A research synopsis describes the plan for your research project and is typically submitted to professors or department heads so they can approve your project. Most synopses are between 3,000 and 4,000 words and provide your research objectives and methods. While the specific types of information you need to include in your synopsis may vary depending on your department guidelines, most synopses include the same basic sections. In this article, we’ll walk you step-by-step through everything you need to know to write a synopsis for research.

Things You Should Know

• Begin your research synopsis by introducing the question your research will answer and its importance to your field.
• List 2 or 3 specific objectives you hope to achieve and how they will advance your field.
• Discuss your methodology to demonstrate why the study design you chose is appropriate for your research question.

Organizing Your Research Synopsis

• Find out what citation format you’re supposed to use, as well as whether you’re expected to use parenthetical references or footnotes in the body of your synopsis.
• If you have questions about anything in your guidelines, ask your instructor or advisor to ensure you follow them correctly.

• Title: the title of your study
• Abstract: a summary of your research synopsis
• Introduction: identifies and describes your research question
• Literature Review: a review of existing relevant research
• Objectives: goals you hope to accomplish through your study
• Hypotheses: results you expect to find through your research
• Methodology and methods: explains the methods you’ll use to complete your study
• References: a list of any references used in citations

Tip: Your synopsis might have additional sections, depending on your discipline and the type of research you're conducting. Talk to your instructor or advisor about which sections are required for your department.

• Keep in mind that you might not end up using all the sources you initially found. After you've finished your synopsis, go back and delete the ones you didn't use.

Writing Your Research Synopsis

• Your title should be a brief and specific reflection of the main objectives of your study. In general, it should be under 50 words and should avoid unneeded phrases like “an investigation into.”
• On the other hand, avoid a title that’s too short, as well. For example, a title like “A Study of Urban Heating” is too short and doesn’t provide any insight into the specifics of your research.

• The introduction allows you to explain to your reader exactly why the question you’re trying to answer is vital and how your knowledge and experience make you the best researcher to tackle it.
• Support most of the statements in your introduction with other studies in the area that support the importance of your question. For example, you might cite a previous study that mentions your problem as an area where further research needs to be done.
• The length of your introduction will vary depending on the overall length of your synopsis as well as the ultimate length of your eventual paper after you’ve finished your research. Generally, it will cover the first page or two of your synopsis.

• For example, try finding relevant literature through educational journals or bulletins from organizations like WHO and CDC.
• Typically, a thorough literature review discusses 8 to 10 previous studies related to your research problem.
• As with the introduction, the length of your literature review will vary depending on the overall length of your synopsis. Generally, it will be about the same length as your introduction.
• Try to use the most current research available and avoid sources over 5 years old.

• For example, an objective for research on urban heating could be “to compare urban heat modification caused by vegetation of mixed species considering the 5 most common urban trees in an area.”
• Generally, the overall objective doesn’t relate to solving a specific problem or answering a specific question. Rather, it describes how your particular project will advance your field.
• For specific objectives, think in terms of action verbs like “quantify” or “compare.” Here, you’re hoping to gain a better understanding of associations between particular variables.

• Specify the sources you used and the reasons you have arrived at your hypotheses. Typically, these will come from prior studies that have shown similar relationships.
• For example, suppose a prior study showed that children who were home-schooled were less likely to be in fraternities or sororities in college. You might use that study to back up a hypothesis that home-schooled children are more independent and less likely to need strong friendship support networks.

• Expect your methodology to be at least as long as either your introduction or your literature review, if not longer. Include enough detail that your reader can fully understand how you’re going to carry out your study.
• This section of your synopsis may include information about how you plan to collect and analyze your data, the overall design of your study, and your sampling methods, if necessary. Include information about the study setting, like the facilities and equipment that are available to you to carry out your study.
• For example, your research work may take place in a hospital, and you may use cluster sampling to gather data.

• Use between 100 and 200 words to give your readers a basic understanding of your research project.
• Include a clear statement of the problem, the main goals or objectives of your study, the theories or conceptual framework your research relies upon, and the methods you’ll use to reach your goals or objectives.

Tip: Jot down a few notes as you draft your other sections that you can compile for your abstract to keep your writing more efficient.

Reviewing and Editing Your Research Synopsis

• If you don’t have that kind of time because you’re up against a deadline, at least take a few hours away from your synopsis before you go back to edit it. Do something entirely unrelated to your research, like taking a walk or going to a movie.

• Eliminate sentences that don’t add any new information. Even the longest synopsis is a brief document—make sure every word needs to be there and counts for something.
• Get rid of jargon and terms of art in your field that could be better explained in plain language. Even though your likely readers are people who are well-versed in your field, providing plain language descriptions shows you know what you’re talking about. Using jargon can seem like you’re trying to sound like you know more than you actually do.

Tip: Free apps, such as Grammarly and Hemingway App, can help you identify grammatical errors as well as areas where your writing could be clearer. However, you shouldn't rely solely on apps since they can miss things.

• Reference list formatting is very particular. Read your references out loud, with the punctuation and spacing, to pick up on errors you wouldn’t have noticed if you’d just read over them.
• Compare your format to the one in the stylebook you’re using and make sure all of your entries are correct.

• Read your synopsis backward by starting on the last word and reading each word separately from the last to the first. This helps isolate spelling errors. Reading backward sentence by sentence helps you isolate grammatical errors without being distracted by the content.
• Print your synopsis and circle every punctuation mark with a red pen. Then, go through them and focus on whether they’re correct.
• Read your synopsis out loud, including the punctuation, as though you were dictating the synopsis.

• Have at least one person who isn’t familiar with your area of study look over your synopsis. If they can understand your project, you know your writing is clear. If any parts confuse them, then that’s an area where you can improve the clarity of your writing.

Expert Q&A

• If you make significant changes to your synopsis after your first or second round of editing, you may need to proofread it again to make sure you didn’t introduce any new errors. Thanks Helpful 0 Not Helpful 0

How to Write a Great Synopsis for Thesis

A synopsis is a structured outline of a research thesis and the steps followed to answer the research question. The goal of writing a synopsis is to clearly and thoroughly explain the need to investigate a certain problem using particular practical methods to conduct the study. One of the main components of this written work is an extensive literature review containing strong evidence that the proposed research is feasible.

Establishing the Background

A supervisor may ask you to write a synopsis for one or more reasons:

• to help you improve your critical thinking and writing skills
• to help you understand how to design a comprehensive synopsis
• to encourage you to write a comprehensive literature review to make sure that the research problem has not been answered yet
• to make you conduct a logical analysis of the steps that should be followed to meet the objectives of the research

A synopsis should be coherent in terms of research design. Thus, you should ensure that the research problem, aims, and research methods are logically linked and well-considered. Note that all synopses should contain answers for several crucial questions:

• Why should research on the proposed problem be undertaken?
• What is expected to be achieved?
• What has been done by other researchers on the proposed topic?
• How will the objectives of the study be achieved?

The Writing Process

Before proceeding, consider answering the following questions:

• Why am I going to study this topic?
• Why do I consider it to be important?
• Have I conducted an extensive literature review on the topic?
• What problem will the research help to solve?
• How do I incorporate previous studies on the topic?

The structure of a synopsis should correspond to the structure of qualifying research work, and the word count should be 2,500–3,000 words (Balu 38). The basic elements of a synopsis include a title page, contents page, an introduction, background, literature review, objectives, methods, experiments and results, conclusions, and references.

Introduction

As this comprises the first part of the main text, the introduction should convince readers that the study addresses a relevant topic and that the expected outcomes will provide important insights. Also, this section should include a brief description of the methods that will be used to answer the research question. Usually, the introduction is written in 1–3 paragraphs and answers the following questions:

• What is the topic of the research?
• What is the research problem that needs to be meaningfully understood or investigated?
• Why is the problem important?
• How will the problem be studied?

In this section, you should set the scene and better introduce the research topic by proving its scientific legitimacy and relevance. It is important to establish a clear focus and avoid broad generalizations and vague statements. If necessary, you may explain key concepts or terms. Consider covering the following points in this section:

• Discuss how the research will contribute to the existing scientific knowledge.
• Provide a detailed description of the research problem and purpose of the research.
• Provide a rationale for the study.
• Explain how the research question will be answered.
• Be sure to discuss the methods chosen and anticipated implications of the research.

