How To Write The Conclusion Chapter

The What, Why & How Explained Simply (With Examples)

So, you’ve wrapped up your results and discussion chapters, and you’re finally on the home stretch – the conclusion chapter. In this post, we’ll discuss everything you need to know to craft a high-quality conclusion chapter for your dissertation or thesis project.

What exactly is the conclusion chapter?

The conclusion chapter is typically the final major chapter of a dissertation or thesis. As such, it serves as a concluding summary of your research findings and wraps up the document. While some publications such as journal articles and research reports combine the discussion and conclusion sections, these are typically separate chapters in a dissertation or thesis. As always, be sure to check what your university’s structural preference is before you start writing up these chapters.

So, what’s the difference between the discussion and the conclusion chapter?

Well, the two chapters are quite similar, as they both discuss the key findings of the study. However, the conclusion chapter is typically more general and high-level in nature. In your discussion chapter, you’ll typically discuss the intricate details of your study, but in your conclusion chapter, you’ll take a  broader perspective, reporting on the main research outcomes and how these addressed your research aim (or aims).

A core function of the conclusion chapter is to synthesise all major points covered in your study and to tell the reader what they should take away from your work. Basically, you need to tell them what you found, why it’s valuable, how it can be applied, and what further research can be done.

Whatever you do, don’t just copy and paste what you’ve written in your discussion chapter! The conclusion chapter should not be a simple rehash of the discussion chapter. While the two chapters are similar, they have distinctly different functions.

What should I include in the conclusion chapter?

To understand what needs to go into your conclusion chapter, it’s useful to understand what the chapter needs to achieve. In general, a good dissertation conclusion chapter should achieve the following:

  • Summarise the key findings of the study
  • Explicitly answer the research question(s) and address the research aims
  • Inform the reader of the study’s main contributions
  • Discuss any limitations or weaknesses of the study
  • Present recommendations for future research

Therefore, your conclusion chapter needs to cover these core components. Importantly, you need to be careful not to include any new findings or data points. Your conclusion chapter should be based purely on data and analysis findings that you’ve already presented in the earlier chapters. If there’s a new point you want to introduce, you’ll need to go back to your results and discussion chapters to weave the foundation in there.

In many cases, readers will jump from the introduction chapter directly to the conclusions chapter to get a quick overview of the study’s purpose and key findings. Therefore, when you write up your conclusion chapter, it’s useful to assume that the reader hasn’t consumed the inner chapters of your dissertation or thesis. In other words, craft your conclusion chapter such that there’s a strong connection and smooth flow between the introduction and conclusion chapters, even though they’re on opposite ends of your document.

How to write the conclusion chapter

Now that you have a clearer view of what the conclusion chapter is about, let’s break down the structure of this chapter so that you can get writing. Keep in mind that this is merely a typical structure – it’s not set in stone or universal. Some universities will prefer that you cover some of these points in the discussion chapter, or that you cover the points at different levels in different chapters.

Step 1: Craft a brief introduction section

As with all chapters in your dissertation or thesis, the conclusions chapter needs to start with a brief introduction. In this introductory section, you’ll want to tell the reader what they can expect to find in the chapter, and in what order. Here’s an example of what this might look like:

This chapter will conclude the study by summarising the key research findings in relation to the research aims and questions and discussing the value and contribution thereof. It will also review the limitations of the study and propose opportunities for future research.

Importantly, the objective here is just to give the reader a taste of what’s to come (a roadmap of sorts), not a summary of the chapter. So, keep it short and sweet – a paragraph or two should be ample.

Step 2: Discuss the overall findings in relation to the research aims

The next step in writing your conclusions chapter is to discuss the overall findings of your study, as they relate to the research aims and research questions. You would have likely covered similar ground in the discussion chapter, so it’s important to zoom out a little bit here and focus on the broader findings – specifically, how these help address the research aims.

In practical terms, it’s useful to start this section by reminding your reader of your research aims and research questions, so that the findings are well contextualised. In this section, phrases such as, “This study aimed to…” and “the results indicate that…” will likely come in handy. For example, you could say something like the following:

This study aimed to investigate the feeding habits of the naked mole-rat. The results indicate that naked mole rats feed on underground roots and tubers. Further findings show that these creatures eat only a part of the plant, leaving essential parts to ensure long-term food stability.

Be careful not to make overly bold claims here. Avoid claims such as “this study proves that” or “the findings disprove existing the existing theory”. It’s seldom the case that a single study can prove or disprove something. Typically, this is achieved by a broader body of research, not a single study – especially not a dissertation or thesis which will inherently have significant and limitations. We’ll discuss those limitations a little later.

