How to write a discussion section?

Writing manuscripts to describe study outcomes, although not easy, is the main task of an academician. The aim of the present review is to outline the main aspects of writing the discussion section of a manuscript. Additionally, we address various issues regarding manuscripts in general. It is advisable to work on a manuscript regularly to avoid losing familiarity with the article. On principle, simple, clear and effective language should be used throughout the text. In addition, a pre-peer review process is recommended to obtain feedback on the manuscript. The discussion section can be written in 3 parts: an introductory paragraph, intermediate paragraphs and a conclusion paragraph. For intermediate paragraphs, a “divide and conquer” approach, meaning a full paragraph describing each of the study endpoints, can be used. In conclusion, academic writing is similar to other skills, and practice makes perfect.

Introduction

Sharing knowledge produced during academic life is achieved through writing manuscripts. However writing manuscripts is a challenging endeavour in that we physicians have a heavy workload, and English which is common language used for the dissemination of scientific knowledge is not our mother tongue.

The objective of this review is to summarize the method of writing ‘Discussion’ section which is the most important, but probably at the same time the most unlikable part of a manuscript, and demonstrate the easy ways we applied in our practice, and finally share the frequently made relevant mistakes. During this procedure, inevitably some issues which concerns general concept of manuscript writing process are dealt with. Therefore in this review we will deal with topics related to the general aspects of manuscript writing process, and specifically issues concerning only the ‘Discussion’ section.

A) Approaches to general aspects of manuscript writing process:

1. what should be the strategy of sparing time for manuscript writing be.

Two different approaches can be formulated on this issue? One of them is to allocate at least 30 minutes a day for writing a manuscript which amounts to 3.5 hours a week. This period of time is adequate for completion of a manuscript within a few weeks which can be generally considered as a long time interval. Fundamental advantage of this approach is to gain a habit of making academic researches if one complies with the designated time schedule, and to keep the manuscript writing motivation at persistently high levels. Another approach concerning this issue is to accomplish manuscript writing process within a week. With the latter approach, the target is rapidly attained. However longer time periods spent in order to concentrate on the subject matter can be boring, and lead to loss of motivation. Daily working requirements unrelated to the manuscript writing might intervene, and prolong manuscript writing process. Alienation periods can cause loss of time because of need for recurrent literature reviews. The most optimal approach to manuscript writing process is daily writing strategy where higher levels of motivation are persistently maintained.

Especially before writing the manuscript, the most important step at the start is to construct a draft, and completion of the manuscript on a theoretical basis. Therefore, during construction of a draft, attention distracting environment should be avoided, and this step should be completed within 1–2 hours. On the other hand, manuscript writing process should begin before the completion of the study (even the during project stage). The justification of this approach is to see the missing aspects of the study and the manuscript writing methodology, and try to solve the relevant problems before completion of the study. Generally, after completion of the study, it is very difficult to solve the problems which might be discerned during the writing process. Herein, at least drafts of the ‘Introduction’, and ‘Material and Methods’ can be written, and even tables containing numerical data can be constructed. These tables can be written down in the ‘Results’ section. [ 1 ]

2. How should the manuscript be written?

The most important principle to be remembered on this issue is to obey the criteria of simplicity, clarity, and effectiveness. [ 2 ] Herein, do not forget that, the objective should be to share our findings with the readers in an easily comprehensible format. Our approach on this subject is to write all structured parts of the manuscript at the same time, and start writing the manuscript while reading the first literature. Thus newly arisen connotations, and self-brain gyms will be promptly written down. However during this process your outcomes should be revealed fully, and roughly the message of the manuscript which be delivered. Thus with this so-called ‘hunter’s approach’ the target can be achieved directly, and rapidly. Another approach is ‘collectioner’s approach. [ 3 ] In this approach, firstly, potential data, and literature studies are gathered, read, and then selected ones are used. Since this approach suits with surgical point of view, probably ‘hunter’s approach’ serves our purposes more appropriately. However, in parallel with academic development, our novice colleague ‘manuscripters’ can prefer ‘collectioner’s approach.’

On the other hand, we think that research team consisting of different age groups has some advantages. Indeed young colleagues have the enthusiasm, and energy required for the conduction of the study, while middle-aged researchers have the knowledge to manage the research, and manuscript writing. Experienced researchers make guiding contributions to the manuscript. However working together in harmony requires assignment of a chief researcher, and periodically organizing advancement meetings. Besides, talents, skills, and experiences of the researchers in different fields (ie. research methods, contact with patients, preparation of a project, fund-raising, statistical analysis etc.) will determine task sharing, and make a favourable contribution to the perfection of the manuscript. Achievement of the shared duties within a predetermined time frame will sustain the motivation of the researchers, and prevent wearing out of updated data.

According to our point of view, ‘Abstract’ section of the manuscript should be written after completion of the manuscript. The reason for this is that during writing process of the main text, the significant study outcomes might become insignificant or vice versa. However, generally, before onset of the writing process of the manuscript, its abstract might be already presented in various congresses. During writing process, this abstract might be a useful guide which prevents deviation from the main objective of the manuscript.

On the other hand references should be promptly put in place while writing the manuscript, Sorting, and placement of the references should not be left to the last moment. Indeed, it might be very difficult to remember relevant references to be placed in the ‘Discussion’ section. For the placement of references use of software programs detailed in other sections is a rational approach.

3. Which target journal should be selected?

In essence, the methodology to be followed in writing the ‘Discussion’ section is directly related to the selection of the target journal. Indeed, in compliance with the writing rules of the target journal, limitations made on the number of words after onset of the writing process, effects mostly the ‘Discussion’ section. Proper matching of the manuscript with the appropriate journal requires clear, and complete comprehension of the available data from scientific point of view. Previously, similar articles might have been published, however innovative messages, and new perspectives on the relevant subject will facilitate acceptance of the article for publication. Nowadays, articles questioning available information, rather than confirmatory ones attract attention. However during this process, classical information should not be questioned except for special circumstances. For example manuscripts which lead to the conclusions as “laparoscopic surgery is more painful than open surgery” or “laparoscopic surgery can be performed without prior training” will not be accepted or they will be returned by the editor of the target journal to the authors with the request of critical review. Besides the target journal to be selected should be ready to accept articles with similar concept. In fact editors of the journal will not reserve the limited space in their journal for articles yielding similar conclusions.

The title of the manuscript is as important as the structured sections * of the manuscript. The title can be the most striking or the newest outcome among results obtained.

Before writing down the manuscript, determination of 2–3 titles increases the motivation of the authors towards the manuscript. During writing process of the manuscript one of these can be selected based on the intensity of the discussion. However the suitability of the title to the agenda of the target journal should be investigated beforehand. For example an article bearing the title “Use of barbed sutures in laparoscopic partial nephrectomy shortens warm ischemia time” should not be sent to “Original Investigations and Seminars in Urologic Oncology” Indeed the topic of the manuscript is out of the agenda of this journal.

4. Do we have to get a pre-peer review about the written manuscript?

Before submission of the manuscript to the target journal the opinions of internal, and external referees should be taken. [ 1 ] Internal referees can be considered in 2 categories as “General internal referees” and “expert internal referees” General internal referees (ie. our colleagues from other medical disciplines) are not directly concerned with your subject matter but as mentioned above they critically review the manuscript as for simplicity, clarity, and effectiveness of its writing style. Expert internal reviewers have a profound knowledge about the subject, and they can provide guidance about the writing process of the manuscript (ie. our senior colleagues more experienced than us). External referees are our colleagues who did not contribute to data collection of our study in any way, but we can request their opinions about the subject matter of the manuscript. Since they are unrelated both to the author(s), and subject matter of the manuscript, these referees can review our manuscript more objectively. Before sending the manuscript to internal, and external referees, we should contact with them, and ask them if they have time to review our manuscript. We should also give information about our subject matter. Otherwise pre-peer review process can delay publication of the manuscript, and decrease motivation of the authors. In conclusion, whoever the preferred referee will be, these internal, and external referees should respond the following questions objectively. 1) Does the manuscript contribute to the literature?; 2) Does it persuasive? 3) Is it suitable for the publication in the selected journal? 4) Has a simple, clear, and effective language been used throughout the manuscript? In line with the opinions of the referees, the manuscript can be critically reviewed, and perfected. [ 1 ]**

Following receival of the opinions of internal, and external referees, one should concentrate priorly on indicated problems, and their solutions. Comments coming from the reviewers should be criticized, but a defensive attitude should not be assumed during this evaluation process. During this “incubation” period where the comments of the internal, and external referees are awaited, literature should be reviewed once more. Indeed during this time interval a new article which you should consider in the ‘Discussion’ section can be cited in the literature.

5. What are the common mistakes made related to the writing process of a manuscript?

Probably the most important mistakes made related to the writing process of a manuscript include lack of a clear message of the manuscript , inclusion of more than one main idea in the same text or provision of numerous unrelated results at the same time so as to reinforce the assertions of the manuscript. This approach can be termed roughly as “loss of the focus of the study” In conclusion, the author(s) should ask themselves the following question at every stage of the writing process:. “What is the objective of the study? If you always get clear-cut answers whenever you ask this question, then the study is proceeding towards the right direction. Besides application of a template which contains the intended clear-cut messages to be followed will contribute to the communication of net messages.