Literature Review

A review of existing literature is an important part of a synopsis, as it:

• gives a more detailed look at scientific information related to the topic
• familiarizes readers with research conducted by others on a similar subject
• gives insight into the difficulties faced by other researchers
• helps identify variables for the research based on similar studies
• helps double-check the feasibility of the research problem.

When writing the literature review, do not simply present a list of methods researchers have used and conclusions they have drawn. It is important to compare and contrast different opinions and be unafraid to criticize some of them. Pay attention to controversial issues and divergent approaches used to address similar problems. You may discuss which arguments are more persuasive and which methods and techniques seem to be more valid and reliable. In this section, you are expected not to summarize but analyze the previous research while remembering to link it to your own purpose.

Identify the objectives of the research based on the literature review. Provide an overall objective related to the scientific contribution of the study to the subject area. Also include a specific objective that can be measured at the end of the research.

When writing this section, consider that the aim of the research is to produce new knowledge regarding the topic chosen. Therefore, the research methodology forms the core of your project, and your goal is to convince readers that the research design and methods chosen will rationally answer the research questions and provide effective tools to interpret the results correctly. It may be appropriate to incorporate some examples from your literature review into the description of the overall research design.

When describing the research methodology, ensure that you specify the approaches and techniques that will be used to answer the research question. In addition, be specific about applying the chosen methods and what you expect to achieve. Keep in mind that the methods section allows readers to evaluate the validity and feasibility of the study. Therefore, be sure to explain your decision to adopt specific methods and procedures. It is also important to discuss the anticipated barriers and limitations of the study and how they will be addressed. Specify what kind of contribution to the existing knowledge on the topic is expected, and discuss any ethical considerations that are relevant to the research.

Experiments and Results

Logically present and analyze the results of the study using tables or figures.

In this section, you should again state the significance of the research and summarize the study. Be sure to mention the study objectives and methods used to answer the research questions. Also, discuss how the results of the study contribute to the current knowledge on the problem.

A synopsis should contain a list of all references used. Make sure the references are formatted according to the chosen citation style and each source presented in this section is mentioned within the body of the synopsis.

The purpose of writing a synopsis is to show a supervisor a clear picture of a proposed project and allow him or her to find any gaps that have not been considered previously. A concisely written synopsis will help you gain approval to proceed with the actual research. While no rigid rules for writing this type of paper have been established, a synopsis should be constructed in a manner to help a supervisor understand the proposed research at first glance.

Lesson 4: Synopsis

In order to clarify your thoughts about the purpose of your thesis and how you plan to reach your research goals, you should prepare a synopsis. A synopsis is a short, systematic outline of your proposed thesis, made in preparation for your first meeting with your supervisor. It serves to ensure that your supervisor gets a clear picture of your proposed project and allows him or her to spot whether there are gaps or things that you have not taken into account.

Your synopsis will work as a kind of protocol for the further steps you need to take to ensure that your thesis reaches the required academic level – and that you finish on time.

Although there are no rigid rules for how a synopsis should look, it must contain:

• Rationale – should address the gaps/problems/issues observed as part of the background section and thus present the argument/justification for completing the study – as described in the lesson of the same name.
• Problem  formulation – the problem you aim to address in your thesis,as described in the lesson of the same name.
• Overall and specific objectives – the actions to be taken in order to address the problem, as described in the lesson of the same name.
• Method outline: What type of study is best suited to support the actions stated in the specific objectives? What kind of data (qualitative, quantitative) will your study require? What is your geographical study area and who is your target group(s)? Are there ethical considerations you have to make? Etc.
• Time plan: In the beginning, a rough timeline showing a plan on how your work will be divided over time. When is your deadline for e.g. literature search, potential fieldwork (e.g. interviews and/or questionnaire administration), data analysis, writing and layout? Once your problem formulation and objectives are approved by your supervisor, all details should be added to your time plan.
• References : Create a short list of the major references on which your rationale is based. Make sure that your in-text citations and reference list are completed correctly, both in support of your subsequent work, but also to demonstrate that you have a serious, scientific and methodical approach to your work. See how to use references correctly in the lesson of the same name in the module: Writing process.

At the beginning of your thesis period, your synopsis will be limited in scope and detail, but as you work your way deeper into your topic and you get a clearer picture of your objectives, methods and references, the more complete and detailed your synopsis will become.

A rule of thumb is that the length of your synopsis can vary from two to five pages, but the precise length and exact requirements of your synopsis can vary from institute to institute and from supervisor to supervisor.

Most study programmes will require that you present a final synopsis before starting data collection. However, the first version of your synopsis for discussion with your supervisor should not be an informal draft. Carefully performed work creates respect and motivation and saves a lot of you and your supervisor’s time.

A good approach from the very beginning is to establish a practice of how to write headings, references, names of species, etc. And be consistent. This will help you save time and importantly, lead to a better overall assessment of your final work.

How to Write a Good Synopsis for Thesis

After countless hours studying, hundreds of exams and tests, millions of words written in essays and projects, here you are at the final boss of your PhD or MBA program; your thesis. This is what stands between you and your degree and nothing may be more daunting a task than this one. Luckily for you, there are several ways of attacking this, and one of the major steps in doing so is writing a clear and effective synopsis for your thesis.

For those of you unfamiliar or wanting to know more, a thesis is a scholarly essay based upon your own personal research on a topic you have discovered or learned about during your time at school. In order to receive a Master’s degree or a PhD, a thesis is required, as it proves that you have critical thinking skills about your area of expertise and can prove your thesis through the research you have done. This is what separates you from the rest, your professors will see all the work you have done and the knowledge you have acquired throughout your journey to this point. 

What is a Synopsis?

Generally speaking, a synopsis is a general discussion or survey of a piece of work, explaining only the essential information in an easy, readable way. The function is to explain the main idea before a reader begins to read the thesis. Beyond that, a synopsis for a thesis has more function and importance than just a brief summary. 

The synopsis first of all, is not so brief. It gives a detailed description of your thesis, including the purpose of your research and methods you used as well as the process you used to explore the topic in depth. It introduces your thesis in a way that your readers know what to expect, but still surprised at the amount of work and detail presented within. 

This helps your supervisor see the possible strengths and weaknesses of your thesis and can give you helpful ideas on how to fill in those gaps. It’s a protocol used by your supervisor to ensure that you are on the right track to completing your thesis and you’ll finish on time. This is an essential step before writing your actual thesis. Make sure you complete your synopsis before you begin your research, as you may not need all the information you think you need. 

So, what makes a good Synopsis?

A good synopsis details everything related to your topic, but a great synopsis ensures that not only is the content there, but it is presented in a logical manner and easy to follow. Your outlined thesis should include the following:

• The title of the topic 
• The abstract 
• The necessity of the topic – the background 
• All related literature concerning the topic 
• Methods and Materials of your research

Once these headings are established, it helps you to go through each stage, making sure that no information is left off or missed. The scope of your thesis is broad, but has a direction. As you progress through your synopsis, the details fall into place and allows you to start doing your research and collecting your data. 

Establish your background

Your loose thoughts should be filtered and sorted and should be organized based on how they are all linked together. The aims and goals of your topic should be apparent, so make sure to ask yourself these questions:

“Why should someone research this topic” “What are my expectations of this topic” “What have others contributed to the research of this topic” “How will I reach the goals and objectives of my topic”

Once the background is established, you can start thinking about the actual content.

Identify your Objectives

The background can help you decide the main reasons why you are undergoing this research into this topic. What good will this do for the world? What good will this do for professionals in this field? What good will it do for the communities surrounding this field? Having a measurable objective will pave the way to a better thesis. 

Consider your Methods 

The aim of the thesis is to provide novel information about your topic, something original or groundbreaking. This is important as it gives the reader something to analyze and think about. The way you deliver your information should provoke thoughts, or leave a trail to be followed into a thought process. Your approach should be able to answer any and all questions regarding your thesis, whether or not your ideas hold validity and some substance. Explaining your decisions and thought processes are much easier if you set your boundaries and barriers that you can address in your synopsis. 

Present your Experiments and Analysis

This is an important step once everything else has been established. Detail the research you will do and the experiments you will be observing and analyze them in detail. You should link the results to your findings and your knowledge about the topic. This is where you earn your money, the way you can tie in numbers and facts to the knowledge you already know to solidify your thesis. The better your analysis is, the more your reader will understand. 

Conclude and Summarize

Your supervisor should have already read your synopsis up to this point and understood the concept and scope of your thesis. But you should reiterate your main idea in case your supervisor got lost or that you had a different idea than they had. Once you’ve summed it up, your supervisor can give you helpful hints and tips to solidify the rest of your thesis and smooth out the potential problems or holes in your thesis. 

