the other hand, the SLR process is usually very time-consuming and requires a lot of human resources. Taking into account a high increase of newly published data and a growing need to analyze information in the fastest possible way, rapid literature reviews (RLRs) often replace standard SLRs.

There are several guidelines on the methodology of RLRs [ 5–11 ]; however, only recently, one publication from 2021 attempted to construct a unified definition [ 11 ]. Generally, by RLRs, researchers understand evidence synthesis during which some of the components of the systematic approach are being used to facilitate answering a focused research question; however, scope restrictions and a narrower search strategy help to make the project manageable in a shorter time and to get the key conclusions faster [ 4 ].

The objective of this research was to collect and summarize available information on different approaches to the definition and methodology of RLRs. An RLR has been run to capture publications providing data that fit the project objective.

To find publications reporting information on the methodology of RLRs, searches were run in the Medline and EMBASE databases in November 2022. The following keywords were searched for in titles and abstracts: ‘targeted adj2 review’ OR ‘focused adj2 review’ OR ‘rapid adj2 review’, and ‘methodology’ OR ‘design’ OR ‘scheme’ OR ‘approach’. The grey literature was identified using Google Scholar with keywords including ‘targeted review methodology’ OR ‘focused review methodology’ OR ‘rapid review methodology’. Only publications in English were included, and the date of publication was restricted to year 2016 onward in order to identify the most up-to-date literature. The reference lists of each included article were searched manually to obtain the potentially eligible articles. Titles and abstracts of the retrieved records were first screened to exclude articles that were evidently irrelevant. The full texts of potentially relevant papers were further reviewed to examine their eligibility.

A pre-defined Excel grid was developed to extract the following information related to the methodology of RLR from guidelines:

• Definition,
• Research question and searches,
• Studies selection,
• Data extraction and quality assessment,
• Additional information.

There was no restriction on the study types to be analyzed; any study reporting on the methodology of RLRs could be included: reviews, practice guidelines, commentaries, and expert opinions on RLR relevant to healthcare policymakers or practitioners. The data extraction and evidence summary were conducted by one analyst and further examined by a senior analyst to ensure that relevant information was not omitted. Disagreements were resolved by discussion and consensus.

Studies selection

A total of 3,898 records (3,864 articles from a database search and 34 grey literature from Google Scholar) were retrieved. After removing duplicates, titles and abstracts of 3,813 articles were uploaded and screened. The full texts of 43 articles were analyzed resulting in 12 articles selected for this review, including 7 guidelines [ 5–11 ] on the methodology of RLRs, together with 2 papers summarizing the results of the Delphi consensus on the topic [ 12 , 13 ], and 3 publications analyzing and assessing different approaches to RLRs [ 4 , 14 , 15 ].

Overall, seven guidelines were identified: from the World Health Organization (WHO) [ 5 ], National Collaborating Centre for Methods and Tools (NCCMT) [ 7 ], the UK government [ 8 ], the Oxford Centre for Evidence Based Medicine [ 9 ], the Cochrane group [ 6 , 11 ], and one multi-national review [ 10 ]. Among the papers that did not describe the guidelines, Gordon et al. [ 4 ] proposed 12 tips for conducting a rapid review in the right settings and discussed why these reviews may be more beneficial in some circumstances. The objective of work conducted by Tricco et al. [ 13 ] and Pandor et al. [ 12 ] was to collect and compare perceptions of rapid reviews from stakeholders, including researchers, policymakers, industry, journal editors, and healthcare providers, and to reach a consensus outlining the domains to consider when deciding on approaches for RLRs. Haby et al. [ 14 ] run a rapid review of systematic reviews and primary studies to find out the best way to conduct an RLR in health policy and practice. In Tricco et al. (2022) [ 15 ], JBI position statement for RLRs is presented.

From all the seven identified guidelines information regarding definitions the authors used for RLRs, approach to the PICOS criteria and search strategy development, studies selection, data extractions, quality assessment, and reporting were extracted.

Cochrane Rapid Reviews Methods Group developed methods guidance based on scoping review of the underlying evidence, primary methods studies conducted, as well as surveys sent to Cochrane representative and discussion among those with expertise [ 11 ]. They analyzed over 300 RLRs or RLR method papers and based on the methodology of those studies, constructed a broad definition RLR, one that meets a minimum set of requirements identified in the thematic analysis: ‘ A rapid review is a form of knowledge synthesis that accelerates the process of conducting a traditional systematic review through streamlining or omitting a variety of methods to produce evidence in a resource-efficient manner .’ This interpretation aligns with more than 50% of RLRs identified in this study. The authors additionally provided several other definitions, depending on specific situations or requirements (e.g., when RLR is produced on stakeholder’s request). It was additionally underlined that RLRs should be driven by the need of timely evidence for decision-making purposes [ 11 ].