One of the important mistakes is refraining from critical review of the manuscript as a whole after completion of the writing process. Therefore, the authors should go over the manuscript for at least three times after finalization of the manuscript based on joint decision. The first control should concentrate on the evaluation of the appropriateness of the logic of the manuscript, and its organization, and whether desired messages have been delivered or not. Secondly, syutax, and grammar of the manuscript should be controlled. It is appropriate to review the manuscript for the third time 1 or 2 weeks after completion of its writing process. Thus, evaluation of the “cooled” manuscript will be made from a more objective perspective, and assessment process of its integrity will be facilitated.

Other erroneous issues consist of superfluousness of the manuscript with unnecessary repetitions, undue, and recurrent references to the problems adressed in the manuscript or their solution methods, overcriticizing or overpraising other studies, and use of a pompous literary language overlooking the main objective of sharing information. [ 4 ]

B) Approaches to the writing process of the ‘Discussion’ section:

1. how should the main points of ‘discussion’ section be constructed.

Generally the length of the ‘Discussion ‘ section should not exceed the sum of other sections (ıntroduction, material and methods, and results), and it should be completed within 6–7 paragraphs.. Each paragraph should not contain more than 200 words, and hence words should be counted repeteadly. The ‘Discussion’ section can be generally divided into 3 separate paragraphs as. 1) Introductory paragraph, 2) Intermediate paragraphs, 3) Concluding paragraph.

The introductory paragraph contains the main idea of performing the study in question. Without repeating ‘Introduction’ section of the manuscript, the problem to be addressed, and its updateness are analysed. The introductory paragraph starts with an undebatable sentence, and proceeds with a part addressing the following questions as 1) On what issue we have to concentrate, discuss or elaborate? 2) What solutions can be recommended to solve this problem? 3) What will be the new, different, and innovative issue? 4) How will our study contribute to the solution of this problem An introductory paragraph in this format is helpful to accomodate reader to the rest of the Discussion section. However summarizing the basic findings of the experimental studies in the first paragraph is generally recommended by the editors of the journal. [ 5 ]

In the last paragraph of the Discussion section “strong points” of the study should be mentioned using “constrained”, and “not too strongly assertive” statements. Indicating limitations of the study will reflect objectivity of the authors, and provide answers to the questions which will be directed by the reviewers of the journal. On the other hand in the last paragraph, future directions or potential clinical applications may be emphasized.

2. How should the intermediate paragraphs of the Discussion section be formulated?

The reader passes through a test of boredom while reading paragraphs of the Discussion section apart from the introductory, and the last paragraphs. Herein your findings rather than those of the other researchers are discussed. The previous studies can be an explanation or reinforcement of your findings. Each paragraph should contain opinions in favour or against the topic discussed, critical evaluations, and learning points.

Our management approach for intermediate paragraphs is “divide and conquer” tactics. Accordingly, the findings of the study are determined in order of their importance, and a paragraph is constructed for each finding ( Figure 1 ). Each paragraph begins with an “indisputable” introductory sentence about the topic to be discussed. This sentence basically can be the answer to the question “What have we found?” Then a sentence associated with the subject matter to be discussed is written. Subsequently, in the light of the current literature this finding is discussed, new ideas on this subject are revealed, and the paragraph ends with a concluding remark.

Divide and Conquer tactics

In this paragraph, main topic should be emphasized without going into much detail. Its place, and importance among other studies should be indicated. However during this procedure studies should be presented in a logical sequence (ie. from past to present, from a few to many cases), and aspects of the study contradictory to other studies should be underlined. Results without any supportive evidence or equivocal results should not be written. Besides numerical values presented in the Results section should not be repeated unless required.

Besides, asking the following questions, and searching their answers in the same paragraph will facilitate writing process of the paragraph. [ 1 ] 1) Can the discussed result be false or inadequate? 2) Why is it false? (inadequate blinding, protocol contamination, lost to follow-up, lower statistical power of the study etc.), 3) What meaning does this outcome convey?

3. What are the common mistakes made in writing the Discussion section?:

Probably the most important mistake made while writing the Discussion section is the need for mentioning all literature references. One point to remember is that we are not writing a review article, and only the results related to this paragraph should be discussed. Meanwhile, each word of the paragraphs should be counted, and placed carefully. Each word whose removal will not change the meaning should be taken out from the text.” Writing a saga with “word salads” *** is one of the reasons for prompt rejection. Indeed, if the reviewer thinks that it is difficult to correct the Discussion section, he/she use her/ his vote in the direction of rejection to save time (Uniform requirements for manuscripts: International Comittee of Medical Journal Editors [ http://www.icmje.org/urm_full.pdf ])

The other important mistake is to give too much references, and irrelevancy between the references, and the section with these cited references. [ 3 ] While referring these studies, (excl. introductory sentences linking indisputable sentences or paragraphs) original articles should be cited. Abstracts should not be referred, and review articles should not be cited unless required very much.

4. What points should be paid attention about writing rules, and grammar?

As is the case with the whole article, text of the Discussion section should be written with a simple language, as if we are talking with our colleague. [ 2 ] Each sentence should indicate a single point, and it should not exceed 25–30 words. The priorly mentioned information which linked the previous sentence should be placed at the beginning of the sentence, while the new information should be located at the end of the sentence. During construction of the sentences, avoid unnecessary words, and active voice rather than passive voice should be used.**** Since conventionally passive voice is used in the scientific manuscripts written in the Turkish language, the above statement contradicts our writing habits. However, one should not refrain from beginning the sentences with the word “we”. Indeed, editors of the journal recommend use of active voice so as to increase the intelligibility of the manuscript.

In conclusion, the major point to remember is that the manuscript should be written complying with principles of simplicity, clarity, and effectiveness. In the light of these principles, as is the case in our daily practice, all components of the manuscript (IMRAD) can be written concurrently. In the ‘Discussion’ section ‘divide and conquer’ tactics remarkably facilitates writing process of the discussion. On the other hand, relevant or irrelevant feedbacks received from our colleagues can contribute to the perfection of the manuscript. Do not forget that none of the manuscripts is perfect, and one should not refrain from writing because of language problems, and related lack of experience.

Instead of structured sections of a manuscript (IMRAD): Introduction, Material and Methods, Results, and Discussion

Instead of in the Istanbul University Faculty of Medicine posters to be submitted in congresses are time to time discussed in Wednesday meetings, and opinions of the internal referees are obtained about the weak, and strong points of the study

Instead of a writing style which uses words or sentences with a weak logical meaning that do not lead the reader to any conclusion

Instead of “white color”; “proven”; nstead of “history”; “to”. should be used instead of “white in color”, “definitely proven”, “past history”, and “in order to”, respectively ( ref. 2 )

Instead of “No instances of either postoperative death or major complications occurred during the early post-operative period” use “There were no deaths or major complications occurred during the early post-operative period.

Instead of “Measurements were performed to evaluate the levels of CEA in the serum” use “We measured serum CEA levels”

The Final Chapter(s): Discussion, Conclusion, Limitations and Implications

Posted by Rene Tetzner | Oct 21, 2021 | PhD Success | 0 |

4.5 The Final Chapter(s): Discussion, Conclusion, Limitations and Implications

In some theses, the discussion of the study, its results and any concluding thoughts will fill more than one chapter: there may be, for instance, a chapter dedicated to discussion and a shorter conclusion chapter, or perhaps two chapters dedicated to discussing the results of different methodologies and a final chapter on relationships between those different results. In many theses, however, a single chapter will suffice for both. This final part of your thesis is a vital one: it tends to synthesise and analyse all elements of the thesis in order to evaluate and explain the overall significance of the research, and readers will often turn to the discussion (or conclusion) chapter first to obtain an overall picture of a study. The structure of this all-important final material varies considerably from thesis to thesis, yet it is essential that it be designed in a way that allows you to move through a great deal of potentially complicated, analytical and speculative information in an orderly fashion. Considerable reflection is therefore necessary before beginning to write, and not only to get the structure right. That structure depends, of course, on exactly what you intend to include in your discussion chapter(s), and deciding on exactly what to say will take some deep reflective thought on your part.

You may wish to address your plans for your discussion and conclusion chapter(s) with your supervisor and other committee members, and it is also a good idea to see if your department has any guidelines for this part of the thesis, especially if you are feeling unsure about how to proceed and could use some practical advice. In the final analysis, however, you are better acquainted with your research and thus better able to make sense of it than anyone else can be, so you are the only person truly qualified not only to write, but also to design the discussion and conclusion for that research. Besides, this final part of the thesis is your opportunity to express your own perspective and opinions on the significance of your doctoral research, based firmly, of course, on the topic, problem or phenomenon you investigated, your aims and objectives, the methods you used and the results you achieved.

Unfortunately, you may well feel rather exhausted by the experience of drafting your thesis by the time you arrive at your discussion chapter(s), but detailed analysis, intellectual vigour and creative connections are absolutely necessary for discussing and concluding your thesis, and a little passion never hurts either. Doing less than your best at this point would compromise all the effort you have already invested, so take a deep breath and dive into what can in fact be the most challenging and pleasurable part of writing a thesis. There is no simple or universal recipe for successfully discussing and concluding a doctoral thesis and its research, but, generally speaking, an inversion of your opening chapters takes place: in those chapters, you moved your reader from the more general background and scholarship associated with the topic, problem or phenomenon to focus on your particular perspective and approach; in your final chapter(s), you need to use the specific focus you adopted and the results you achieved to move your reader back out to the more general interpretations and implications of your research. In order to achieve this, there are a number of practical approaches and standard expectations that are worthy of serious consideration before forging your own unique path through the forest of possibilities.