So, what now?

Begin writing your synopsis with these key facts in mind. Know that your synopsis is a tool for you to organize your thoughts and for your supervisor to advise you on your direction and objectives. Be concise and be knowledgeable, so that you may get the best possible feedback on your synopsis.

A synopsis is a brief summary which gives readers an overview of the main points. In an academic context, this is usually a summary of a text (a journal article, book, report etc) but in some instances you might be writing a synopsis of a talk, film or other form of presentation. A synopsis is a neutral summary, objectively capturing the main points, rather than your own perspective or critique, and it focusses directly on the text you’re summarising rather than being a wider discussion of a topic, as an essay might be.

A synopsis aims to give the reader a full, if brief, account of the whole text so that they can follow its main points without having to read it themselves. It’s not a ‘trailer’ designed to tempt your audience to read the text itself, so you don’t have to worry about ‘hooking’ them in with hints and high points or ‘spoiling the ending’ - give the whole text equal coverage, including the conclusions. You could add some commentary which gives the reader a bit of context about the text, including the authors and circumstances it was written in (for example, if it is part of a debate, particular school of thought or its significance and what impact it’s had).

Writing a good synopsis is a skill, and there are a number of challenges: 

• Separating the main points from the minor detail
• Knowing what to leave out as well as what to include
• Giving a sense of the overall narrative as well as listing the key points
• Covering the whole text within a small word limit
• Knowing how closely to stick to the original, especially in terms of the wording
• Whether to give all key points equal treatment, or cover some more briefly, even combining them
• Rephrasing things concisely without losing the meaning or misrepresenting it
• Not leaving out anything crucial to understanding the whole overall message

A good synopsis will allow the reader to feel as if they’d skimread the whole text themselves, understanding the overall gist and highlighting what they need to know. A poor synopsis will get bogged down in detail, giving a confused account of the whole story by just listing points, miss out major points or give an inaccurate or one-sided account or stick so closely to the original that it becomes plagiarism without demonstrating a real understanding by the person summarising it.  

How to prepare a synopsis

Boiling down the key points and overall narrative of the original means good reading and note-taking skills which aim to identify and boil down key points to their essence. You could try some of the following approaches: 

• Read the whole text, and afterwards, without re-reading, jot down your first initial summary in 50 words to capture its overall point. You can check it back for accuracy or anything you left out, but stick within ca 50 words
• Read the introduction and first line of each paragraph to get a sense of the overall structure and key points within it
• Highlight one sentence in each paragraph that you think is essential detail to understanding that section
• Alternatively, with a marker pen, cross out anything that isn’t essential to an understanding of the whole section or text 
• Jot down only key words as a summary of each point rather than whole sentences
• Read each paragraph and summarise it without looking, in one sentence of your own 
• Consider how many points you can make within your word count, and reduce or combine your list of summarised points down to this number

You could start small, identifying just keywords or sentences at first and then work them up into phrases, bullet points and sentences as a rough plan or draft, or you could start big with the original text and reduce each section, paragraph and sentence summary again and again until you have boiled it down to its essence.  

When you start to prepare your first plan or draft, try to use your notes or memory and step away from the original as much as you can. You can go back and check it afterwards, but you need to create some distance to be able to create your own account and have confidence in the points you have identified as essential.

Writing a synopsis

The main decisions facing you as you write up your summary are about how closely to stick to the original in terms of structure and style, and how much attention to give to each point. 

• You could begin your synopsis with a brief context, explaining who the authors are, the context and significance of their work, as well as anything you think might help the reader to understand the following summary
• The most common structure is to follow that of the original text, to give a sense of its narrative flow as well as the key points within it. You could choose to depart from it a little though, perhaps glossing over some points faster than others, combining two sections which go together or aren’t enough in their own right, possibly even changing the order a little where it helps to combine two similar points. Careful use of signposting language will help the reader clearly follow the structure (and note anywhere you’ve changed it from the original) so they can identify the bit you’re talking about in the original if they want to
• The style will naturally be strongly influenced by the original wording, but you should phrase it in your own words wherever possible. It’s harder to nibble away words from a much longer original than it is to start again and use your own concise phrasing, and you want to demonstrate your own understanding to the reader. You could use the odd original phrase or quotation here or there, but the synopsis needs to be more than a collage of quotations; it’s a thing in its own right rather than a cut-down version of the original
• You can also show your own response to the text in the way you use language to guide the reader to what you feel are the key points and (briefly) why. Your own voice doesn’t need to be very obvious in the synopsis, as it’s about the text rather than your reaction to it, but you have made analytical decisions about what is important, and might want to explain to the reader why these points are significant in understanding the whole
• What is the main purpose of this text? What did it aim to discover, explain or prove?
• Why was this research done? How significant is it?
• How was the research conducted? What kind of research is it?
• What were the three (or four, five) main things I should be aware of from this paper?
• What is their line of argument?
• What is their overall conclusion, recommendation, finding? Why is that important?

Managing word count

The trick to writing a concise synopsis which keeps within your word limit is not to start from the much bigger original text, but from your own boiled down notes. If you’re over the word count, you could start cutting out words that don’t seem essential, but if you go too far, you end up with a text which does not read well and doesn’t hang together. It might be better to remove whole sentences and perhaps whole points, than nibble away at words here and there.

How to write Dissertation and synopsis

What is the importance of your research?

Which type of problem your dissertation is going to challenge or raise?

Why is it a problem for the research, academic, scientific, technical, the management, or legal community?

Why is it important for you to find a solution?

How are you going to search for the answers?

A step before the Dissertation - How to write a synopsis

Dissertation topic - The topic is the most important thing for research which should be selected wisely, e.g.:-

It should be specific, unambiguous, and explicit.

It should not be vague or prolonged.

It should be about the general, legal, informative, or technical issues at the national or international level.

Introduction - It should provide a brief description of the area of the proposed research work in a very concrete, concise, and accurate manner. It must be clear rather than fuzzy and general.

Review of Literature – The meaning of ‘Research’ is ‘to search again’. That’s why ‘review of the literature’ is an essential and very important part of any research work, which explicit the research work was done previously in the same area of the proposed research. It is essential to plan further research efficiently and in an appropriate manner. The information given in the review should be supported by references.

Objectives of research - There must be comprehensive objectives of the research work. These objectives will indicate the aim, major aspects, and the overall purpose of the study. It should be clearly and concisely defined. These are broad statements of desired outcomes, or the general intentions of the research, which 'paint a picture' of your research work. The maximum aim or objectives should be up to three. If should not be too extensive. Make accurate use of concepts, which must be sensible and precisely described.

Justification of the problem - Every objective needs justification. In research, it is essential to justify your objective in a concrete and impressive and remarkable manner. You may take help from the previous research work, cases, reports, etc. There is a possibility to predict the specific and general benefits likely to be achieved as a result of the completion of the proposed research by making comparisons and citing references of the previous works.

The hypothesis of Study- Hypothesis is a statement that is to be tested for possible acceptance or rejection. Hypothesis are of two types i.e.:-

Null (Ho) - Null hypothesis is tested for possible rejection.

Alternative (H1)., which is tested for possible acceptance.

Significance of Study - It emphasized the significance/ importance of the research work/study i.e. reason and aim of the selection of the topic of research.

Statement of Problem - The researcher has to clearly identify the problem/issue selected for the thesis/ dissertation.

Research Methodology - It means a plan of work describing the various aspects of the study in a logical sequence along with the methodologies to be employed. It helps to validate that the researcher has a fairly good idea about the nature of work likely to be involved. The methodology includes the following:-

Sources of data : Factual information is called quantitative data. Information collected about opinions and views is called qualitative data. There are two methods for this:

Primary research (field research) involves gathering new data that has not been collected before. For e.g., surveys using questionnaires or interviews with groups of people in a focus group and observations.

Secondary research (desk research) involves gathering existing data that has already been produced. For example, researching the newspapers and company reports, case studies, diaries, critical incidents, portfolios, books, journals, periodicals, abstracts, indexes, directories, research reports, conference papers, market reports, annual reports, internal records of organizations, newspapers & magazines, CD-ROMs, on-line databases, Internet, videos & broadcasts.

References and Bibliography - Synopsis should contain at the end a list of references and a bibliography if required. These should be written on a standard pattern.