Rapid reviews vary in their objective, format, and methods used for evidence synthesis. This is a quite new area, and still no agreement on optimal methods can be found [ 5 ]. All of the definitions are highlighting that RLRs are completed within shorter timeframes than SLRs, and also lack of time is one of the main reasons they are conducted. It has been suggested that most rapid reviews are conducted within 12 weeks; however, some of the resources suggest time between a few weeks to no more than 6 months [ 5 , 6 ]. Some of the definitions are highlighting that RLRs follow the SLR process, but certain phases of the process are simplified or omitted to retrieve information in a time-saving way [ 6 , 7 ]. Different mechanisms are used to enhance the timeliness of reviews. They can be used independently or concurrently: increasing the intensity of work by intensifying the efforts of multiple analysts by parallelization of tasks, using review shortcuts whereby one or more systematic review steps may be reduced, automatizing review steps by using new technologies [ 5 ]. The UK government report [ 8 ] referred to two different RLRs: in the form of quick scoping reviews (QSR) or rapid evidence assessments (REA). While being less resource and time-consuming compared to standard SLRs, QSRs and REAs are designed to be similarly transparent and to minimize bias. QSRs can be applied to rather open-ended questions, e.g., ‘what do we know about something’ but both, QSRs and REAs, provide an understanding of the volume and characteristics of evidence on a specific topic, allowing answering questions by maximizing the use of existing data, and providing a clear picture of the adequacy of existing evidence [ 8 ].

Research questions and searches

The guidelines suggest creating a clear research question and search protocol at the beginning of the project. Additionally, to not duplicate RLRs, the Cochrane Rapid Reviews Methods Group encourages all people working on RLRs to consider registering their search protocol with PROSPERO, the international prospective register of reviews; however, so far they are not formally registered in most cases [ 5 , 6 ]. They also recommend involving key stakeholders (review users) to set and refine the review question, criteria, and outcomes, as well as consulting them through the entire process [ 11 ].

Regarding research questions, it is better to structure them in a neutral way rather than focus on a specific direction for the outcome. By doing so, the researcher is in a better position to identify all the relevant evidence [ 7 ]. Authors can add a second, supportive research question when needed [ 8 ]. It is encouraged to limit the number of interventions, comparators and outcomes, to focus on the ones that are most important for decision-making [ 11 ]. Useful could be also reviewing additional materials, e.g., SLRs on the topic, as well as conducting a quick literature search to better understand the topic before starting with RLRs [ 7 ]. In SLRs researchers usually do not need to care a lot about time spent on creating PICOS, they need to make sure that the scope is broad enough, and they cannot use many restrictions. When working on RLRs, a reviewer may spend more or less time defining each of the components of the study question, and the main step is making sure that PICOS addresses the needs of those who requested the rapid review, and at the same time, it is feasible within the required time frame [ 7 ]. Search protocol should contain an outline of how the following review steps are to be carried out, including selected search keywords and a full strategy, a list of data sources, precise inclusion and exclusion criteria, a strategy for data extraction and critical appraisal, and a plan of how the information will be synthesized [ 8 ].

In terms of searches running, in most cases, an exhaustive process will not be feasible. Researchers should make sure that the search is effective and efficient to produce results in a timely manner. Cochrane Rapid Reviews Methods Group recommends involving an information specialist and conducting peer review of at least one search strategy [ 11 ]. According to the rapid review guidebook by McMaster University [ 7 ], it is important that RLRs, especially those that support policy and program decisions, are being fed by the results of a body of literature, rather than single studies, when possible. It would result in more generalizable findings applied at the level of a population and serve more realistic findings for program decisions [ 7 ]. It is important to document the search strategy, together with a record of the date and any date limits of the search, so that it can easily be run again, modified, or updated. Furthermore, the information on the individual databases included in platform services should always be reported, as this depends on organizations’ subscriptions and must be included for transparency and repeatability [ 7 , 8 ]. Good solution for RLRs is narrowing the scope or searching a limited number of databases and other sources [ 7 ]. Often, the authors use the PubMed/MEDLINE, Cochrane Library, and Embase databases. In most reviews, two or more databases are searched, and common limits are language (usually restricted to English), date, study design, and geographical area. Some RLRs include searching of grey literature; however, contact with authors is rather uncommon [ 5 , 8 ]. According to the flexible framework for restricted systematic review published by the University of Oxford, the search should be run in at least one major scientific database such as PubMed, and one other source, e.g., Google Scholar [ 9 ]. Grey literature and unpublished evidence may be particularly needed and important for intervention questions. It is related to the fact that studies that do not report the effects of interventions are less likely to be published [ 8 ]. If there is any type of evidence that will not be considered by the RLRs, e.g., reviews or theoretical and conceptual studies, it should also be stated in the protocol together with justification [ 8 ]. Additionally, authors of a practical guide published by WHO suggest using a staged search to identify existing SLRs at the beginning, and then focusing on studies with other designs [ 5 ]. If a low number of citations have been retrieved, it is acceptable to expand searches, remove some of the limits, and add additional databases and sources [ 7 ].