Discussing and concluding a thesis effectively might and generally should involve:

• A brief introduction outlining the structure and content of the chapter(s). This can take the form of a single short paragraph, but because the discussion section of a thesis tends to be creative and is always unique, and it is essential that readers understand exactly what you intend, an opening paragraph of this sort can be extremely helpful for clarifying your approach and raising appropriate expectations.
• A brief but informative summary of the study or thesis as a whole. This need only highlight the major issues and can be done efficiently by moving through the individual chapters as outlined in the following four points.
• A return to the introduction of the thesis to restate the most important material introduced there. The research topic, problem or phenomenon should certainly be emphasised, as should its significance, your aims and objectives, and any research questions and hypotheses you introduced and used as guiding factors in your research. You will need to analyse how your research and results answer, resolve and contribute to knowledge in relation to these elements, so any or all of them can effectively be used to structure the chapter, especially if you have used them to organise your report of the results. You may also want to return to the essential aspects of the background and context of your research as discussed in the introduction chapter, but this tends to be necessary only if that background and context is immediately relevant to your discussion and concluding thoughts.
• A return to the literature review to highlight the most important aspects of previous research on your topic and any key theories related to your work in the thesis. Any gaps, misconceptions and limitations that you identified in the scholarship in your earlier literature review should be restated with the goal being to explain exactly how your research and its results have provided what was lacking, established new ways of looking at the problem(s) and thus moved beyond the traditional views and limitations. Your thesis should make an original contribution to knowledge and discussing it in relation to previous scholarship in the area is one of the most effective ways to identify, emphasise and explain that contribution.

• A return to the description of your methodology. This need not be long or detailed, but it sometimes is, and reviewing your main methods and approaches with an eye to evaluating their reliability, limitations and overall effectiveness is an important part of assessing your research. Your understanding of the appropriateness of your methodology may have changed since you first designed your study, particularly as you analysed and reported your results. Your methods may have exceeded or failed to live up to your expectations, or they may have presented limitations or complications you had not envisioned. You may have made errors while putting your methods into practice. Whatever the reality of your methodology proved to be should be explained accurately and objectively, so this is a place for complete if sometimes painful honesty.
• A return to the report of your results to summarise and highlight the key points. There is no need to go through your results in detail – the chapter(s) immediately preceding your discussion has already done that – but since you will need to use the results to discuss the implications and limitations of your research, mentioning the main trends is essential. You should focus particularly on the aspects of your results that you intend to discuss, but try not to leave out any significant or meaningful findings, including surprises, whether they support your research hypotheses or not. Focus and brevity can be achieved by making general statements about the nature of the results and following each statement with the most important examples and details to support it.
• An analysis and interpretation of your research as a whole and its results. This can be included in a step-by-step manner along with the summaries mentioned in the last four points above, or it can be tackled separately after the relevant information from previous chapters has been highlighted. Your approach, like your ideas, for this part of your thesis will require a great deal of reflection and you may find that you have to begin more than once before finding the right direction. The essential question is ‘What does it all mean?’ and the answer can be notoriously difficult to identify and explain both thoughtfully and accurately. It is likely that your research and results will have many meanings, but this is your chance to express your own views and opinions. These should not be whimsical, erratic, biassed or overly subjective, however, but should be solidly and logically based upon your findings. Your interpretations and conclusions should be plausible, insightful and comprehensive, and whenever your ideas are tentative or speculative (as they will necessarily be at times when discussing matters such as causality), your language should clearly indicate that with phrasing such as ‘it seems that,’ ‘these results appear to suggest,’ ‘it is probable that’ and ‘the likely explanation is.’ It is also important to explain how your research and results have resolved the problem you explored, answered your research questions, tested your hypotheses, filled gaps in the scholarship on the topic, revealed the limitations of earlier theories, proved the validity of your methodology and achieved your aims and objectives. If you have not met with success in any of these areas, that, too, should be indicated.

• An identification and analysis of the limitations of your study and its methodology. You may want to write this part along with the review of your main methods, but it can also work as a separate section of the chapter because limitations often extend beyond your methodology (to your findings, for instance). Identifying the limitations of your research and its results is a vital part of your thesis. You may prefer, of course, that there were no or very few limitations, but they are an inevitable aspect of any research, so recognising and discussing them not only demonstrates your intellectual maturity and critical skills, but also makes your research much more useful for future researchers in your area, including yourself. Limitations often stem from the nature of the research design and the exact qualities of the population or sample used, both of which might be called normal limitations that affect the generalisability of your research, but mistakes in controlling the relevant variables, defects in the instruments used or inadequate approaches to recording or analysing data will result in limitations (and perhaps unreliability) of a different kind. If any such limitations proved so significant that it was necessary to adjust your methods and/or repeat any of your research, a discussion of that process, the improvements you made and the ways in which the new results differed can be included as well, though you may want to consult your supervisor about this, as it might be more appropriate to discuss such changes in your methodology chapter(s) instead.
• A discussion of the implications of your research and its results. This will tie into your comments about the significance of your research project as expressed in your introduction to the thesis, but your understanding of that significance may well have changed since you began writing, and you can provide further details as well as more certain conclusions in this chapter based on the results you have presented. Implications, whether for practical action or intellectual reflection, should obviously be directly related to the topic, problem or phenomenon you explored (it can be helpful to imagine what you would tell an audience affected by the problem or phenomenon if you had only enough time to emphasise a few major points), and good use can be made of your research questions and hypotheses as well as your aims and objectives as you construct your discussion. The implications you identify should be considered in relation to the background and context of your research as well as previous scholarship in the area, including both trials and studies of a more theoretical nature – ask yourself how your results build on the literature you reviewed and how your study integrates with or overturns current theories. You may also want to comment on the implications of your methodology, especially if it has been innovative, problematic or extraordinarily successful. You will have a great deal of freedom in expressing your thoughts about your work – the factual reporter of your results chapter has been left behind for the authoritative thinker of your discussion – but be sure that the implications you identify and explain are based firmly and logically upon your research and its results, and when you are theorising, generalising and speculating, ensure that your language accurately reflects those tentative modes.
• One or more recommendations for future research in your area or discipline. Your recommendations for future research will be based to a large extent on the implications and limitations of your own research. It may be that some idealistic researchers start projects with the notion that their work will resolve all associated questions and problems, but this rarely (if ever) happens in reality, and often the answers that are derived from careful and extensive research complicate matters and open more doors on further research needs and possibilities. Your recommendations may involve repeating the kind of research you have done, but with changes that would eliminate the limitations you have identified (by adding controls, for instance, or choosing or developing different instruments, participants or means of analysis), or they may involve taking very different directions by conducting entirely different kinds of research (using entirely different methods perhaps, or focussing from a different perspective on the most unexpected or surprising trends of your results). Remember that your recommendations for future research can transform aspects of your work that may have proved disappointing into positive possibilities.
• A brief conclusion. Since conclusions about your study are a major part of this chapter, a conclusion to it may seem somewhat redundant, but it is important to end on a bright clear note. Sometimes an academic or scientific author will dedicate pages of text to describing, interpreting and speculating upon all the sound and revealing results he or she obtained only to turn at the end of the final chapter to the limitations of the study, which can have the effect of dumping all the wind out of the sails he or she has so carefully and convincingly filled. It may be that the guidelines provided by your university or department call for limitations to be reported at the end of the thesis, and, as an essential aspect of valuable research, limitations need not be negative, especially if they are combined with or (if possible) followed by recommendations for future research. However, after discussing the limitations of your study, it can be useful to return to the unquestionably positive results and conclusions of your research. You might choose, for instance, three main concepts or conclusions that you would like to highlight as you close your text, and these can certainly be qualified with hints of limitations and recommendations while still emphasising the significant contributions of your research. Keep in mind that a doctoral thesis should make a significant and original contribution to knowledge, so highlighting the main ways in which it does so in your final thoughts is not out of place. If there was ever a time to blow your own horn a little, this is it.

Why PhD Success?

To Graduate Successfully

This article is part of a book called "PhD Success" which focuses on the writing process of a phd thesis, with its aim being to provide sound practices and principles for reporting and formatting in text the methods, results and discussion of even the most innovative and unique research in ways that are clear, correct, professional and persuasive.

The assumption of the book is that the doctoral candidate reading it is both eager to write and more than capable of doing so, but nonetheless requires information and guidance on exactly what he or she should be writing and how best to approach the task. The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples.

The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples. PhD Success provides guidance for students familiar with English and the procedures of English universities, but it also acknowledges that many theses in the English language are now written by candidates whose first language is not English, so it carefully explains the scholarly styles, conventions and standards expected of a successful doctoral thesis in the English language.

Individual chapters of this book address reflective and critical writing early in the thesis process; working successfully with thesis supervisors and benefiting from commentary and criticism; drafting and revising effective thesis chapters and developing an academic or scientific argument; writing and formatting a thesis in clear and correct scholarly English; citing, quoting and documenting sources thoroughly and accurately; and preparing for and excelling in thesis meetings and examinations. 

