The discussion chapter is where you show your marker that you understand what your findings mean. It is usually where the highest marks are won or lost. A strong discussion does more than repeat results: it interprets them, links them to the literature and is honest about their limits. This guide shows you how.
Short answer: for each research question, restate the key finding briefly, explain what it means, compare it with the existing literature, and state what follows from it. Then cover implications and limitations, and add no new results.

What the Discussion Chapter Does
The discussion chapter answers the question "so what?". Your results chapter reports what you found. Your discussion explains what it means, why it may have happened, how it fits with previous research and what it implies. It is often around 20–25% of the total word count, so roughly 2,000–2,500 words in a 10,000-word dissertation, although your department's guidance always takes priority.

Results vs Discussion vs Conclusion
| Results | Discussion | Conclusion | |
|---|---|---|---|
| Main job | Report what you found | Explain what it means | Answer the research question |
| Literature | Rarely used | Central: compare your findings with it | Used only where needed |
| Interpretation | None | Detailed | Brief and overall |
| New material | Presents your data | None | None |
See our guides to writing the results chapter and writing the conclusion for the chapters on either side.
How to Structure It
1. Open with a short introduction
Remind the reader of your aim and research questions, and outline how the chapter is organised.
2. Discuss one research question or theme at a time
Use the same order as your introduction and results. Each section interprets the relevant findings and links them to the literature.
3. Explain unexpected results
If a finding surprised you, say so and offer reasoned explanations rather than ignoring it.
4. State the implications
Say what your findings mean for theory, practice or policy, depending on your field.
5. Acknowledge limitations
Explain the main limits of your study and how they affect how far the findings can be trusted or generalised.
6. End with a short summary
Pull the main points together in a few sentences, then hand over to the conclusion.
How to Interpret a Finding
A simple pattern works for each key finding:
- State it in one sentence, without repeating the full table.
- Explain it: what does it mean, and why might it have occurred?
- Compare it with the literature: does it agree, extend or contradict earlier studies?
- Say what follows: what does it imply for your research question?
Before interpreting a statistical result, be sure you know what the test does and does not show. Our guide on which statistical test to use explains how tests are matched to questions, and how to interpret regression output in SPSS covers reading regression results correctly.
Weaker vs Better Example
This fictional example continues the study on flexible working used in our dissertation introduction guide. Use it as a model for structure, not as text to copy.
Weaker: "Participants said they liked flexible working. Many said it helped them. This agrees with the literature."
Better: "Participants linked flexible working to better wellbeing mainly when they controlled their own schedules. This supports earlier research in large organisations that identifies autonomy as a key factor [citation], but extends it: in these small firms, flexibility also depended on colleagues' availability, which suggests that team size shapes how flexibility is experienced. This matters for owner-managers, who may need to agree core hours rather than allow complete freedom."
The better version states the finding, explains it, connects it to the literature and says what follows from it.
Limitations and Implications
Limitations: be specific and constructive, for example a small or single-region sample, reliance on self-reported data, or a design that cannot show causation. Explain what each limitation means for how the findings should be read, not just that it exists.
Implications: say who might use your findings, such as practitioners, policymakers or other researchers, and what they might do differently. Keep them grounded in your evidence. This links to your methodology, where you justified your design choices.
Common Mistakes
⚠️ Repeating the results. The most common error. If your discussion mostly restates numbers or quotes, you are not yet interpreting them.
- Introducing new results that were not in your results chapter
- Ignoring the literature or not comparing findings with earlier studies
- Overclaiming, such as saying a finding "proves" something your design cannot show
- Hiding unexpected or non-significant findings
- Skipping limitations or listing them without explaining their effect