Length of a synopsis - It will be difficult to define an overall length for a synopsis for legal research in such varied fields of study. However, it should be concise as far as possible and avoid repetitions. The total length of a synopsis may run from 1500 to a few thousand words.

What Is A Literature Review?

A plain-language explainer (with examples).

By:  Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)

If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.

Literature Review 101

• What (exactly) is a literature review
• What’s the purpose of the literature review chapter
• How to find high-quality resources
• How to structure your literature review chapter
• Example of an actual literature review

What is a literature review?

The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of  reviewing the literature  – i.e. sourcing and reading through the existing research relating to your research topic. The second is the  actual chapter  that you write up in your dissertation, thesis or research project. Let’s look at each of them:

Reviewing the literature

The first step of any literature review is to hunt down and  read through the existing research  that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then  summarise and catalogue these  for easy reference when you write up your literature review chapter. 

The literature review chapter

The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an  overview of the key literature  that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an  integrated review of the state of knowledge  around your research topic. 

What’s the purpose of a literature review?

The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:

Purpose #1 – Demonstrate your topic knowledge

The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you  know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be  more than just a summary  of who said what – it needs to integrate the existing research to  show how it all fits together  and what’s missing (which leads us to purpose #2, next). 

Purpose #2 – Reveal the research gap that you’ll fill

The second function of the literature review chapter is to  show what’s currently missing  from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that  your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.  

Purpose #3 – Lay the foundation for your conceptual framework

The third function of the literature review is to form the  basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review. 

For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut! 

So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework. 

Purpose #4 – To inform your methodology

The fourth function of the literature review is to  inform the choice of methodology  for your own research. As we’ve  discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.

So, when you’re reviewing the literature, you’ll need to  pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to  “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales. 

How do I find articles for my literature review?

Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is  built on credible research . 

We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the  most popular pieces of research  are in your field.

One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes  it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites. 

Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to  ResearchGate , which is another great source for existing research. 

Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer. 

Need a helping hand?

How should I structure my literature review?

Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.

You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.

In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .

Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.

Example of a literature review

In the video below, we walk you through a high-quality literature review from a dissertation that earned full distinction. This will give you a clearer view of what a strong literature review looks like in practice and hopefully provide some inspiration for your own. 

Wrapping Up

In this post, we’ve (hopefully) answered the question, “ what is a literature review? “. We’ve also considered the purpose and functions of the literature review, as well as how to find literature and how to structure the literature review chapter. If you’re keen to learn more, check out the literature review section of the Grad Coach blog , as well as our detailed video post covering how to write a literature review .

How to Write a Thesis or Dissertation Introduction

Published on 9 September 2022 by Tegan George and Shona McCombes.

The introduction is the first section of your thesis or dissertation , appearing right after the table of contents . Your introduction draws your reader in, setting the stage for your research with a clear focus, purpose, and direction.

Your introduction should include:

• Your topic, in context: what does your reader need to know to understand your thesis dissertation?
• Your focus and scope: what specific aspect of the topic will you address?
• The relevance of your research: how does your work fit into existing studies on your topic?
• Your questions and objectives: what does your research aim to find out, and how?
• An overview of your structure: what does each section contribute to the overall aim?

Table of contents

How to start your introduction, topic and context, focus and scope, relevance and importance, questions and objectives, overview of the structure, thesis introduction example, introduction checklist, frequently asked questions about introductions.

Although your introduction kicks off your dissertation, it doesn’t have to be the first thing you write – in fact, it’s often one of the very last parts to be completed (just before your abstract ).

It’s a good idea to write a rough draft of your introduction as you begin your research, to help guide you. If you wrote a research proposal , consider using this as a template, as it contains many of the same elements. However, be sure to revise your introduction throughout the writing process, making sure it matches the content of your ensuing sections.

The only proofreading tool specialized in correcting academic writing

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

Begin by introducing your research topic and giving any necessary background information. It’s important to contextualise your research and generate interest. Aim to show why your topic is timely or important. You may want to mention a relevant news item, academic debate, or practical problem.

After a brief introduction to your general area of interest, narrow your focus and define the scope of your research.

You can narrow this down in many ways, such as by:

• Geographical area
• Time period
• Demographics or communities
• Themes or aspects of the topic

It’s essential to share your motivation for doing this research, as well as how it relates to existing work on your topic. Further, you should also mention what new insights you expect it will contribute.

Start by giving a brief overview of the current state of research. You should definitely cite the most relevant literature, but remember that you will conduct a more in-depth survey of relevant sources in the literature review section, so there’s no need to go too in-depth in the introduction.

Depending on your field, the importance of your research might focus on its practical application (e.g., in policy or management) or on advancing scholarly understanding of the topic (e.g., by developing theories or adding new empirical data). In many cases, it will do both.

Ultimately, your introduction should explain how your thesis or dissertation:

• Helps solve a practical or theoretical problem
• Addresses a gap in the literature
• Builds on existing research
• Proposes a new understanding of your topic

Prevent plagiarism, run a free check.

Perhaps the most important part of your introduction is your questions and objectives, as it sets up the expectations for the rest of your thesis or dissertation. How you formulate your research questions and research objectives will depend on your discipline, topic, and focus, but you should always clearly state the central aim of your research.

If your research aims to test hypotheses , you can formulate them here. Your introduction is also a good place for a conceptual framework that suggests relationships between variables .

• Conduct surveys to collect data on students’ levels of knowledge, understanding, and positive/negative perceptions of government policy.
• Determine whether attitudes to climate policy are associated with variables such as age, gender, region, and social class.
• Conduct interviews to gain qualitative insights into students’ perspectives and actions in relation to climate policy.

To help guide your reader, end your introduction with an outline  of the structure of the thesis or dissertation to follow. Share a brief summary of each chapter, clearly showing how each contributes to your central aims. However, be careful to keep this overview concise: 1-2 sentences should be enough.

I. Introduction

Human language consists of a set of vowels and consonants which are combined to form words. During the speech production process, thoughts are converted into spoken utterances to convey a message. The appropriate words and their meanings are selected in the mental lexicon (Dell & Burger, 1997). This pre-verbal message is then grammatically coded, during which a syntactic representation of the utterance is built.

Speech, language, and voice disorders affect the vocal cords, nerves, muscles, and brain structures, which result in a distorted language reception or speech production (Sataloff & Hawkshaw, 2014). The symptoms vary from adding superfluous words and taking pauses to hoarseness of the voice, depending on the type of disorder (Dodd, 2005). However, distortions of the speech may also occur as a result of a disease that seems unrelated to speech, such as multiple sclerosis or chronic obstructive pulmonary disease.

This study aims to determine which acoustic parameters are suitable for the automatic detection of exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD) by investigating which aspects of speech differ between COPD patients and healthy speakers and which aspects differ between COPD patients in exacerbation and stable COPD patients.

Checklist: Introduction

I have introduced my research topic in an engaging way.

I have provided necessary context to help the reader understand my topic.

I have clearly specified the focus of my research.

I have shown the relevance and importance of the dissertation topic .

I have clearly stated the problem or question that my research addresses.

I have outlined the specific objectives of the research .

I have provided an overview of the dissertation’s structure .

You've written a strong introduction for your thesis or dissertation. Use the other checklists to continue improving your dissertation.

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem
• A thesis statement or research question
• Sometimes an outline of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

Research objectives describe what you intend your research project to accomplish.

They summarise the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

What Is a Dissertation Synopsis?

From time to time you should enlarge your knowledge. Everyone try to achieve positive results in his/her own way. If you want to succeed in writing your dissertation, it is high time to write a good dissertation synopsis .

The main purpose of any dissertation synopsis is to present the major information on a work. When you write your dissertation synopsis, you should think about the way of making it understandable for your readers.

Dissertation synopsis – Structure

Of course, it is very important to be logical while writing your dissertation synopsis. You choose a certain structure and present the information according to its parts. So, all ideas should be logically connected. You should write an interesting introduction, where you point out the most important information. Then, you should develop your ideas in the main body. You cannot stop your dissertation synopsis writing without a logical ending. So, make a smart conclusion.

Dissertation synopsis – Size

Your dissertation synopsis is a brief presentation of your dissertation. With the help of a dissertation synopsis, your tutor will estimate your abilities to speak up to the point and be precise and clear. You should pay attention to writing your dissertation synopsis , since the shorter your dissertation synopsis is, the harder it will be to express all your thoughts and ideas. Your dissertation synopsis should be around 2000-3000 words. This is the most appropriate for your dissertation synopsis size.