Completing a doctoral thesis successfully requires long and penetrating thought, intellectual rigour and creativity, original research and sound methods (whether established or innovative), precision in recording detail and a wide-ranging thoroughness, as much perseverance and mental toughness as insight and brilliance, and, no matter how many helpful writing guides are consulted, a great deal of hard work over a significant period of time. Writing a thesis can be an enjoyable as well as a challenging experience, however, and even if it is not always so, the personal and professional rewards of achieving such an enormous goal are considerable, as all doctoral candidates no doubt realise, and will last a great deal longer than any problems that may be encountered during the process.

How to Write an Effective Thesis Discussion

Writing an effective thesis discussion can be challenging because it is so open ended. The purpose of the discussion is to (1) interpret your results, (2) discuss the significance of your results, (3) place your work in the context of previous work, (4) discuss the limitations of your study, and (5) suggest next steps to advance understanding and/or to improve real-world situations. The discussion section should expand upon ideas presented in the introduction, literature review, and results, and sometimes even the materials and methods. It should convince the reader that your work was worthwhile.

General considerations

Throughout a thesis or other scholarly manuscript, the results of completed studies should be described in the past tense (e.g. "36 of 43 patients showed improvement with treatment A, while only 25 of 44 patients showed improvement with treatment B"). In contrast, present tense is used to describe ideas that currently appear to be true based on available evidence (e.g. "treatment A is more effective than treatment B for most patients"). A good thesis discussion will typically progress from discussing specific results to discussing broader concepts that currently appear to be true.

You should include citations and modifying statements as needed (e.g. "Previous work by Lee et al. (2017) found no difference in the effectiveness of treatment A compared to treatment B. However , their study was limited to patients in advanced stages of the disease."). You will also need to include suggestions for further research, which can be described in present tense (e.g. "Additional studies are needed to determine. . .") or future tense (e.g. "Future studies will determine . . .").

I will now move into more detailed suggestions for each part of the discussion. Notice the occasional use of first-person pronouns (e.g. "I suggest. . ." or "We believe. . ."), which is now generally acceptable in many fields if used sparingly. Check the specific guidelines provided by your graduate program (and target journal). Also notice the use of subheadings to break the text into shorter sections on specific topics, which is recommended for any long manuscript.

Discussion part 1: Interpret your results

Your discussion should relate directly to the research question(s) you presented in the introduction, so a good way to start the discussion is to clearly restate your research question(s) (e.g. "The current study aimed to determine whether treatment A or treatment B was better for patients with condition X.") The discussion section follows the results section, so the next obvious step is to state what you can conclude from your results (e.g. "We found that a higher percentage of patients showed improvement with treatment A than with treatment B, and therefore conclude that treatment A is more effective than treatment B for most patients with condition X").

There are two general strategies for structuring the discussion of results. The first strategy is to discuss the results in the same order as they were presented in the results section. Alternatively, you can discuss your most interesting or surprising results first. This second strategy is most effective when the results are especially novel. As with any manuscript, the goal is to keep your reader engaged.

In some fields, the thesis discussion is expected to include comments on all of the results, even minor results that may not be statistically significant (e.g. "Treatments C, D, and E produced results that were statistically indistinguishable from placebo, leading to the conclusion that they were ineffective at the concentrations tested."). Note that you should not just state the results (e.g. "Treatments C, D, and E produced results that were statistically indistinguishable from placebo"), but should also state a conclusion (e.g. "they were ineffective at the concentrations tested").

In some other fields, brief comments on minor results are typically included in the results section, and the discussion section is used to elaborate on the most noteworthy results. In some cases, it may be appropriate to write a combined "results and discussion" section, where results are presented alongside initial conclusions, and broader implications are discussed toward the end. Check the requirements for your graduate program (and target journal).

Discussion part 2: Discuss the significance of your results

Clearly explain what is gained from your research. Sometimes a study is very significant (e.g. These results are among the first to show that treatment A is more effective than treatment B for condition X."). Other times—especially for undergraduate or master's theses based on a few months of data collection—the results primarily provide information about what doesn't work (e.g. "These results indicate that treatments C, D, and E are ineffective at physiologically relevant concentrations.)

Discuss some of the possibilities that your research opens up (e.g. "These results raise the possibility that early treatment could improve daily life for patients with mild cases of condition X, and might even delay disease progression.) but do not overstate (e.g. "These results prove that early treatment will improve daily life for patients with mild cases of condition X, and will delay disease progression."). Be optimistic but realistic, whether your results are highly significant or not (e.g. "These results suggest that the solubility of molecules like C, D, and E need to be improved before they can be effective.").

Discussing the significance of your results (part 2 of this essay) is a natural extension of discussing what your results mean (part 1 in this essay), and may not require a separate section.

Discussion part 3: Place your work in the context of previous work

Put your work into a broader context. Here you should revisit some of the previously published work that was described in your introduction and literature review, and clarify how your work expands upon or challenges that work. Most importantly, you should discuss how your work advances understanding in your research field.

For a thesis based on disappointing data, your ability to effectively discuss previous work and potential future work can support the argument that you have developed the necessary skills to move forward in research. These skills are further demonstrated by many other aspects of a well-researched and well-written thesis.

In some cases, your results may reveal unexpected connections. This may require you to discuss additional bodies of work in the discussion section, which can become a second literature review section. As you may be starting to see, there are many different topics you can include in your discussion section. You need to choose your topics carefully, and cover them in sufficient but not overwhelming detail. You want your discussion to cover all essential information, remain a manageable length, and retain the reader's interest. All of the different possibilities can make writing your discussion section very challenging.

If your results contradict previous work, you need to provide some possible explanations. As a rationale scholar, it is especially important to consider all reasonable options. It could be that (1) the earlier work was flawed, incomplete, or not exactly comparable to your work, or (2) your work is flawed, incomplete, or not exactly comparable to the earlier work. You might not be able to determine the exact cause of the discrepancy, but contradictions provide an obvious way to transition into the next section.

Discussion part 4: Discuss the limitations of your study

Every study has limitations, and here you should discuss the major limitations of your research. What can't the results tell us? In what situations are the findings not relevant or well supported? There may be limitations due to your sample population, experimental techniques, data analysis, etc. Discuss these limitations honestly, but then explain why your study is useful despite these limitations. You might point out that your study included multiple different populations, different experimental techniques, alternative methods of data analysis, etc. You might also emphasize that your conclusions are limited to a subset of a larger population, and that additional work needs to be done to determine whether the same conclusions apply to a larger population. This brings us to our next point.

Discussion part 5: Suggest next steps to advance understanding and/or to improve real-world situations

Once you've placed your work into a broader context, you can imagine the future possibilities. Here you might discuss questions that remain to be answered, or questions that have been newly raised by your work. There might be specific studies that would be an obvious extension of your work, and/or exploratory studies that would shed light on promising areas for novel research. Alternatively, you might suggest ways in which your research could be applied to real-world situations to improve outcomes.

Many manuscripts and presentations end with a discussion of possible next steps. I tend to like this type of ending for discussions of basic research, such as which genes are activated in which cells. However, other people recommend always ending with conclusions, where you restate the main findings of your research in a compact form. This might involve a separate "conclusions" section or as a final paragraph in the "discussion" section. Ending with conclusions makes a lot of sense for studies that might directly impact real-world situations (e.g. Treatment A it more effective than treatment B for condition X.).

In any event, you should follow departmental recommendations, and end with a compelling and memorable message for your readers.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

How to Write a Perfect Discussion Chapter for a PhD Thesis

Discussion chapter of a PhD thesis focuses on explaining and analyzing what you have researched, presenting how it is associated with the existing literature. It is also a place for argument supporting your entire discussion. We often find that people seek thesis writing help from experienced editing and proofreading services to prepare a flawless PhD discussion chapter. However, following 9 essential tips can help you design a perfect PhD thesis with an excellent discussion chapter.

This article provides 9 effective tips for writing a flawless discussion chapter for a PhD thesis. To give you an opportunity to practice proofreading, we have left a few spelling, punctuation, or grammatical errors in the text. See if you can spot them! If you spot the errors correctly, you will be entitled to a 10% discount.

Writing a flawless PhD thesis requires much more than only subject matter expertise. It requires expertise, experience, and in-depth thinking, along with sharp intelligence. Though most students add a discussion chapter in their thesis or dissertation, many of them end up messing up the essay or missing out the central issues.

A discussion chapter in a PhD thesis is a place where you have the chance to delving into the analysis, importance, and relevance of your research. This section focuses on explaining and analyzing what you have researched, presenting how it is associated with the existing literature. It is also a place for argument supporting your entire discussion. We often find that people seek thesis writing help from experienced editing and proofreading services to prepare a flawless PhD discussion chapter. However, the following 9 essential tips can help you design a perfect PhD thesis with an excellent discussion chapter.

1. Understand the objective of your PhD thesis

Before setting out to conduct a PhD thesis, researchers design and plan a study with objective(s) in mind. Such objectives inform how the dissertation is conducted. For example, no researcher would just commence by administering questionnaires or setting up laboratory equipment without an objective. It also informs the questions and necessary procedures to undertake. To write a well-conveyed discussion section in PhD thesis, the author must review and ascertain whether the conducted study addressed these objectives. It takes the understanding of the objective to assess the achievement of the objective clearly. Based on the assessment, the author finds the direction of his discussion. The comprehension of this objective is critical to crafting a focused discussion section in scholarly writing.