Step 3: Discuss how your study contributes to the field Next, you’ll need to discuss how your research has contributed to the field – both in terms of theory and practice. This involves talking about what you achieved in your study, highlighting why this is important and valuable, and how it can be used or applied. In this section you’ll want to:
  • Mention any research outputs created as a result of your study (e.g., articles, publications, etc.)
  • Inform the reader on just how your research solves your research problem, and why that matters
  • Reflect on gaps in the existing research and discuss how your study contributes towards addressing these gaps
  • Discuss your study in relation to relevant theories. For example, does it confirm these theories or constructively challenge them?
  • Discuss how your research findings can be applied in the real world. For example, what specific actions can practitioners take, based on your findings?
Be careful to strike a careful balance between being firm but humble in your arguments here. It’s unlikely that your one study will fundamentally change paradigms or shake up the discipline, so making claims to this effect will be frowned upon. At the same time though, you need to present your arguments with confidence, firmly asserting the contribution your research has made, however small that contribution may be.

Step 4: Reflect on the limitations of your study Now that you’ve pumped your research up, the next step is to critically reflect on the limitations and potential shortcomings of your study. You may have already covered this in the discussion chapter, depending on your university’s structural preferences, so be careful not to repeat yourself unnecessarily. There are many potential limitations that can apply to any given study. Some common ones include:
  • Sampling issues that reduce the generalisability of the findings (e.g., non-probability sampling)
  • Insufficient sample size (e.g., not getting enough survey responses) or limited data access
  • Low-resolution data collection or analysis techniques
  • Researcher bias or lack of experience
  • Lack of access to research equipment
  • Time constraints that limit the methodology (e.g. cross-sectional vs longitudinal time horizon)
  • Budget constraints that limit various aspects of the study
Discussing the limitations of your research may feel self-defeating (no one wants to highlight their weaknesses, right), but it’s a critical component of high-quality research. It’s important to appreciate that all studies have limitations (even well-funded studies by expert researchers) – therefore acknowledging these limitations adds credibility to your research by showing that you understand the limitations of your research design. That being said, keep an eye on your wording and make sure that you don’t undermine your research. It’s important to strike a balance between recognising the limitations, but also highlighting the value of your research despite those limitations. Show the reader that you understand the limitations, that these were justified given your constraints, and that you know how they can be improved upon – this will get you marks.
You have to justify every choice in your dissertation defence
Step 5: Make recommendations for future research Next, you’ll need to make recommendations for future studies. This will largely be built on the limitations you just discussed. For example, if one of your study’s weaknesses was related to a specific data collection or analysis method, you can make a recommendation that future researchers undertake similar research using a more sophisticated method. Another potential source of future research recommendations is any data points or analysis findings that were interesting or surprising, but not directly related to your study’s research aims and research questions. So, if you observed anything that “stood out” in your analysis, but you didn’t explore it in your discussion (due to a lack of relevance to your research aims), you can earmark that for further exploration in this section. Essentially, this section is an opportunity to outline how other researchers can build on your study to take the research further and help develop the body of knowledge. So, think carefully about the new questions that your study has raised, and clearly outline these for future researchers to pick up on. Step 6: Wrap up with a closing summary Finally, it’s time to wrap up your conclusion chapter. The closing summary should serve as a quick reference for your readers, recapping what you discussed in the conclusion chapter. Brevity is key here – you only need to include the key takeaways and nothing more. Make sure that you don’t present any new information. In practical terms, this section should be a paragraph or two max.

Quick tips for a top-notch conclusion chapter

Now that we’ve covered the what, why and how of the conclusion chapter, here are some quick tips and suggestions to help you craft a rock-solid conclusion.

  • Don’t ramble. The conclusion chapter usually consumes 5-7% of the total word count (although this will vary between universities), so you need to be concise. Edit this chapter thoroughly with a focus on brevity and clarity.
  • Be very careful about the claims you make in terms of your study’s contribution. Nothing will make the marker’s eyes roll back faster than exaggerated or unfounded claims. Be humble but firm in your claim-making.
  • Use clear and simple language that can be easily understood by an intelligent layman. Remember that not every reader will be an expert in your field, so it’s important to make your writing accessible. Bear in mind that no one knows your research better than you do, so it’s important to spell things out clearly for readers.

Hopefully, this post has given you some direction and confidence to take on the conclusion chapter of your dissertation or thesis with confidence.