Searching for RLRs is an iterative process, and revising the approach is usually needed [ 7 ]. Changes should be confirmed with stakeholders and should be tracked and reflected in the final report [ 5 ].

The next step in the rapid review is the selection of studies consisting of two phases: screening of titles and abstracts, and analysis of full texts. Prior to screening initiation, it is recommended to conduct a pilot exercise using the same 30–50 abstracts and 5–10 full-texts for the entire screening team in order to calibrate and test the review form [ 11 ]. In contrast to SLRs, it can be done by one reviewer with or without verification by a second one. If verification is performed, usually the second reviewer checks only a subset of records and compares them. Cochrane Group, in contrast, recommends a stricter approach: at least 20% of references should be double-screened at titles and abstracts stage, and while the rest of the references may be screened by one reviewer, the excluded items need to be re-examined by second reviewer; similar approach is used in full-text screening [ 11 ]. This helps to ensure that bias was reduced and that the PICOS criteria are applied in a relevant way [ 5 , 8 , 9 , 11 ]. During the analysis of titles and abstracts, there is no need to report reasons for exclusion; however, they should be tracked for all excluded full texts [ 7 ].

Data extraction and quality assessment

According to the WHO guide, the most common method for data extraction in RLRs is extraction done by a single reviewer with or without partial verification. The authors point out that a reasonable approach is to use a second reviewer to check a random sample of at least 10% of the extractions for accuracy. Dual performance is more necessary for the extraction of quantitative results than for descriptive study information. In contrast, Cochrane group recommends that second reviewer should check the correctness and completeness of all data [ 11 ]. When possible, extractions should be limited to key characteristics and outcomes of the study. The same approach to data extraction is also suggested for a quality assessment process within rapid reviews [ 5 , 9 , 11 ]. Authors of the guidebook from McMaster University highlight that data extraction should be done ideally by two reviewers independently and consensus on the discrepancies should always be reached [ 7 ]. The final decision on the approach to this important step of review should depend on the available time and should also reflect the complexity of the research question [ 9 ].

For screening, analysis of full texts, extractions, and quality assessments, researchers can use information technologies to support them by making these review steps more efficient [ 5 ].

Before data reporting, a reviewer should prepare a document with key message headings, executive summary, background related to the topic and status of the current knowledge, project question, synthesis of findings, conclusions, and recommendations. According to the McMaster University guidebook, a report should be structured in a 1:2:20 format, that is, one page for key messages, two pages for an executive summary, and a full report of up to 20 pages [ 7 ]. All the limitations of the RLRs should be analyzed, and conclusions should be drawn with caution [ 5 ]. The quality of the accumulated evidence and the strength of recommendations can be assessed using, e.g., the GRADE system [ 5 ]. When working on references quoting, researchers should remember to use a primary source, not secondary references [ 7 ]. It would be worth considering the support of some software tools to automate reporting steps. Additionally, any standardization of the process and the usage of templates can support report development and enhance the transparency of the review [ 5 ].

Ideally, all the review steps should be completed during RLRs; however, often some steps may need skipping or will not be completed as thoroughly as should because of time constraints. It is always crucial to decide which steps may be skipped, and which are the key ones, depending on the project [ 7 ]. Guidelines suggest that it may be helpful to invite researchers with experience in the operations of SLRs to participate in the rapid review development [ 5 , 9 ]. As some of the steps will be completed by one reviewer only, it is important to provide them with relevant training at the beginning of the process, as well as during the review, to minimize the risk of mistakes [ 5 ].

Additional information

Depending on the policy goal and available resources and deadlines, methodology of the RLRs may be modified. Wilson et al. [ 10 ] provided extensive guidelines for performing RLR within days (e.g., to inform urgent internal policy discussions and/or management decisions), weeks (e.g., to inform public debates), or months (e.g., to inform policy development cycles that have a longer timeline, but that cannot wait for a traditional full systematic review). These approaches vary in terms of data synthesis, types of considered evidence and project management considerations.