Dissertation synopsis – Style

In your dissertation synopsis you should keep to one and the same style, which you have chosen for your dissertation. If it is a scientific dissertation, so be scientific in your dissertation synopsis. Of course, you should not overload your dissertation synopsis with too complicated scientific terms. Also, you should remember that your dissertation synopsis is a kind of presentation of your work. So, a bit of interesting expressions and patchwords will be okay.

Tips and Resources for a Successful Summer of Dissertation Writing

By Yana Zlochistaya

Summer can be a strange time for graduate students. Gone are the seminars and workshops, the student clubs, and the working group, that structured the semester and provided us with a sense of community. Instead, we’re faced with a three-month expanse of time that can feel equal parts liberating and intimidating. This double-edged freedom is only exacerbated for those of us in the writing stage of our dissertation, when isolation and a lack of discipline can have a particularly big impact. For those hoping not to enter another summer with lofty plans, only to blink and find ourselves in August disappointed with our progress, we’ve compiled some tips and resources that can help.

According to Graduate Writing Center Director Sabrina Soracco, the most important thing you can do to set yourself up for writing success is to clarify your goals. She recommends starting this process by looking at departmental requirements for a completed dissertation. Consider when you would like to file and work backwards from that point, determining what you have to get done in order to hit that target. Next, check in with your dissertation committee members to set up an accountability structure. Would they prefer an end-of-summer update to the whole committee? A monthly check-in with your chair or one of your readers? Setting up explicit expectations that work for you and your committee can cut through the aimlessness that comes with a major writing project.

For those early on in their dissertation-writing process, a committee meeting is also a valuable opportunity to set parameters. “One of the problems with the excitement for the discipline that happens post-quals is that it results in too many ideas,” says Director Soracco. Your committee members should give you input on productive research directions so that you can begin to hone in on your project. It is also important to remember that your dissertation does not have to be the end-all-and-be-all of your academic research. Ideas that do not fit into its scope can end up becoming conference papers or even book chapters.

Once you have a clear goal that you have discussed with your committee, the hard part begins: you have to actually write. The Graduate Writing Center offers several resources to make that process easier:

• The Graduate Writing Community. This is a totally remote, two-month program that is based on a model of “gentle accountability.” When you sign up, you are added to a bCourses site moderated by a Graduate Writing Consultant. At the beginning of the week, everyone sets their goals in a discussion post, and by the end of the week, everyone checks in with progress updates. During the week, the writing consultants offer nine hours of remote synchronous writing sessions. As a writing community member, you can attend whichever sessions work best for your schedule. All that’s required is that you show up, set a goal for that hour, and work towards that goal for the length of two 25-minute Pomodoro sessions . This year’s summer writing community will begin in June. Keep your eye on your email for the registration link!
• Writing Consultations : As a graduate student, you can sign up for an individual meeting with a Graduate Writing Consultant. They can give you feedback on your work, help you figure out the structure of a chapter, or just talk through how to get started on a writing project. 
• Independent Writing Groups: If you would prefer to write with specific friends or colleagues, you can contact Graduate Writing Center Director Sabrina Soracco at [email protected] so that she can help you set up your own writing group. The structure and length of these groups can differ; often, members will send each other one to five pages of writing weekly and meet the next day for two hours to provide feedback and get advice. Sometimes, groups will meet up not only to share writing, but to work in a common space before coming together to debrief. Regardless of what the groups look like, the important thing is to create a guilt-free space. Some weeks, you might submit an outline; other weeks, it might be the roughest of rough drafts; sometimes, you might come to a session without having submitted anything. As long as we continue to make progress (and show up even when we don’t), we’re doing what we need to. As Director Soracco puts it, “it often takes slogging through a lot of stuff to get to that great epiphany.”

Associated Data

A dissertation is a practical exercise that educates students about basics of research methodology, promotes scientific writing and encourages critical thinking. The National Medical Commission (India) regulations make assessment of a dissertation by a minimum of three examiners mandatory. The candidate can appear for the final examination only after acceptance of the dissertation. An important role in a dissertation is that of the guide who has to guide his protégés through the process. This manuscript aims to assist students and guides on the basics of conduct of a dissertation and writing the dissertation. For students who will ultimately become researchers, a dissertation serves as an early exercise. Even for people who may never do research after their degree, a dissertation will help them discern the merits of new treatment options available in literature for the benefit of their patients.

INTRODUCTION

The zenith of clinical residency is the completion of the Master's Dissertation, a document formulating the result of research conducted by the student under the guidance of a guide and presenting and publishing the research work. Writing a proper dissertation is most important to present the research findings in an acceptable format. It is also reviewed by the examiners to determine a part of the criteria for the candidate to pass the Masters’ Degree Examination.

The predominant role in a dissertation is that of the guide who has to mentor his protégés through the process by educating them on research methodology, by: (i) identifying a pertinent and topical research question, (ii) formulating the “type” of study and the study design, (iii) selecting the sample population, (iv) collecting and collating the research data accurately, (v) analysing the data, (vi) concluding the research by distilling the outcome, and last but not the least (vii) make the findings known by publication in an acceptable, peer-reviewed journal.[ 1 ] The co-guide could be a co-investigator from another department related to the study topic, and she/he will play an equivalent role in guiding the student.

Research is a creative and systematic work undertaken to increase the stock of knowledge.[ 2 ] This work, known as a study may be broadly classified into two groups in a clinical setting:

• Trials: Here the researcher intervenes to either prevent a disease or to treat it.
• Observational studies: Wherein the investigator makes no active intervention and merely observes the patients or subjects allocated the treatment based on clinical decisions.[ 3 ]

The research which is described in a dissertation needs to be presented under the following headings: Introduction, Aim of the Study, Description of devices if any or pharmacology of drugs, Review of Literature, Material and Methods, Observations and Results, Discussion, Conclusions, Limitations of the study, Bibliography, Proforma, Master chart. Some necessary certificates from the guide and the institute are a requirement in certain universities. The students often add an acknowledgement page before the details of their dissertation proper. It is their expression of gratitude to all of those who they feel have been directly or indirectly helpful in conduct of the study, data analysis, and finally construction of the dissertation.

Framing the research question (RQ)

It is the duty of the teacher to suggest suitable research topics to the residents, based on resources available, feasibility and ease of conduct at the centre. Using the FINER criteria, the acronym for feasibility, topical interest, novelty, ethicality and relevance would be an excellent way to create a correct RQ.[ 4 ]

The PICOT method which describes the patient, intervention, comparison, outcome and time, would help us narrow down to a specific and well-formulated RQ.[ 5 , 6 ] A good RQ leads to the derivation of a research hypothesis, which is an assumption or prediction of the outcome that will be tested by the research. The research topic could be chosen from among the routine clinical work regarding clinical management, use of drugs e.g., vasopressors to prevent hypotension or equipment such as high flow nasal oxygen to avoid ventilation.

Review of literature

To gather this information may be a difficult task for a fresh trainee however, a good review of the available literature is a tool to identify and narrow down a good RQ and generate a hypothesis. Literature sources could be primary (clinical trials, case reports), secondary (reviews, meta-analyses) or tertiary (e.g., reference books, compilations). Methods of searching literature could be manual (journals) or electronic (online databases), by looking up references or listed citations in existing articles. Electronic database searches are made through the various search engines available online e.g., scholar.google.com, National Library of Medicine (NLM) website, clinical key app and many more. Advanced searches options may help narrow down the search results to those that are relevant for the student. This could be based on synthesising keywords from the RQ, or by searching for phrases, Boolean operators, or utilising filters.

After choosing the topic, an apt and accurate title has to be chosen. This should be guided by the use of Medical Subject Headings (MeSH) terminology from the NLM, which is used for indexing, cataloguing, and searching of biomedical and health-related information.[ 7 ] The dissertation requires a detailed title which may include the objective of the study, key words and even the PICOT components. One may add the study design in the title e.g. “a randomised cross over study” or “an observational analytical study” etc.