2. Determine a clear structure

The first step in organizing a perfect discussion chapter for a PhD thesis is to divide them into separate sections that move from a particular result to implications. However, depending on your PhD thesis topics, you may utilize the followings:

Analyze and summarize your main findings.

Evaluate how the results reflect the literature review.

Show if the discussion impacts the original hypothesis and, if yes, how it affects your hypothesis.

3. Usage of grammar and tense

The proper usage of grammar and tense is a key to a seamless PhD thesis. The improper use of grammar and tense can have the worst impact on the entire dissertation, along with the discussion chapter . Depending on the context, the usage of past and present tense should be made. When you are referring to specific data, the present tense can be used. For instance, when the light increases, speed decreases. However, while summarizing the result or concluding something, past tense can be used. For example, between 2013 and 2016, the number of car accidents decreased visibly. However, depending on the context, you can combine two tenses. Also, bear in mind that different manuals might require different tenses.

The tense adopted by the study should be uniform. Try to write the discussion chapter of your PhD thesis in the required tense format of your guideline. For instance, The  APA Publication Manual  provides suggestions on which verb tense is appropriate for various sections of a thesis:

Past tense or present perfect tense for the literature review and "the description of the procedure if the discussion is of past events."

"Use past tense to describe the "

"Use the present tense to discuss the implications of the results and to present the conclusions. By reporting conclusions in the present tense, you allow all readers to join you in deliberating the matter at hand."

As much as possible, try to be consistent with your chosen verb tense within a section as doing so "can help ensure smooth expression."

It is always best to check with your manual to get their opinion on the best approach for your thesis.

4. Referring to hypotheses and literature review

The primary purpose of referring to the literature review is to contextualize your discussion chapter as a part of the debate. For instance, suppose you introduce a theory claiming that speed cameras have zero effect on a road’s fatalities. You need to describe how your findings relate to this assumption. The same applies while making a hypothesis. Never forget this fact while discussing your results.

5. Evaluate your results and compare them with existing studies

While writing the discussion chapter of your PhD thesis, you need to analyze your results rather than just simplifying it. Don’t forget to do complete research on if your results agree or conflict with the previous studies.  You need to evaluate if there are any differences and, if yes, what the differences are. Comparing the development with existing studies helps your research to connect any existing debate. It also offers a solid base of conclusions.

In a well-written discussion chapter of a PhD thesis, an author should compare his/her findings with those of other studies reported in the literature. This aspect is different from a literature review in the sense that the author has data at hand to compare, as against the general overview made about a thesis’s objectives prior to the investigation. In comparing, the author is able to pronounce the authenticity of the results, especially when similar procedures were used in other studies. Any differences in findings can be explained using the different peculiarities between the author’s study and others. If this consideration is carefully made and implemented, the author may likely find evidence-based explanations for his/her findings. Even for novel findings, an author may still find relevant literature that formed the rudiments of the present study to discuss the progress, contribution, and novel dimension of the study. 

6. Why should the findings of your PhD thesis matter?  

After discussing the study results, the author, as part of his goal, must propose the impact of the study’s findings on the problem that informed the idea of the thesis. The reader will be better served if the author describes a roadmap for solving the problem based on the findings. Depending on the nature of the problem, an author may propose solutions to affect policy, behavioral change, or conventional practice. Only after making this contribution will a discussion section expose readers to the specific and general impacts of a PhD thesis.

7. Understand the limitation of your research

It is one of the most important things to evaluate when writing a discussion chapter for your PhD thesis. The discussion chapter of your research paper should involve some acknowledgment of the study limitations. Suppose you have critically assessed similar studies in the literature review; you are free to compare your work against their weakness or strength.

8. Don’t be afraid to be unique

The focus on research may change and evolve with time if you are working on a long-term project. The key to adjusting the focus on the literature review is to reflect these changes. Suppose you may find that specific themes are more prominent than others; it is helpful if you review your literature review and tweak them to emphasize the themes. Never be afraid to be unique to bring the changes.

Submitting a journal article can be a nerve-wracking experience. After all, this piece of work requires hours of research, analysis, and work poured into it. Therefore, you would wish for it to be acknowledged, selected, and published. This guide will give you some crucial answers, so go ahead and take a read. This way, you can ensure that your journal submission is devoid of any hassle.

There are various types of research designs that researchers can opt for. However, to opt for the right design, you first need to know the differences. Also, do not forget that the type of design depends on various variables from your research. Therefore, understanding these variables is of importance. If you are new to academic work or are just here to refresh your memory, this article has just the right content for you. Today, we will focus on the different types of research designs.

Academic writing is an intricate task. Add to this the troublesome misconception surrounding it and things seem much more unwelcoming than they already are. Almost every high-school student, college student, and/or research scholar has come across and maybe fallen for certain writing myths and burdened themselves with unneeded knowledge. In this article, we will look at 6 common myths that you should avoid in academic writing.

How Long Should the Discussion Section Be? Data from 61,517 Examples

I analyzed a random sample of 61,517 full-text research papers, uploaded to PubMed Central between the years 2016 and 2021, in order to answer the questions:

What is the typical length of a discussion section? and which factors influence it?

I used the BioC API to download the data (see the References section below).

Here’s a summary of the key findings

1. The median discussion section was 1,115 words long (equivalent to 43 sentences, or 7 paragraphs), and 90% of the discussion sections were between 482 and 2,230 words.

2. Compared to other sections in a research paper, the discussion was about the same length as either the methods or the results, and double the length of the introduction .

3. The length of the discussion does not differ between review articles and original research articles .

4. The quality of the journal does not influence the length of the discussion section .

Overall length of the discussion section

Here’s a table that describes the length of a discussion section in terms of words, sentences, and paragraphs:

From these data, we can conclude that the discussion sections in most research papers are between 824 and 1,480 words long (32 to 57 sentences).

If you are interested, here are the links to the articles with the shortest and longest discussion sections.

The discussion section constitutes 29.5% of the total word count in a research article, equivalent to the length of either the methods or the results, and double the length of the introduction [source: How Long Should a Research Paper Be? ].

Length of the discussion for different article types

The following table shows the median word count of the discussion section for different study designs:

The data show no clear pattern since the discussions of review articles and original research articles have almost similar word counts. So we can conclude that there is no particular article type that requires a longer discussion section.

Length of the discussion in different journals

In order to study the influence of the journal quality on the length of the discussion section, I ran a Poisson regression that models the discussion word count given the journal impact factor. Here’s the model output:

The model shows that a higher journal impact factor is associated with a slightly longer discussion section. Although statistically significant, this effect is practically negligible since a 1 unit increase in the journal impact factor is associated with an increase of only 0.1% in the discussion word count. For the median article, this means that a 1 unit increase in the journal impact factor is associated with an approximate increase of 1 word in the discussion section.

FAQ: Thesis Discussion Template

What types of dissertations/theses can this template be used for.

The discussion chapter template follows the standard format for academic research projects, which means it will be suitable for the majority of dissertations, theses and research projects (especially those within the sciences).

Keep in mind that the exact requirements for the discussion chapter/section will vary between universities and degree programs. For example, your university may require that the discussion chapter and conclusion chapter are merged into one, or that the results and discussion are covered together (this is often the case with qualitative research). So, be sure to double-check your university’s requirements before you finalise your structure.

Is this template for an undergrad, Master or PhD-level thesis?

This template can be used for a dissertation, thesis or research project at any level of study. Doctoral-level projects typically require the discussion chapter to be more extensive/comprehensive, but the structure will typically remain the same. Again, be sure to check your university’s requirements and norms in terms of document structure.

How long should the discussion chapter be?

This can vary a fair deal, depending on the level of study (undergrad, Master or Doctoral), the field of research, as well as your university’s specific requirements. Therefore, it’s best to check with your university or review past dissertations from your program to get an accurate estimate.

Can I share this template with my friends/colleagues?

Yes, you’re welcome to share this template in its original format (no editing allowed). If you want to post about it on your blog or social media, please reference this page as your source.

What format is the template (DOC, PDF, PPT, etc.)?

Thesis Outline Part 1 – Abstract, Contents, and Introduction

Thesis outline part 2 – methods, results, discussion, thesis outline part 3 – conclusions, recommendations, and references.

In academic writing, a thesis is related to complex papers. Usually, it is called a Master’s or a Doctoral thesis and can be compared to a dissertation. The main differences between them are size and width of uncovered topic. How long should a thesis be? 

Undeniably, it takes months to complete a well-researched work and it's easier to delegate this difficult task to professionals who will help write a thesis quickly and with quality in mind.

• Students place abstract on 2 pages
• An introduction should be placed on 3-5 pages
• The Methods section can be up to 10 pages long
• Results take 10 pages
• Discussion can be placed on 15 pages
• The conclusion takes 2-3 pages
• Appendix and other auxiliary parts of work can take up to 30 pages
• Complete paper contains 60-70 pages

If we take the article length, a dissertation should be at least three articles long. Read our guide to identify how long is a dissertation . Thesis takes space of one article. When university students choose a thesis to work on instead of a bibliographic essay, they do it for leaving a possibility to evaluate a research in the future.

There are more questions related to thesis writing appearing. What to include into a good text? If people make theses longer, will they become better? This article is a universal answer to all specific questions concerning proper writing.

Every academic paper begins with title page. Its structure depends on the chosen formatting style. An abstract follows it. This is an important part that describes thesis utility. It must be short and take 1-2 paragraphs, about 400 words and contain short summary of results, methods, etc. Here are questions to answer in this part:

• What was the reason to write this paper?
• What thesis statement to prove or disprove?
• What were your instruments? (describe main methods of research)
• What did you find out?
• Why are the results important?