In shortest timeframes, focused questions and subquestions should be formulated, typically to conduct a policy analysis; the report should consist of tables along with a brief narrative summary. Evidence from SLRs is often considered, as well as key informant interviews may be conducted to identify additional literature and insights about the topic, while primary studies and other types of evidence are not typically feasible due to time restrictions. The review would be best conducted with 1–2 reviewers sharing the work, enabling rapid iterations of the review. As for RLRs with longer timeline (weeks), these may use a mix of policy, systems and political analysis. Structure of the review would be similar to shorter RLRs – tabular with short narrative summary, as the timeline does not allow for comprehensive synthesis of data. Besides SLRs, primary studies and other evidence may be feasible in this timeframe, if obtained using the targeted searches in the most relevant databases. The review team should be larger, and standardized procedures for reviewing of the results and data extraction should be applied. In contrast to previous timeframe, merit review process may be feasible. For both timeframes, brief consultations with small transdisciplinary team should be conducted at the beginning and in the final stage of the review to discuss important matters.

For RLRs spanning several months, more comprehensive methodology may be adapted in terms of data synthesis and types of evidence. However, authors advise that review may be best conducted with a small review team in order to allow for more in-depth interpretation and iteration.

Studies analyzing methodology

There have been two interesting publications summarizing the results of Delphi consensus on the RLR methodology identified and included in this review [ 12 , 13 ].

Tricco et al. [ 13 ] first conducted an international survey and scoping review to collect information on the possible approaches to the running of rapid reviews, based on which, they employed a modified Delphi method that included inputs from 113 stakeholders to explore the most optimized approach. Among the six most frequent rapid review approaches (not all detailed here) being evaluated, the approach that combines inclusion of published literature only, a search of more than one database and limitations by date and language, study selection by one analyst, data extraction, and quality assessment by one analyst and one verifier, was perceived as the most feasible approach (72%, 81/113 responses) with the potentially lowest risk of bias (12%, 12/103). The approach ranked as the first one when considering timelines assumes updating of the search from a previously published review, no additional limits on search, studies selection and data extraction done by one reviewer, and no quality assessment. Finally, based on the publication, the most comprehensive RLRs can be made by moving on with the following rules: searching more than one database and grey literature and using date restriction, and assigning one reviewer working on screening, data extraction, and risk of bias assessment ( Table 1 ). Pandor et al. [ 12 ] introduced a decision tool for SelecTing Approaches for Rapid Reviews (STARR) that were produced through the Delphi consensus of international experts through an iterative and rigorous process. Participants were asked to assess the importance of predefined items in four domains related to the rapid review process: interaction with commissioners, understanding the evidence base, data extraction and synthesis methods, and reporting of rapid review methods. All items assigned to four domains achieved > 70% of consensus, and in that way, the first consensus-driven tool has been created that supports authors of RLRs in planning and deciding on approaches.

Six most frequent approaches to RLRs (adapted from Tricco et al. [ 13 ]).

Haby et al. [ 14 ] run searches of 11 databases and two websites and developed a comprehensive overview of the methodology of RLRs. With five SLRs and one RCT being finally included, they identified the following approaches used in RLRs to make them faster than full SLRs: limiting the number and scope of questions, searching fewer databases, limited searching of grey literature, restrictions on language and date (e.g., English only, most recent publications), updating the existing SLRs, eliminating or limiting hand searches of reference lists, noniterative search strategies, eliminating consultation with experts, limiting dual study selection, data extraction and quality assessment, minimal data synthesis with short concise conclusions or recommendations. All the SLRs included in this review were consistent in stating that no agreed definition of rapid reviews is available, and there is still no final agreement on the best methodological rules to be followed.

Gordon et al. [ 4 ] explained the advantages of performing a focused review and provided 12 tips for its conduction. They define focused reviews as ‘a form of knowledge synthesis in which the components of the systematic process are applied to facilitate the analysis of a focused research question’. The first tip presented by the authors is related to deciding if a focused review is a right solution for the considered project. RLRs will suit emerging topics, approaches, or assessments where early synthesis can support doctors, policymakers, etc., but also can direct future research. The second, third, and fourth tips highlight the importance of running preliminary searches and considering narrowing the results by using reasonable constraints taking into account the local context, problems, efficiency perspectives, and available time. Further tips include creating a team of experienced reviewers working on the RLRs, thinking about the target journal from the beginning of work on the rapid review, registering the search protocol on the PROSPERO registry, and the need for contacting authors of papers when data available in publications are missing or incongruent. The last three tips are related to the choice of evidence synthesis method, using the visual presentation of data, and considering and describing all the limitations of the focused review.

Finally, a new publication by Tricco et al. from 2022, describing JBI position statement [ 15 ] underlined that for the time being, there is no specific tool for critical appraisal of the RLR’s methodological quality. Instead, reviewers may use available tools to assess the risk of bias or quality of SLRs, like ROBIS, the JBI critical appraisal tools, or the assessment of multiple systematic reviews (AMSTAR).