Aim and the objectives

The Aims and the Objectives of the research study have to be listed clearly, before initiating the study.[ 8 ] “Gaps” or deficiencies in existing knowledge should be clearly cited. The Aim by definition is a statement of the expected outcome, while the Objectives (which might be further classed into primary and secondary based on importance) should be specific, measurable, achievable, realistic or relevant, time-bound and challenging; in short, “SMART!” To simplify, the aim is a statement of intent, in terms of what we hope to achieve at the end of the project. Objectives are specific, positive statements of measurable outcomes, and are a list of steps that will be taken to achieve the outcome.[ 9 ] Aim of a dissertation, for example, could be to know which of two nerve block techniques is better. To realise this aim, comparing the duration of postoperative analgesia after administration of the block by any measurable criteria, could be an objective, such as the time to use of first rescue analgesic drug. Similarly, total postoperative analgesic drug consumption may form a secondary outcome variable as it is also measurable. These will generate data that may be used for analysis to realise the main aim of the study.

Inclusion and exclusions

The important aspect to consider after detailing when and how the objectives will be measured is documenting the eligibility criteria for inclusion of participants. The exclusion criteria must be from among the included population/patients only. e.g., If only American Society of Anesthesiologists (ASA) I and II are included, then ASA III and IV cannot be considered as exclusion criteria, since they were never a part of the study. The protocol must also delineate the setting of the study, locations where data would be collected, and specify duration of conduct of the dissertation. A written informed consent after explaining the aim, objectives and methodology of the study is legally mandatory before embarking upon any human study. The study should explicitly clarify whether it is a retrospective or a prospective study, where the study is conducted and the duration of the study.

Sample size: The sample subjects in the study should be representative of the population upon whom the inference has to be drawn. Sampling is the process of selecting a group of representative people from a larger population and subjecting them for the research.[ 10 ] The sample size represents a number, beyond which the addition of population is unlikely to change the conclusion of the study. The sample size is calculated taking into consideration the primary outcome criteria, confidence interval (CI), power of the study, and the effect size the researcher wishes to observe in the primary objective of the study. Hence a typical sample size statement can be - “Assuming a duration of analgesia of 150 min and standard deviation (SD) of 15 min in first group, keeping power at 80% and CIs at 95% (alpha error at 0.05), a sample of 26 patients would be required to detect a minimum difference (effect size) of 30% in the duration of analgesia between the two groups. Information regarding the different sampling methods and sample size calculations may be found in the Supplementary file 1 .

Any one research question may be answered using a number of research designs.[ 11 ] Research designs are often described as either observational or experimental. The various research designs may be depicted graphically as shown in Figure 1 .

Graphical description of available research designs

The observational studies lack “the three cornerstones of experimentation” – controls, randomisation, and replication. In an experimental study on the other hand, in order to assess the effect of treatment intervention on a participant, it is important to compare it with subjects similar to each other but who have not been given the studied treatment. This group, also called the control group, may help distinguish the effect of the chosen intervention on outcomes from effects caused by other factors, such as the natural history of disease, placebo effects, or observer or patient expectations.

All the proposed dissertations must be submitted to the scientific committee for any suggestion regarding the correct methodology to be followed, before seeking ethical committee approval.

Ethical considerations

Ethical concerns are an important part of the research project, right from selection of the topic to the dissertation writing. It must be remembered, that the purpose of a dissertation given to a post-graduate student is to guide him/her through the process by educating them on the very basics of research methodology. It is therefore not imperative that the protégés undertake a complicated or risky project. If research involves human or animal subjects, drugs or procedures, research ethics guidelines as well as drug control approvals have to be obtained before tabling the proposal to the Institutional Ethics Committee (IEC). The roles, responsibilities and composition of the Ethics Committee has been specified by the Directorate General of Health Services, Government of India. Documented approval of the Ethics committee is mandatory before any subject can be enroled for any dissertation in India. Even retrospective studies require approval from the IEC. Details of this document is available at: https://cdsco.gov.in/opencms/resources/UploadCDSCOWeb/2018/UploadEthicsRegistration/Applmhrcrr.pdf .

The candidate and the guide are called to present their proposal before the committee. The ethical implications, risks and management, subjects’ rights and responsibilities, informed consent, monetary aspects, the research and analysis methods are all discussed. The patient safety is a topmost priority and any doubts of the ethical committee members should be explained in medically layman's terms. The dissertation topics should be listed as “Academic clinical trials” and must involve only those drugs which are already approved by the Drugs Controller General of India. More commonly, the Committee suggests rectifications, and then the researchers have to resubmit the modified proposal after incorporating the suggestions, at the next sitting of the committee or seek online approval, as required. At the conclusion of the research project, the ethics committee has to be updated with the findings and conclusions, as well as when it is submitted for publication. Any deviation from the approved timeline, as well as the research parameters has to be brought to the attention of the IEC immediately, and re-approval sought.

Clinical trial registration

Clinical Trial Registry of India (CTRI) is a free online searchable system for prospective registration of all clinical studies conducted in India. It is owned and managed by the National Institute of Medical Statistics, a division of Indian Council of Medical Research, Government of India. Registration of clinical trials will ensure transparency, accountability and accessibility of trials and their results to all potential beneficiaries.

After the dissertation proposal is passed by the scientific committee and IEC, it may be submitted for approval of trial registration to the CTRI. The student has to create a login at the CTRI website, and submit all the required data with the help of the guides. After submission, CTRI may ask for corrections, clarifications or changes. Subject enrolment and the actual trial should begin only after the CTRI approval.

Randomisation

In an experimental study design, the method of randomisation gives every subject an equal chance to get selected in any group by preventing bias. Primarily, three basic types employed in post-graduate medical dissertations are simple randomisation, block randomisation and stratified randomisation. Simple randomisation is based upon a single sequence of random assignments such as flipping a coin, rolling of dice (above 3 or below 3), shuffling of cards (odd or even) to allocate into two groups. Some students use a random number table found in books or use computer-generated random numbers. There are many random number generators, randomisation programs as well as randomisation services available online too. ( https://www-users.york.ac.uk/~mb55/guide/randsery.htm ).

There are many applications which generate random number sequences and a research student may use such computer-generated random numbers [ Figure 2 ]. Simple randomisation has higher chances of unequal distribution into the two groups, especially when sample sizes are low (<100) and thus block randomisation may be preferred. Details of how to do randomisation along with methods of allocation concealment may be found in Supplementary file 2 .

Allocation concealment

If it is important in a study to generate a random sequence of intervention, it is also important for this sequence to be concealed from all stake-holders to prevent any scope of bias.[ 12 ] Allocation concealment refers to the technique used to implement a random sequence for allocation of intervention, and not to generate it.[ 13 ] In an Indian post-graduate dissertation, the sequentially numbered, opaque, sealed envelopes (SNOSE) technique is commonly used [ Supplementary file 2 ].

To minimise the chances of differential treatment allocation or assessments of outcomes, it is important to blind as many individuals as possible in the trial. Blinding is not an all-or-none phenomenon. Thus, it is very desirable to explicitly state in the dissertation, which individuals were blinded, how they achieved blinding and whether they tested the success of blinding.

Commonly used terms for blinding are

• Single blinding: Masks the participants from knowing which intervention has been given.
• Double blinding: Blinds both the participants as well as researchers to the treatment allocation.
• Triple blinding: By withholding allocation information from the subjects, researchers, as well as data analysts. The specific roles of researchers involved in randomisation, allocation concealment and blinding should be stated clearly in the dissertation.

Data which can be measured as numbers are called quantitative data [ Table 1 ]. Studies which emphasise objective measurements to generate numerical data and then apply statistical and mathematical analysis constitute quantitative research. Qualitative research on the other hand focuses on understanding people's beliefs, experiences, attitudes, behaviours and thus these generate non-numerical data called qualitative data, also known as categorical data, descriptive data or frequency counts. Importance of differentiating data into qualitative and quantitative lies in the fact that statistical analysis as well as the graphical representation may be very different.

Data collection types

In order to obtain data from the outcome variable for the purpose of analysis, we need to design a study which would give us the most valid information. A valid data or measurement tool, is the degree to which the tool measures what it claims to measure. For example, appearance of end tidal carbon dioxide waveform is a more valid measurement to assess correct endotracheal tube placement than auscultation of breath sounds on chest inflation.

The compilation of all data in a ‘Master Chart’ is a necessary step for planning, facilitating and appropriate preparation and processing of the data for analysis. It is a complete set of raw research data arranged in a systematic manner forming a well-structured and formatted, computable data matrix/database of the research to facilitate data analysis. The master chart is prepared as a Microsoft Excel sheet with the appropriate number of columns depicting the variable parameters for each individual subjects/respondents enlisted in the rows.