Avoid citations, try to use more numbers. An abstract for dissertation or thesis should be qualitative. After it, the table of contents follows. Group all headings and subheadings into one complex list. If figures and tables are used, enlist their names, point page number of each one.

The first big part is the introduction for thesis . It may seem similar to an abstract. It pursues different goals – reader hooking, providing background information and logical transition to your own research. Here is what you need to disclose in this chapter:

• Enough background information about previous researches should be presented to make readers understand place of text in science system.
• Give an explanation concerning contents – what will be included into thesis.
• Provide readers with verbal ‘road maps’.
• Cite previous works. The citations must be related to text’s goals. Do not list everything you have read about subject.

These sections must take three pages of paper, excluding contents and table lists.

These are essential parts. They contain information concerning your own research. Answering main question of our post (how long should a thesis be?), these parts must take at least 30-40 pages. Let’s find out what Ph.D or Master’s thesis paper shoud present in these chapters.

The methods section is text’s explanatory part. There you have to provide readers with clear information and details that allow repeating the research and experiments. Traditionally, methods section is divided into three parts – materials, participants, ways of analysis. Materials imply full description of all instruments and quntitative and qualitative methods used for making research.

Participants part, just like a research paper discussion , describes people or subjects analyzed, including regulations of choice. Ways of analysis present all research approaches used to get results. This part describes area and circumstances of your experiments and helps to identify if they were legitimate and relevant.

Results part contains relevant statements of observations with statistical data, graphs, tables, etc. The section is divided into paragraphs, where key results are arranged into sentences at beginning. Do not forget about negative results, if possible. The main goal of section is data structuring to be helpful for readers to make own conclusions. Mention the nature of data found.

Discussion part is where you interpret results and adjust them to a thesis statement and goals. Disclose patterns and relationships between the observations found, find possible exceptions and discuss if the results correlate with previous researches. Each interpretation you make should be supplied with sufficient evidence. Define if materials are working for the future researches as well. This chapter is the richest in referencing to background material and other parts of your paper.

Here you make the strongest statement concerning observations. Highlight the information you want readers to remember. Explain how the results correlate with the problems you have indicated in the introduction. Describe all new things that are significant in finding a solution and provide limitations examples .

The recommendations part is for giving advice and indicating other actions that will help to solve particular problems. Sound your own opinion about the direction of future research. Most of the time you have to write it. Just like a research proposal . 

Acknowledgment for thesis  is a paragraph where you mention everyone who helped you with composition. Place all cited and used information resources into one list or form an annotated bibliography if needed.

All kinds of data used in writing, not cited and used resources directly go to the appendices part. This section is last. Along with conclusions they may take up to 10 pages.

What is the direct answer to our question? How long should a thesis be? Experts from a writing site assume, it takes about 60-70 pages. It depends on your research and subject. The length does not matter, actually. The most important thing you need to do is make a complete and complex paper. Provide everything from A to Z - no one will recall the thesis length.

Thesis Discussion Writing Guide For All Levels

A thesis discussion is the framing section of this paper. When writing this section, the author delves into the importance, meaning, and relevance of the results. The focus of this section should be on the explanation and evaluation of the findings. Here, you should show how your findings relate to the research questions and literature review. Your discussion should also make an argument that supports the overall conclusion.

The results and discussion in thesis form one of the most difficult parts to write. That’s because this section requires the author to think about the meaning and implication of their research. To be effective, the discussion chapter of a thesis should tell readers more about the meaning of the study and its importance. It should be well-written and organized to make it easier to read and understand.

Importance of Thesis Discussion

A discussion in thesis writing is a section that includes the interpretations and declaration of the writer’s opinions. It’s also the section where the writer explains the effects of their findings while making predictions and suggestions for future research. Here are some of the major reasons why the discussion section is important:

• It answers the questions posed in the thesis introduction
• It shows how the results of your research supported the answers to these questions
• It explains how those answers fit in the existing knowledge body about your research subject

A Ph.D. thesis discussion chapter can be maybe considered very important. Therefore, you might have to make several attempts when writing this chapter. Our thesis writers can help you out if you got stuck.

How to Write a Discussion Chapter in a Thesis

There are different ways of writing discussion for thesis. But, this chapter should start with the reiteration of the research problem and a summary of the major findings. All reported data should not be repeated in this section. However, the section should include a statement of the results that answers the research question. This introduction should not exceed a paragraph.

When writing a discussion, make sure that the introduction of your discussion chapter in thesis tells the readers what the results indicate or demonstrate. You can also tell your readers what the findings suggest or whether they support a certain theory. The discussion section of a thesis should essentially be focused on the following key elements.

• Identify patterns, correlations, and relationships of the data
• Discuss whether the findings supported the expectations you had or your hypothesis
• Contextualize the results within the existing theory or research
• Consider alternative explanations while arguing for your stance
• Explain the unexpected results and evaluate their significance
• Do your findings agree with the previous research and what addition do they have?
• Are your results different from those of previous studies and if so, why?
• Do the findings challenge or support the existing theories?
• What are the practical implications of your study?

The methodologies and research design that you use can cause limitations to your study. Unanticipated obstacles can also limit your study. Nevertheless, mention limitations only if they have direct relevance to the objectives of your research. Also, evaluate the impact of those limitations on the achievement of your research goals.

Good results and discussion thesis example can highlight a limited or small sample size as a limitation. This is a relevant limitation because it hinders the generalization of the findings.

Similarly, a discussion section can explain the problems encountered when analyzing or gathering data and how this influenced the findings. The effects of possible confounding variables that can’t be controlled should also be acknowledged in this section.

• Recommendations In some cases, the results and discussion sample thesis can feature recommendations for further research or practical implementation. However, there are cases where recommendations are featured in the conclusion.But, you can suggest further research immediately after stating the limitations of your study and their impact. Instead of just stating that further research is necessary, provide concrete ideas for future work. Show the readers how future studies can be built on the areas that your study couldn’t address.

What to Discuss in Discussion Thesis Chapter

Many learners want to know how to write discussion chapter in Ph.D. thesis because they don’t know what to discuss. Some learners are even confused between the discussion and conclusion chapters of a thesis. But, these chapters are different and they should have varying content.

Here’s what the discussion chapter should cover:

Interpretation of the research results Comparison of the results with those of the previous studies Contributions of your research to the existing knowledge body Limitations of the study Unexpected results How the results support or refute a certain theory or findings of the previous studies

On the other hand, a conclusion should mainly restate the hypothesis and the most important results. It should also highlight the limitations and significance of the study while suggesting a future direction.

How to Make Your Discussion More Effective? Avoid These Things!

Your discussion chapter should look like an inverted pyramid. Ideally, you should start from a general perspective and then narrow down to the specifics. But, make sure that your findings are linked to the literature, theory, and practice if possible. However, many learners don’t know how to do this. This is one of the major reasons why they want to learn how to write discussion thesis section.

For even better discussions, follow these tips to help with dissertation or thesis and to make it the best it can be:

• Restating your findings If you must remind your readers of the results of your study, use bridge sentences. For instance, tell your readers what a certain finding suggests instead of just re-stating it.
• Repeating recommendations Do not include recommendations in both the discussion and the conclusion parts of your paper. Instead, include recommendations either in the conclusion or discussion section of your thesis.
• Introducing new results Be careful to avoid introducing new results or information when trying to interpret a finding.
• Over-using first person This is one of the most important things to note when learning how to write a thesis discussion. You can use the first person in your thesis. However, using it excessively will distract your readers from your major points.

Learning how to write discussion section of thesis can make all the difference in terms of the grade that you graduate with from college or university. Stylistically, this section should read like bulleted points that have been written in paragraph form. Subheadings can be used if that makes sense. And, the length of this section should also depend on the scope of the study.

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

How to Write a Discussion Section | Tips & Examples

Published on 21 August 2022 by Shona McCombes . Revised on 25 October 2022.

The discussion section is where you delve into the meaning, importance, and relevance of your results .

It should focus on explaining and evaluating what you found, showing how it relates to your literature review , and making an argument in support of your overall conclusion . It should not be a second results section .

There are different ways to write this section, but you can focus your writing around these key elements:

• Summary: A brief recap of your key results
• Interpretations: What do your results mean?
• Implications: Why do your results matter?
• Limitations: What can’t your results tell us?
• Recommendations: Avenues for further studies or analyses

What not to include in your discussion section, step 1: summarise your key findings, step 2: give your interpretations, step 3: discuss the implications, step 4: acknowledge the limitations, step 5: share your recommendations, discussion section example.

There are a few common mistakes to avoid when writing the discussion section of your paper.

• Don’t introduce new results: You should only discuss the data that you have already reported in your results section .
• Don’t make inflated claims: Avoid overinterpretation and speculation that isn’t directly supported by your data.
• Don’t undermine your research: The discussion of limitations should aim to strengthen your credibility, not emphasise weaknesses or failures.

Correct my document today

Start this section by reiterating your research problem  and concisely summarising your major findings. Don’t just repeat all the data you have already reported – aim for a clear statement of the overall result that directly answers your main  research question . This should be no more than one paragraph.