Inconsistency in the definitions and methodologies of RLR

Although RLR was broadly perceived as an approach to quicken the conduct of conventional SLR, there is a lack of consensus on the formal definition of the RLR, so as to the best approaches to perform it. Only in 2021, a study proposing unified definition was published; however, it is important to note that the most accurate definition was only matching slightly over 50% of papers analysed by the authors, which underlines the lack of homogeneity in the field [ 11 ]. The evidence-based supporting methods are evolving, and more evidence is needed to define the most robust approaches [ 5 ].

Diverse terms are used to describe the RLR, including ‘rapid review’, focused systematic review’, ‘quick scoping reviews’, and ‘rapid evidence assessments’. Although the general principles of conducting RLR are to accelerate the whole process, complexity was seen in the methodologies used for RLRs, as reflected in this study. Also, inconsistencies related to the scope of the questions, search strategies, inclusion criteria, study screening, full-text review, quality assessment, and evidence presentation were implied. All these factors may hamper decision-making about optimal methodologies for conducting rapid reviews, and as a result, the efficiency of RLR might be decreased. Additionally, researchers may tend to report the methodology of their reviews without a sufficient level of detail, making it difficult to appraise the quality and robustness of their work.

Although RLR used simplified approaches for evidence synthesis compared with SLR, the methodologies for RLR should be replicable, rigorous, and transparent to the greatest extent [ 16 ]. When time and resources are limited, RLR could be a practical and efficient tool to provide the summary of evidence that is critical for making rapid clinical or policy-related decisions [ 5 ]. Focusing on specific questions that are of controversy or special interest could be powerful in reaffirming whether the existing recommendation statements are still appropriate [ 17 ].

The weakness of RLR should also be borne in mind, and the trade-off of using RLR should be carefully considered regarding the thoroughness of the search, breadth of a research question, and depth of analysis [ 18 ]. If allowed, SLR is preferred over RLR considering that some relevant studies might be omitted with narrowed search strategies and simplified screening process [ 14 ]. Additionally, omitting the quality assessment of included studies could result in an increased risk of bias, making the comprehensiveness of RLR compromised [ 13 ]. Furthermore, in situations that require high accuracy, for example, where a small relative difference in an intervention has great impacts, for the purpose of drafting clinical guidelines, or making licensing decisions, a comprehensive SLR may remain the priority [ 19 ]. Therefore, clear communications with policymakers are recommended to reach an agreement on whether an RLR is justified and whether the methodologies of RLR are acceptable to address the unanswered questions [ 18 ].

Dissertation Structure & Layout 101: How to structure your dissertation, thesis or research project.

By: Derek Jansen (MBA) Reviewed By: David Phair (PhD) | July 2019

So, you’ve got a decent understanding of what a dissertation is , you’ve chosen your topic and hopefully you’ve received approval for your research proposal . Awesome! Now its time to start the actual dissertation or thesis writing journey.

To craft a high-quality document, the very first thing you need to understand is dissertation structure . In this post, we’ll walk you through the generic dissertation structure and layout, step by step. We’ll start with the big picture, and then zoom into each chapter to briefly discuss the core contents. If you’re just starting out on your research journey, you should start with this post, which covers the big-picture process of how to write a dissertation or thesis .

*The Caveat *

In this post, we’ll be discussing a traditional dissertation/thesis structure and layout, which is generally used for social science research across universities, whether in the US, UK, Europe or Australia. However, some universities may have small variations on this structure (extra chapters, merged chapters, slightly different ordering, etc).

So, always check with your university if they have a prescribed structure or layout that they expect you to work with. If not, it’s safe to assume the structure we’ll discuss here is suitable. And even if they do have a prescribed structure, you’ll still get value from this post as we’ll explain the core contents of each section.  

Overview: S tructuring a dissertation or thesis

• Acknowledgements page
• Abstract (or executive summary)
• Table of contents , list of figures and tables
• Chapter 1: Introduction
• Chapter 2: Literature review
• Chapter 3: Methodology
• Chapter 4: Results
• Chapter 5: Discussion
• Chapter 6: Conclusion
• Reference list

As I mentioned, some universities will have slight variations on this structure. For example, they want an additional “personal reflection chapter”, or they might prefer the results and discussion chapter to be merged into one. Regardless, the overarching flow will always be the same, as this flow reflects the research process , which we discussed here – i.e.:

• The introduction chapter presents the core research question and aims .
• The literature review chapter assesses what the current research says about this question.
• The methodology, results and discussion chapters go about undertaking new research about this question.
• The conclusion chapter (attempts to) answer the core research question .

In other words, the dissertation structure and layout reflect the research process of asking a well-defined question(s), investigating, and then answering the question – see below.