Statistical analysis

The detailed statistical methodology applied to analyse the data must be stated in the text under the subheading of statistical analysis in the Methods section. The statistician should be involved in the study during the initial planning stage itself. Following four steps have to be addressed while planning, performing and text writing of the statistical analysis part in this section.

Step 1. How many study groups are present? Whether analysis is for an unpaired or paired situation? Whether the recorded data contains repeated measurements? Unpaired or paired situations decide again on the choice of a test. The latter describes before and after situations for collected data (e.g. Heart rate data ‘before’ and ‘after’ spinal anaesthesia for a single group). Further, data should be checked to find out whether they are from repeated measurements (e.g., Mean blood pressure at 0, 1 st , 2 nd , 5 th , 10 th minutes and so on) for a group. Different types of data are commonly encountered in a dissertation [ Supplementary file 3A ].

Step 2. Does the data follow a normal distribution?[ 14 ]

Each study group as well as every parameter has to be checked for distribution analysis. This step will confirm whether the data of a particular group is normally distributed (parametric data) or does not follow the normal distribution (non-parametric data); subsequent statistical test selection mainly depends on the results of the distribution analysis. For example, one may choose the Student's’ test instead of the ‘Mann-Whitney U’ for non-parametric data, which may be incorrect. Each study group as well as every parameter has to be checked for distribution analysis [ Supplementary File 3B ].

Step 3. Calculation of measures of central tendency and measures of variability.

Measures of central tendency mainly include mean, median and mode whereas measures of variability include range, interquartile range (IQR), SD or variance not standard error of mean. Depending on Step 2 findings, one needs to make the appropriate choice. Mean and SD/variance are more often for normally distributed and median with IQR are the best measure for not normal (skewed) distribution. Proportions are used to describe the data whenever the sample size is ≥100. For a small sample size, especially when it is approximately 25-30, describe the data as 5/25 instead of 20%. Software used for statistical analysis automatically calculates the listed step 3 measures and thus makes the job easy.

Step 4. Which statistical test do I choose for necessary analysis?

Choosing a particular test [ Figure 3 ] is based on orderly placed questions which are addressed in the dissertation.[ 15 ]

Chosing a statistical test, (a). to find a difference between the groups of unpaired situations, (b). to find a difference between the groups of paired situations, (c). to find any association between the variables, (d). to find any agreement between the assessment techniques. ANOVA: Analysis of Variance. Reproduced with permission from Editor of Indian Journal of Ophthalmology, and the author, Dr Barun Nayak[ 15 ]

• Is there a difference between the groups of unpaired situations?
• Is there a difference between the groups of paired situations?
• Is there any association between the variables?
• Is there any agreement between the assessment techniques?

Perform necessary analysis using user-friendly software such as GraphPad Prism, Minitab or MedCalc,etc. Once the analysis is complete, appropriate writing in the text form is equally essential. Specific test names used to examine each part of the results have to be described. Simple listing of series of tests should not be done. A typical write-up can be seen in the subsequent sections of the supplementary files [Supplementary files 3C – E ]. One needs to state the level of significance and software details also.

Role of a statistician in dissertation and data analysis

Involving a statistician before planning a study design, prior to data collection, after data have been collected, and while data are analysed is desirable when conducting a dissertation. On the contrary, it is also true that self-learning of statistical analysis reduces the need for statisticians’ help and will improve the quality of research. A statistician is best compared to a mechanic of a car which we drive; he knows each element of the car, but it is we who have to drive it. Sometimes the statisticians may not be available for a student in an institute. Self-learning software tools, user-friendly statistical software for basic statistical analysis thus gain importance for students as well as guides. The statistician will design processes for data collection, gather numerical data, collect, analyse, and interpret data, identify the trends and relationships in data, perform statistical analysis and its interpretation, and finally assist in final conclusion writing.

Results are an important component of the dissertation and should follow clearly from the study objectives. Results (sometimes described as observations that are made by the researcher) should be presented after correct analysis of data, in an appropriate combination of text, charts, tables, graphs or diagrams. Decision has to be taken on each outcome; which outcome has to be presented in what format, at the beginning of writing itself. These should be statistically interpreted, but statistics should not surpass the dissertation results. The observations should always be described accurately and with factual or realistic values in results section, but should not be interpreted in the results section.

While writing, classification and reporting of the Results has to be done under five section paragraphs- population data, data distribution analysis, results of the primary outcome, results of secondary outcomes, any additional observations made such as a rare adverse event or a side effect (intended or unintended) or of any additional analysis that may have been done, such as subgroup analysis.

At each level, one may either encounter qualitative (n/N and %) or quantitative data (mean [SD], median [IQR] and so on.

In the first paragraph of Results while describing the population data, one has to write about included and excluded patients. One needs to cite the Consolidated Standards of Reporting Trials (CONSORT) flow chart to the text, at this stage. Subsequently, highlighting of age, sex, height, body mass index (BMI) and other study characteristics referring to the first table of ‘patients data’ should be considered. It is not desirable to detail all values and their comparison P values in the text again in population data as long as they are presented in a cited table. An example of this pattern can be seen in Supplementary file 3D .

In the second paragraph, one needs to explain how the data is distributed. It should be noted that, this is not a comparison between the study groups but represents data distribution for the individual study groups (Group A or Group B, separately)[ Supplementary file 3E ].

In the subsequent paragraph of Results , focused writing on results of the primary outcomes is very important. It should be attempted to mention most of the data outputs related to the primary outcomes as the study is concluded based on the results of this outcome analysis. The measures of central tendency and dispersion (Mean or median and SD or IQR etc., respectively), alongside the CIs, sample number and P values need to be mentioned. It should be noted that the CIs can be for the mean as well as for the mean difference and should not be interchanged. An example of this pattern can be seen in Supplementary file 3F .

A large number of the dissertations are guided for single primary outcome analysis, and also the results of multiple secondary outcomes are needed to be written. The primary outcome should be presented in detail, and secondary outcomes can be presented in tables or graphs only. This will help in avoiding a possible evaluator's fatigue. An example of this pattern can be seen in Supplementary file 3G .

In the last paragraph of the Results, mention any additional observations, such as a rare adverse event or side effect or describe the unexpected results. The results of any additional analysis (subgroup analysis) then need to be described too. An example of this pattern can be seen in Supplementary file 3H .

The most common error observed in the Results text is duplication of the data and analytical outputs. While using the text for summarising the results, at each level, it should not be forgotten to cite the table or graph but the information presented in a table should not be repeated in the text. Further, results should not be given to a greater degree of accuracy than that of the measurement. For example, mean (SD) age need to be presented as 34.5 (11.3) years instead of 34.5634 (11.349). The latter does not carry any additional information and is unnecessary. The actual P values need to be mentioned. The P value should not be simply stated as ‘ P < 0.05’; P value should be written with the actual numbers, such as ‘ P = 0.021’. The symbol ‘<’ should be used only when actual P value is <0.001 or <0.0001. One should try avoiding % calculations for a small sample especially when n < 100. The sample size calculation is a part of the methodology and should not be mentioned in the Results section.

The use of tables will help present actual data values especially when in large numbers. The data and their relationships can be easily understood by an appropriate table and one should avoid overwriting of results in the text format. All values of sample size, central tendency, dispersions, CIs and P value are to be presented in appropriate columns and rows. Preparing a dummy table for all outcomes on a rough paper before proceeding to Microsoft Excel may be contemplated. Appropriate title heading (e.g., Table 1 . Study Characteristics), Column Headings (e.g., Parameter studied, P values) should be presented. A footnote should be added whenever necessary. For outputs, where statistically significant P values are recorded, the same should be highlighted using an asterisk (*) symbol and the same *symbol should be cited in the footnote describing its value (e.g., * P < 0.001) which is self-explanatory for statistically significance. One should not use abbreviations such as ‘NS’ or ‘Sig’ for describing (non-) significance. Abbreviations should be described for all presented tables. A typical example of a table can be seen in Figure 4 .