Many students struggle with the differences between a discussion section and a results section . The crux of the matter is that your results sections should present your results, and your discussion section should subjectively evaluate them. Try not to blend elements of these two sections, in order to keep your paper sharp.

• The results indicate that …
• The study demonstrates a correlation between …
• This analysis supports the theory that …
• The data suggest  that …

The meaning of your results may seem obvious to you, but it’s important to spell out their significance for your reader, showing exactly how they answer your research question.

The form of your interpretations will depend on the type of research, but some typical approaches to interpreting the data include:

• Identifying correlations , patterns, and relationships among the data
• Discussing whether the results met your expectations or supported your hypotheses
• Contextualising your findings within previous research and theory
• Explaining unexpected results and evaluating their significance
• Considering possible alternative explanations and making an argument for your position

You can organise your discussion around key themes, hypotheses, or research questions, following the same structure as your results section. Alternatively, you can also begin by highlighting the most significant or unexpected results.

• In line with the hypothesis …
• Contrary to the hypothesised association …
• The results contradict the claims of Smith (2007) that …
• The results might suggest that x . However, based on the findings of similar studies, a more plausible explanation is x .

As well as giving your own interpretations, make sure to relate your results back to the scholarly work that you surveyed in the literature review . The discussion should show how your findings fit with existing knowledge, what new insights they contribute, and what consequences they have for theory or practice.

Ask yourself these questions:

• Do your results support or challenge existing theories? If they support existing theories, what new information do they contribute? If they challenge existing theories, why do you think that is?
• Are there any practical implications?

Your overall aim is to show the reader exactly what your research has contributed, and why they should care.

• These results build on existing evidence of …
• The results do not fit with the theory that …
• The experiment provides a new insight into the relationship between …
• These results should be taken into account when considering how to …
• The data contribute a clearer understanding of …
• While previous research has focused on  x , these results demonstrate that y .

Even the best research has its limitations. Acknowledging these is important to demonstrate your credibility. Limitations aren’t about listing your errors, but about providing an accurate picture of what can and cannot be concluded from your study.

Limitations might be due to your overall research design, specific methodological choices , or unanticipated obstacles that emerged during your research process.

Here are a few common possibilities:

• If your sample size was small or limited to a specific group of people, explain how generalisability is limited.
• If you encountered problems when gathering or analysing data, explain how these influenced the results.
• If there are potential confounding variables that you were unable to control, acknowledge the effect these may have had.

After noting the limitations, you can reiterate why the results are nonetheless valid for the purpose of answering your research question.

• The generalisability of the results is limited by …
• The reliability of these data is impacted by …
• Due to the lack of data on x , the results cannot confirm …
• The methodological choices were constrained by …
• It is beyond the scope of this study to …

Based on the discussion of your results, you can make recommendations for practical implementation or further research. Sometimes, the recommendations are saved for the conclusion .

Suggestions for further research can lead directly from the limitations. Don’t just state that more studies should be done – give concrete ideas for how future work can build on areas that your own research was unable to address.

• Further research is needed to establish …
• Future studies should take into account …
• Avenues for future research include …

How Long is a Dissertation for a PhD?

How long is a dissertation? This is one of the most common questions asked by current or aspiring doctoral students.

A dissertation is an extensive research project that contributes fresh knowledge to the author’s field. Many doctoral programs require students to write, defend, and revise a dissertation to earn their degrees.

Editorial Listing ShortCode:

This article explores the average length of a dissertation and various factors that affect the scope of these papers.

How Long Is a Dissertation?

For most graduate students, the dissertation is the longest and most time-consuming paper they write throughout their education. This project aims to address a research question in the student’s field and build on existing bodies of scholarship.

Additionally, the dissertation showcases the student’s mastery of research methodologies. Because a dissertation must accomplish several goals, they tend to be ambitious and lengthy.

Most dissertations are 100 to 250 pages long. But many factors impact the length of a dissertation, including:

• Academic field . Each discipline has different norms regarding dissertation content and length. For instance, literature dissertations often include extended close readings of texts, while science dissertations focus more on data analysis and research design. As a result, humanities dissertations are typically longer.
• Institutional requirements . Most colleges and universities specify a minimum number of pages for the dissertation. You can ask your academic advisor or the graduate studies office about specific dissertation guidelines.
• Topic complexity . Broad or complex research questions may require more data and analysis to answer, resulting in a longer dissertation.
• Individual writing style . Some doctoral students enjoy writing elaborate and detailed sentences, while others prefer to get straight to the point.
• Research methodologies . The approaches and methods used in the research can dramatically affect the length of the dissertation. For example, some dissertations include case studies, which may require lengthy explanations and analyses. Others use quantitative research methods and may include a number of charts and figures.
• Committee feedback . Graduate students typically write their dissertations under the supervision of a faculty committee. These professors may recommend adding or cutting material during revision, impacting the dissertation’s final length.
• Future goals . Some doctoral students plan to revise their dissertation and publish it as an academic monograph after graduation. Writing a longer dissertation gives them more material to adapt for their book.

Reading dissertations from your department and field can give you a better sense of the typical length.

How Long Are Dissertations by Discipline?

The answer to “how long is a doctoral dissertation?” varies by field. In some disciplines, it’s common for graduate students to spend several years writing extensive manuscripts. Other fields produce shorter dissertations of approximately 100 pages.

Here are a few examples of dissertation norms for different disciplines:

• Arts : Students studying art and creative writing may produce a creative dissertation. These projects typically consist of a theoretical introduction and a creative project, such as a poetry collection or a series of paintings. Creative dissertations may have fewer than 100 written pages, but the artistic elements can still be time-consuming.
• Chemistry : These dissertations typically range from 100 to 150 pages. They typically describe experimental methodologies and draw conclusions from the author’s findings.
• Computer science : Dissertations in this field are generally 50 to 150 pages long and often include quantitative data and algorithms.
• English : PhD students in this field frequently write lengthy literature reviews and provide in-depth analyses of novels and other texts. English dissertations may range from 200 to 350 pages.

Faculty in your discipline can help you understand dissertation expectations.

Average Dissertation Length Per Chapter

Dissertations typically have similar components and structures across disciplines. Here are six common chapters and their average lengths:

• Introduction : The first chapter introduces the primary research topic and explains its relevance to the field. The introduction also provides a brief overview of the investigation method. Most introductions are 10 to 25 pages long.
• Literature review : This chapter situates the project within the broader discipline. The author analyzes existing sources already written on their research topic and identifies biases or gaps that their own project remedies. Humanities dissertations tend to have 20 to 30 page literature reviews, while STEM dissertations devote 10 to 20 pages to this component.
• Methodology : The third chapter typically focuses on the methods and techniques used to gather data. Ideally, this description should contain all the details that another researcher would need to duplicate the experiment and verify the results. The methodology chapter ranges from 15 to 25 pages, depending on the complexity of the research.
• Findings : This section analyzes the collected data and discusses the results of the research project. It often includes charts, diagrams, and other data visualizations illustrating the findings. This chapter could be 20 to 50 pages, depending on the number of images and the amount of text needed to thoroughly examine the results.
• Discussion : This chapter explains the significance of the results. The author may also compare their findings to previously published scholarship. The discussion is typically 15 to 25 pages.
• Conclusion : The author summarizes their findings, acknowledges the limitations of their research, and suggests avenues for future studies. Most conclusions consist of 15 to 20 pages.

Some dissertations deviate from this format. For instance, English dissertations may devote several chapters to critical analyses of different genres or authors.

What Is a Dissertation?

A dissertation is a lengthy written document that a doctoral student produces based on their original research. This project demonstrates the student’s expertise in their area of specialty and contributes to existing knowledge in the field.

Dissertations typically fall into one of two categories. Empirical dissertations require students to collect and analyze data. For instance, a psychology student may interview people about their mental health, while a marketing student could interpret sales data.

Theoretical dissertations focus on analyzing existing scholarship and secondary sources. For example, a literature student might research psychoanalysis and apply this approach to superhero comics.

How Many Pages Is a Dissertation?

The length of a dissertation varies by discipline, institution, and research project. Some dissertations can be as short as 50 pages, while others may total 400 pages. But the average dissertation ranges from 100 pages to 250 pages.

Dissertations in the humanities and social sciences are typically the most extensive. These projects often include detailed analyses, case studies, and literature reviews. By contrast, dissertations in STEM fields like economics and mathematics are often 150 pages or less.

Students in these disciplines frequently use mathematical formulas and data visualizations to prove their findings, resulting in less text.

Why Are Dissertations So Long?

Dissertations are typically the most extended assignments that students complete in graduate school. Several factors contribute to their length, including:

• Depth of research . Doctoral students can spend several years researching their topic and analyzing data. This extensive work often takes hundreds of pages to summarize and explain.
• Literature review . Most fields have extensive bodies of scholarship, so students spend many pages analyzing sources and contextualizing their projects.
• Bibliography . Dissertations often cite dozens or even hundreds of sources, resulting in lengthy bibliographies.

Also, colleges often require dissertations to include additional materials like abstracts and tables of content.

What’s the Difference Between a Dissertation vs. Thesis?

Depending on the type of graduate program you enroll in, you may be required to write a dissertation or thesis. Here are the main differences between a thesis vs. dissertation .

If you want to develop your own concepts or theories, a dissertation can help you accomplish this goal.

What’s the Difference Between a Capstone vs. Dissertation?