To restate that – the structure and layout of a dissertation reflect the flow of the overall research process . This is essential to understand, as each chapter will make a lot more sense if you “get” this concept. If you’re not familiar with the research process, read this post before going further.

Right. Now that we’ve covered the big picture, let’s dive a little deeper into the details of each section and chapter. Oh and by the way, you can also grab our free dissertation/thesis template here to help speed things up.

The title page of your dissertation is the very first impression the marker will get of your work, so it pays to invest some time thinking about your title. But what makes for a good title? A strong title needs to be 3 things:

• Succinct (not overly lengthy or verbose)
• Specific (not vague or ambiguous)
• Representative of the research you’re undertaking (clearly linked to your research questions)

Typically, a good title includes mention of the following:

• The broader area of the research (i.e. the overarching topic)
• The specific focus of your research (i.e. your specific context)
• Indication of research design (e.g. quantitative , qualitative , or  mixed methods ).

For example:

A quantitative investigation [research design] into the antecedents of organisational trust [broader area] in the UK retail forex trading market [specific context/area of focus].

Again, some universities may have specific requirements regarding the format and structure of the title, so it’s worth double-checking expectations with your institution (if there’s no mention in the brief or study material).

Acknowledgements

This page provides you with an opportunity to say thank you to those who helped you along your research journey. Generally, it’s optional (and won’t count towards your marks), but it is academic best practice to include this.

So, who do you say thanks to? Well, there’s no prescribed requirements, but it’s common to mention the following people:

• Your dissertation supervisor or committee.
• Any professors, lecturers or academics that helped you understand the topic or methodologies.
• Any tutors, mentors or advisors.
• Your family and friends, especially spouse (for adult learners studying part-time).

There’s no need for lengthy rambling. Just state who you’re thankful to and for what (e.g. thank you to my supervisor, John Doe, for his endless patience and attentiveness) – be sincere. In terms of length, you should keep this to a page or less.

Abstract or executive summary

The dissertation abstract (or executive summary for some degrees) serves to provide the first-time reader (and marker or moderator) with a big-picture view of your research project. It should give them an understanding of the key insights and findings from the research, without them needing to read the rest of the report – in other words, it should be able to stand alone .

For it to stand alone, your abstract should cover the following key points (at a minimum):

• Your research questions and aims – what key question(s) did your research aim to answer?
• Your methodology – how did you go about investigating the topic and finding answers to your research question(s)?
• Your findings – following your own research, what did do you discover?
• Your conclusions – based on your findings, what conclusions did you draw? What answers did you find to your research question(s)?

So, in much the same way the dissertation structure mimics the research process, your abstract or executive summary should reflect the research process, from the initial stage of asking the original question to the final stage of answering that question.

In practical terms, it’s a good idea to write this section up last , once all your core chapters are complete. Otherwise, you’ll end up writing and rewriting this section multiple times (just wasting time). For a step by step guide on how to write a strong executive summary, check out this post .

Table of contents

This section is straightforward. You’ll typically present your table of contents (TOC) first, followed by the two lists – figures and tables. I recommend that you use Microsoft Word’s automatic table of contents generator to generate your TOC. If you’re not familiar with this functionality, the video below explains it simply:

If you find that your table of contents is overly lengthy, consider removing one level of depth. Oftentimes, this can be done without detracting from the usefulness of the TOC.

Right, now that the “admin” sections are out of the way, its time to move on to your core chapters. These chapters are the heart of your dissertation and are where you’ll earn the marks. The first chapter is the introduction chapter – as you would expect, this is the time to introduce your research…

It’s important to understand that even though you’ve provided an overview of your research in your abstract, your introduction needs to be written as if the reader has not read that (remember, the abstract is essentially a standalone document). So, your introduction chapter needs to start from the very beginning, and should address the following questions:

• What will you be investigating (in plain-language, big picture-level)?
• Why is that worth investigating? How is it important to academia or business? How is it sufficiently original?
• What are your research aims and research question(s)? Note that the research questions can sometimes be presented at the end of the literature review (next chapter).
• What is the scope of your study? In other words, what will and won’t you cover ?
• How will you approach your research? In other words, what methodology will you adopt?
• How will you structure your dissertation? What are the core chapters and what will you do in each of them?

These are just the bare basic requirements for your intro chapter. Some universities will want additional bells and whistles in the intro chapter, so be sure to carefully read your brief or consult your research supervisor.

If done right, your introduction chapter will set a clear direction for the rest of your dissertation. Specifically, it will make it clear to the reader (and marker) exactly what you’ll be investigating, why that’s important, and how you’ll be going about the investigation. Conversely, if your introduction chapter leaves a first-time reader wondering what exactly you’ll be researching, you’ve still got some work to do.