Example of presenting a table

Graphical images

Similar to tables, the graphs and diagrams give a bird's-eye view of the entire data and therefore may easily be understood. bar diagrams (simple, multiple or component), pie charts, line diagrams, pictograms and spot maps suit qualitative data more whereas the histograms, frequency polygons, cumulative frequency, polygon scatter diagram, box and whisker plots and correlation diagrams are used to depict quantitative data. Too much presentation of graphs and images, selection of inappropriate or interchanging of graphs, unnecessary representation of three-dimensional graph for one-dimensional graphs, disproportionate sizes of length and width and incorrect scale and labelling of an axis should be avoided. All graphs should contain legends, abbreviation descriptions and a footnote. Appropriate labelling of the x - and the y -axis is also essential. Priori decided scale for axis data should be considered. The ‘error bar’ represents SDs or IQRs in the graphs and should be used irrespective of whether they are bar charts or line graphs. Not showing error bars in a graphical image is a gross mistake. An error bar can be shown on only one side of the line graph to keep it simple. A typical example of a graphical image can be seen in Figure 5 . The number of subjects (sample) is to be mentioned for each time point on the x -axis. An asterisk (*) needs to be put for data comparisons having statistically significant P value in the graph itself and they are self-explanatory with a ‘stand-alone’ graph.

Example of an incorrect (a) and correct (b) image

Once the results have been adequately analysed and described, the next step is to draw conclusions from the data and study. The main goal is to defend the work by staging a constructive debate with the literature.[ 16 ] Generally, the length of the ‘ Discussion ’ section should not exceed the sum of other sections (introduction, material and methods, and results).[ 17 ] Here the interpretation, importance/implications, relevance, limitations of the results are elaborated and should end in recommendations.

It is advisable to start by mentioning the RQ precisely, summarising the main findings without repeating the entire data or results again. The emphasis should be on how the results correlate with the RQ and the implications of these results, with the relevant review of literature (ROL). Do the results coincide with and add anything to the prevalent knowledge? If not, why not? It should justify the differences with plausible explanation. Ultimately it should be made clear, if the study has been successful in making some contribution to the existing evidence. The new results should not be introduced and any exaggerated deductions which cannot be corroborated by the outcomes should not be made.

The discussion should terminate with limitations of the study,[ 17 ] mentioned magnanimously. Indicating limitations of the study reflects objectivity of the authors. It should not enlist any errors, but should acknowledge the constraints and choices in designing, planning methodology or unanticipated challenges that may have cropped up during the actual conduct of the study. However, after listing the limitations, the validity of results pertaining to the RQ may be emphasised again.

This section should convey the precise and concise message as the take home message. The work carried out should be summarised and the answer found to the RQ should be succinctly highlighted. One should not start dwelling on the specific results but mention the overall gain or insights from the observations, especially, whether it fills the gap in the existing knowledge if any. The impact, it may have on the existing knowledge and practices needs to be reiterated.

What to do when we get a negative result?

Sometimes, despite the best research framework, the results obtained are inconclusive or may even challenge a few accepted assumptions.[ 18 ] These are frequently, but inappropriately, termed as negative results and the data as negative data. Students must believe that if the study design is robust and valid, if the confounders have been carefully neutralised and the outcome parameters measure what they are intended to, then no result is a negative result. In fact, such results force us to critically re-evaluate our current understanding of concepts and knowledge thereby helping in better decision making. Studies showing lack of prolongation of the apnoea desaturation safety periods at lower oxygen flows strengthened belief in the difficult airway guidelines which recommend nasal insufflations with at least 15 L/min oxygen.[ 19 , 20 , 21 ]

Publishing the dissertation work

There are many reporting guidelines based upon the design of research. These are a checklist, flow diagram, or structured text to guide authors in reporting a specific type of research, developed using explicit methodology. The CONSORT[ 22 ] and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiatives,[ 23 ] both included in the Enhancing the Quality and Transparency of Health Research (EQUATOR) international network, have elaborated appropriate suggestions to improve the transparency, clarity and completeness of scientific literature [ Figure 6 ].

Equator publishing tree

All authors are advised to follow the CONSORT/STROBE checklist attached as Supplementary file 4 , when writing and reporting their dissertation.

For most dissertations in Anaesthesiology, the CONSORT, STROBE, Standards for Reporting Diagnostic accuracy studies (STARD) or REporting recommendations for tumour MARKer prognostic studies (REMARK) guidelines would suffice.

Abstract and Summary

These two are the essential sections of a dissertation.

It should be at the beginning of the manuscript, after the title page and acknowledgments, but before the table of contents. The preparation varies as per the University guidelines, but generally ranges between 150 to 300 words. Although it comes at the very beginning of the thesis, it is the last part one writes. It must not be a ‘copy-paste job’ from the main manuscript, but well thought out miniaturisation, giving the overview of the entire text. As a rule, there should be no citation of references here.

Logically, it would have four components starting with aims, methods, results, and conclusion. One should begin the abstract with the research question/objectives precisely, avoiding excessive background information. Adjectives like, evaluate, investigate, test, compare raise the curiosity quotient of the reader. This is followed by a brief methodology highlighting only the core steps used. There is no need of mentioning the challenges, corrections, or modifications, if any. Finally, important results, which may be restricted to fulfilment (or not), of the primary objective should be mentioned. Abstracts end with the main conclusion stating whether a specific answer to the RQ was found/not found. Then recommendations as a policy statement or utility may be made taking care that it is implementable.

Keywords may be included in the abstract, as per the recommendations of the concerned university. The keywords are primarily useful as markers for future searches. Lastly, the random reader using any search engine may use these, and the identifiability is increased.

The summary most often, is either the last part of the Discussion or commonly, associated with the conclusions (Summary and Conclusions). Repetition of introduction, whole methodology, and all the results should be avoided. Summary, if individually written, should not be more than 150 to 300 words. It highlights the research question, methods used to investigate it, the outcomes/fallouts of these, and then the conclusion part may start.

References/bibliography

Writing References serves mainly two purposes. It is the tacit acknowledgement of the fact that someone else's written words or their ideas or their intellectual property (IP) are used, in part or in toto , to avoid any blame of plagiarism. It is to emphasise the circumspective and thorough literature search that has been carried out in preparation of the work.

Vancouver style for referencing is commonly used in biomedical dissertation writing. A reference list contains details of the works cited in the text of the document. (e.g. book, journal article, pamphlet, government reports, conference material, internet site). These details must include sufficient details so that others may locate and access those references.[ 24 ]

How much older the references can be cited, depends upon the university protocol. Conventionally accepted rule is anywhere between 5-10 years. About 85% of references should be dispersed in this time range. Remaining 15%, which may include older ones if they deal with theories, historical aspects, and any other factual content. Rather than citing an entire book, it is prudent to concentrate on the chapter or subsection of the text. There are subjective variations between universities on this matter. But, by and large, these are quoted as and when deemed necessary and with correct citation.

Bibliography is a separate list from the reference list and should be arranged alphabetically by writing name of the ‘author or title’ (where no author name is given) in the Vancouver style.

There are different aspects of writing the references.[ 24 ]

Citing the reference in the form of a number in the text. The work of other authors referred in the manuscript should be given a unique number and quoted. This is done in the order of their appearance in the text in chronological order by using Arabic numerals. The multiple publications of same author shall be written individually. If a reference article has more than six authors, all six names should be written, followed by “ et al .” to be used in lieu of other author names. It is desirable to write the names of the journals in abbreviations as per the NLM catalogue. Examples of writing references from the various sources may be found in the Supplementary file 5 .

Both the guide and the student have to work closely while searching the topic initially and also while finalising the submission of the dissertation. But the role of the guide in perusing the document in detail, and guiding the candidate through the required corrections by periodic updates and discussions cannot be over-emphasised.

Assessment of dissertations

Rarely, examiners might reject a dissertation for failure to choose a contemporary topic, a poor review of literature, defective methodology, biased analysis or incorrect conclusions. If these cannot be corrected satisfactorily, it will then be back to the drawing board for the researchers, who would have to start from scratch to redesign the study, keeping the deficiencies in mind this time.

Before submission, dissertation has to be run through “plagiarism detector” software, such as Turnitin or Grammarly to ensure that plagiarism does not happen even unwittingly. Informal guidelines state that the percentage plagiarism picked up by these tools should be <10%.

No work of art is devoid of mistakes/errors. Logically, a dissertation, being no exception, may also have errors. Our aim, is to minimise them.

The dissertation is an integral part in the professional journey of any medical post-graduate student. It is also an important responsibility for a guide to educate his protégé, the basics of research methodology through the process. Searching for a gap in literature and identification of a pertinent research question is the initial step. Careful planning of the study design is a vitally important aspect. After the conduct of study, writing the dissertation is an art for which the student often needs guidance. A good dissertation is a good description of a meticulously conducted study under the different headings described, utilising the various reporting guidelines. By avoiding some common errors as discussed in this manuscript, a good dissertation can result in a very fruitful addition to medical literature.