There are doctorate programs with no dissertation. Like some online doctoral programs in education without dissertation requirements, they have a capstone project instead. Here’s a comparison of a dissertation vs. capstone .

Your career goals can help determine if a capstone or dissertation is right for you.

How Long Is a Dissertation for a PhD Degree?

People often wonder, “How long is a PhD dissertation?” These projects are typically 100 to 250 pages long, though dissertations on complex topics may total more than 400 pages.

Writing a dissertation allows you to develop advanced expertise on your chosen research topic.

How Long is a Thesis or Dissertation: College, Grad or PhD

How long is a thesis

As a graduate student, you may have heard that you must complete a certain comprehensive project, either a thesis or a dissertation. In this guide, we will explore how long a thesis should be, the best length for a dissertation, and the optimal length for each part of the two.

If you read on to the end, we will also explore their differences to understand how it informs each length.

Both terms have distinct meanings, although they are sometimes used interchangeably and frequently confused.

Structure-wise, both papers have an introduction, a literature review, a body, a conclusion, a bibliography, and an appendix. That aside, both papers have some differences, as we shall see later on in this article.

How Long Should a Thesis be

Before discussing how long a thesis is, it’s critical to understand what it is. A thesis is a paper that marks the end of a study program.

Mostly, there is the undergraduate thesis, a project that marks the end of a bachelor’s degree, and a master’s thesis that marks the end of a master’s program.

A thesis should be around 50 pages long for a bachelor’s degree and 60-100 pages for a Master’s degree. However, the optimal length of a thesis project depends on the faculty’s instructions and the supervising professor’s expectations . The length also depends on the topic’s technicalities and the extent of research done.

A master’s thesis project is longer because it is a compilation of all your knowledge obtained in your master’s degree.

It basically allows you to demonstrate your abilities in your chosen field.

Often, graduate schools require students pursuing research-oriented degrees to write a thesis.

This is to demonstrate their practical skills before completing their degrees.

In contrast to undergraduate thesis, which are shorter in length and coverage area, usually less than 60 pages. A master’s theses are lengthy scholarly work allowing you to research a topic deeply.

Then you are required to write, expand the topic, and demonstrate what you have learned throughout the program. This is part of why you must write a thesis for some undergrad in some of the courses.

A Master’s thesis necessitates a large amount of research, which may include conducting interviews, surveys, and gathering information ( both primary and secondary) depending on the subject and field of study.

For this reason, the master’s thesis has between 60 and 100 pages, without including the bibliography. Mostly, the topic and research approach determine the length of the paper.

This means that there is no definite number of pages required. However, your thesis should be long enough to clearly and concisely present all important information.

Need Help with your Homework or Essays?

How long should a dissertation be.

A dissertation is a complex, in-depth research paper usually written by Ph.D. students. When writing the dissertation, Ph.D. Students are required to create their research, formulate a hypothesis, and conduct the study.

On average, a dissertation should be at least 90 pages at the minimum and 200 pages at the maximum , depending on the guidelines of the faculty and the professor. The optimal length for a dissertation also depends on the depth of the research done, the components of the file, and the level of study.

Most Ph.D. dissertations papers are between 120 to 200 pages on average.

However, as we said earlier, it all depends on factors like the field of study, and methods of data collection, among others.

Unlike a master’s thesis, which is about 100 pages, a dissertation is at least twice this length.

This is because you must develop a completely new concept, study it, research it, and defend it.

In your Ph.D. program, a dissertation allows you the opportunity to bring new knowledge, theories, or practices to your field of study.

The Lengths of Each Part of a Thesis and Dissertation

Factors determining the length of thesis or dissertation.

As we have seen, there is no definite length of a thesis and dissertation. Most of these two important academic documents average 100 to 400 pages. However, several factors determine their length.

Universities- we all know universities are independent bodies. Also, it’s important to know that each university is different from the other. As a result, the thesis and dissertation length varies depending on the set rules in a certain college or school.

Field of study- some fields of study have rich information, while others have limited information.

For example, you may have much to write about or discover when it comes to science compared to history.

As such, if you are to write a thesis or a dissertation in both fields, one will definitely be longer than the other. Check the time it takes to write a thesis or a dissertation to get more points.

Other factors that affect the length of a thesis or a dissertation include your writing style and the instructor’s specifications. These factors also come into play when it comes to the time taken to defend a thesis or your dissertation.

Tips for the Optimal Length for a Thesis or Dissertation

Instead of writing for length, write for brevity. The goal is to write the smallest feasible document with all of the material needed to describe the study and back up the interpretation. Ensure to avoid irrelevant tangents and excessive repetitions at all costs.

The only repetition required is the main theme. The working hypothesis seeks to be elaborated and proved in your paper.

The theme is developed in the introduction, expanded in the body, and mentioned in the abstract and conclusion.

Here are some tips for writing the right length of thesis and dissertation:

• Remove any interpretation portion which is only tangentially linked to your new findings. 
• Use tables to keep track of information that is repeated.
• Include enough background information for the reader to understand the point of view.
• Make good use of figure captions.
• Let the table stand on its own. I.e., do not describe the contents of the figures and/or tables one by one in the text. Instead, highlight the most important patterns, objects, or trends in the figures and tables in the text.
• Leave out any observations or results in the text that you haven’t provided data.
• Do not include conclusions that aren’t backed up by your findings.
• Remove all inconclusive interpretation and discussion portions. 
• Avoid unnecessary adjectives, prepositional phrases, and adverbs.
• Make your sentences shorter – avoid nesting clauses or phrases.
• Avoid idioms and instead use words whose meaning can be looked up in a dictionary.

Difference between a Thesis and a Dissertation

The most basic distinction between a thesis and a dissertation is when they are written.

While a thesis is a project completed after a master’s program, a dissertation is completed at the end of doctorate studies.

In a thesis, you present the results of your research to demonstrate that you have a thorough understanding of what you have studied during your master’s program.

On the other hand,  a dissertation is your chance to add new knowledge, theories, or practices to your field while pursuing a doctorate. The goal here is to come up with a completely new concept, develop it, and defend it.

A master’s thesis is similar to the types of research papers you’re used to writing in your bachelor’s studies. It involves conducting research on a topic, analyzing it, and then commenting on your findings and how it applies to your research topic.

The thesis aims to demonstrate your capacity to think critically about and explain a topic in depth.

Furthermore, with a thesis, you typically use this time to elaborate on a topic that is most relevant to your professional area of specialization that you intend to pursue.

In a dissertation, on the other hand, you use other people’s research as an inspiration to help you come up with and prove your own hypothesis, idea, or concept. The majority of the data in a dissertation is credited to you.

Last but not least, these two major works differ greatly in length. The average length of a master’s thesis is at least 100 pages.

On the other hand, a doctoral dissertation should be substantially longer because it includes a lot of history and research information, as well as every element of your research, while explaining how you arrived at the information.

It is a complex piece of scholarly work, and it is likely to be twice or thrice the length of a thesis. To know the difference, check the best length for a thesis paper and see more about it.

Here is a Recap of the Differences

• While the thesis is completed at the end of your master’s degree program, a dissertation is written at the end of your doctoral degree program.
• Both documents also vary in length. A thesis should have at least 100 pages, while a doctoral dissertation is longer (over 200 pages)
• In the thesis, you conduct original research; in the dissertation, you use existing research to help you develop your discovery.
• For a thesis, you have to add analysis to the existing work, while a dissertation is part of the analysis of the existing work.
• In comparison to a thesis, a dissertation requires a more thorough study to expand your research in a certain topic.
• The statements in a thesis and a dissertation are distinct. While a thesis statement explains to readers how you will prove an argument in your research, a dissertation hypothesis defines and clarifies the outcomes you expect from your study. Here, you apply a theory to explore a certain topic.
• A dissertation allows you to contribute new knowledge to your field of study, while a thesis makes sure you understand what you have studied in your program and how it applies.

A thesis or a dissertation is a difficult document to compile. However, you should not be worried since your school assigns you a dissertation advisor who is a faculty member.

These advisors or supervisors help you find resources and ensure that your proposal is on the right track when you get stuck.

The length of introductions vary depending on your disciplinary area and the nature of your project so before writing one, it may be wise to discuss length and expectations of content with your supervisor. It is also worth taking a look at a range of past theses in your area to see what is expected in your field.

The introduction to the whole thesis can make up roughly 10 per cent of the total word count. So if you are doing a PhD of 80,000 - 100,000 words, you may have a 8,000 - 10,000 word introduction. And if you are writing a Masters thesis of 15,000 - 20,000 words, your introduction could be 1,500 - 2,000 words long. Exegeses tend to be anywhere between seven to 12 pages in length (1.5 cm spacing) and include images and/or diagrams.

Theses that generally have longer introductions do so because they incorporate more substantial background information and/or an extended literature review section.

Theses that have shorter introductions, say eight to ten pages (1.5 spacing) or about 4000 words for a PhD, do so in order to give a broad overview of the research project which is typically followed by a longer background or literature review chapter. 

Regardless of the type of project you are doing or thesis you are writing, the introduction to the thesis or exegesis should give a broad overview of the project, as discussed in the page on introductions. 

Individual chapters should also have introductions. An introduction to a chapter that is 10,000 words long could be about two to three pages long, whereas in shorter theses the chapter introductions may only be a page or two, or even just a paragraph or two. The length varies depending on how much you need to establish for your reader to understand how the chapter contributes to your research and argument.