Now that you’ve set a clear direction with your introduction chapter, the next step is the literature review . In this section, you will analyse the existing research (typically academic journal articles and high-quality industry publications), with a view to understanding the following questions:

• What does the literature currently say about the topic you’re investigating?
• Is the literature lacking or well established? Is it divided or in disagreement?
• How does your research fit into the bigger picture?
• How does your research contribute something original?
• How does the methodology of previous studies help you develop your own?

Depending on the nature of your study, you may also present a conceptual framework towards the end of your literature review, which you will then test in your actual research.

Again, some universities will want you to focus on some of these areas more than others, some will have additional or fewer requirements, and so on. Therefore, as always, its important to review your brief and/or discuss with your supervisor, so that you know exactly what’s expected of your literature review chapter.

Now that you’ve investigated the current state of knowledge in your literature review chapter and are familiar with the existing key theories, models and frameworks, its time to design your own research. Enter the methodology chapter – the most “science-ey” of the chapters…

In this chapter, you need to address two critical questions:

• Exactly HOW will you carry out your research (i.e. what is your intended research design)?
• Exactly WHY have you chosen to do things this way (i.e. how do you justify your design)?

Remember, the dissertation part of your degree is first and foremost about developing and demonstrating research skills . Therefore, the markers want to see that you know which methods to use, can clearly articulate why you’ve chosen then, and know how to deploy them effectively.

Importantly, this chapter requires detail – don’t hold back on the specifics. State exactly what you’ll be doing, with who, when, for how long, etc. Moreover, for every design choice you make, make sure you justify it.

In practice, you will likely end up coming back to this chapter once you’ve undertaken all your data collection and analysis, and revise it based on changes you made during the analysis phase. This is perfectly fine. Its natural for you to add an additional analysis technique, scrap an old one, etc based on where your data lead you. Of course, I’m talking about small changes here – not a fundamental switch from qualitative to quantitative, which will likely send your supervisor in a spin!

You’ve now collected your data and undertaken your analysis, whether qualitative, quantitative or mixed methods. In this chapter, you’ll present the raw results of your analysis . For example, in the case of a quant study, you’ll present the demographic data, descriptive statistics, inferential statistics , etc.

Typically, Chapter 4 is simply a presentation and description of the data, not a discussion of the meaning of the data. In other words, it’s descriptive, rather than analytical – the meaning is discussed in Chapter 5. However, some universities will want you to combine chapters 4 and 5, so that you both present and interpret the meaning of the data at the same time. Check with your institution what their preference is.

Now that you’ve presented the data analysis results, its time to interpret and analyse them. In other words, its time to discuss what they mean, especially in relation to your research question(s).

What you discuss here will depend largely on your chosen methodology. For example, if you’ve gone the quantitative route, you might discuss the relationships between variables . If you’ve gone the qualitative route, you might discuss key themes and the meanings thereof. It all depends on what your research design choices were.

Most importantly, you need to discuss your results in relation to your research questions and aims, as well as the existing literature. What do the results tell you about your research questions? Are they aligned with the existing research or at odds? If so, why might this be? Dig deep into your findings and explain what the findings suggest, in plain English.

The final chapter – you’ve made it! Now that you’ve discussed your interpretation of the results, its time to bring it back to the beginning with the conclusion chapter . In other words, its time to (attempt to) answer your original research question s (from way back in chapter 1). Clearly state what your conclusions are in terms of your research questions. This might feel a bit repetitive, as you would have touched on this in the previous chapter, but its important to bring the discussion full circle and explicitly state your answer(s) to the research question(s).

Next, you’ll typically discuss the implications of your findings . In other words, you’ve answered your research questions – but what does this mean for the real world (or even for academia)? What should now be done differently, given the new insight you’ve generated?

Lastly, you should discuss the limitations of your research, as well as what this means for future research in the area. No study is perfect, especially not a Masters-level. Discuss the shortcomings of your research. Perhaps your methodology was limited, perhaps your sample size was small or not representative, etc, etc. Don’t be afraid to critique your work – the markers want to see that you can identify the limitations of your work. This is a strength, not a weakness. Be brutal!

This marks the end of your core chapters – woohoo! From here on out, it’s pretty smooth sailing.

The reference list is straightforward. It should contain a list of all resources cited in your dissertation, in the required format, e.g. APA , Harvard, etc.

It’s essential that you use reference management software for your dissertation. Do NOT try handle your referencing manually – its far too error prone. On a reference list of multiple pages, you’re going to make mistake. To this end, I suggest considering either Mendeley or Zotero. Both are free and provide a very straightforward interface to ensure that your referencing is 100% on point. I’ve included a simple how-to video for the Mendeley software (my personal favourite) below:

Some universities may ask you to include a bibliography, as opposed to a reference list. These two things are not the same . A bibliography is similar to a reference list, except that it also includes resources which informed your thinking but were not directly cited in your dissertation. So, double-check your brief and make sure you use the right one.

The very last piece of the puzzle is the appendix or set of appendices. This is where you’ll include any supporting data and evidence. Importantly, supporting is the keyword here.

Your appendices should provide additional “nice to know”, depth-adding information, which is not critical to the core analysis. Appendices should not be used as a way to cut down word count (see this post which covers how to reduce word count ). In other words, don’t place content that is critical to the core analysis here, just to save word count. You will not earn marks on any content in the appendices, so don’t try to play the system!

Time to recap…

And there you have it – the traditional dissertation structure and layout, from A-Z. To recap, the core structure for a dissertation or thesis is (typically) as follows:

• Acknowledgments page

Most importantly, the core chapters should reflect the research process (asking, investigating and answering your research question). Moreover, the research question(s) should form the golden thread throughout your dissertation structure. Everything should revolve around the research questions, and as you’ve seen, they should form both the start point (i.e. introduction chapter) and the endpoint (i.e. conclusion chapter).

I hope this post has provided you with clarity about the traditional dissertation/thesis structure and layout. If you have any questions or comments, please leave a comment below, or feel free to get in touch with us. Also, be sure to check out the rest of the  Grad Coach Blog .

Guide on How to Write a Literature Review for a Dissertation

If you do not know what the literature review is, we will shortly describe this term. Basically, the literature review is a section in the dissertation where you describe and evaluate the literature that is relevant to the topic of your research. This part should include your opinion regarding the literature included. 

In this article, I will tell you about how to write a literature review. However, we should also provide you with relevant reference, which would lead you to the DissertationTeam website. Here you can order help with the literature review part in case you do not want to spend a lot of time figuring out how to write it. The website has a great reputation and is known for helping hundreds of students to defend their dissertations. Therefore you can visit the literature review and find out more information about the service.

Is Dissertation Literature Review Necessary  

When students proceed to writing the dissertation they may think whether the literature review is really necessary for it. The simple answer is yes, the literature review is necessary because it is considered one of the most important elements of any dissertation and scientific paper.

The student needs to write the literature review because it shows their knowledge and background of the topic and proves that the student understands the issue they will research. The presence of the review of the literature shows the information regarding your research question or hypothesis. Furthermore, it shows what previous research has been done regarding the topic and what gap in the literature you want to fill in with your dissertation. 

Therefore there is no way you can escape writing the dissertation literature review. Additionally, it would be useful personally for you because it would help you to get the knowledge of the previous researchers on this topic and see the ways they conducted their own research. This will inspire you and make your writing process a few times easier.

Intricacies of Writing a Literature Review for a Dissertation

We have outlined that the literature review is important but let’s find out what insights it brings to the dissertation itself. When you writing the literature review you should take care of such important parts:

• Research: the first step you should do is to find the literature that you will include in your literature review. There is no way the relevant sources will appear in front of your eyes. So there is no simple way to find the literature. You need to review a lot of online libraries to find the literature that is suitable for the topic of your research. Additionally, you need to consider such important factors as the year of publication because some professors prefer the literature of the last 10 or 5 years to be included only. It means that you should not use the old literature of 15 or 20 years and only search for new journals or books. It can be easily done by setting a filter that will provide only the newest sources for you with a specific limit (of 5 or 10 years).
• Evaluation: you need to evaluate the main literature that you have gathered to support your dissertation. While many students think that the main goal of the literature review is to summarize the main points of the piece of literature, it is not always correct. A dissertation is an extensive scientific paper and you should rather express your opinion regarding the literature and evaluate it. You need to write whether you consider it reliable and think that the research provided there is advanced enough, is valuable for future research and has some implications.
• Relevance: you need to explain why the sources you have chosen for the literature review are relevant to your specific issue of research. You need to understand how the research in the literature gathered fills in the gap and contributes to the topic being researched. You should also draw connections about how the research in your own methodology and findings can be supported by the literature that you have chosen to include in the literature review.
• Formatting: you should also remember that the literature review requires formatting your literature in a specific style in which the whole dissertation is written. It means that you should cite the authors in a specific citation style. For example, if your dissertation is written in an APA style you should provide in-text citations of the same style and make sure it did not confuse styles. You can use the manuals if you have forgotten how to use a specific citation style. You can find manuals for different citation styles here .

We have described to you the difficulties you may face when you need to write the literature review for a dissertation and the steps you would need to go through to make the dissertation valid. However, we can give you a little advice on how to make this process easier, namely by using specialized websites that can help you with writing the literature review.
