Discussion

What should I include in the discussion section?

The purpose of the discussion section is to interpret your findings and discuss these against the context of the wider literature. This section should also highlight how your research has contributed to the understanding of a phenomenon or problem: this can be achieved by responding to your research questions.

Although the structure of discussion sections can vary, a relatively common structure is offered below:

• State your major findings – this can be a brief opening paragraph that restates the research problem, the methods you used to attempt to address this, and the major findings of your research.
• Address your research questions - detail your findings in relation to each of your research questions to help demonstrate how you have attempted to address the research problem. Answer each research question in turn by interpreting the relevant results: this may involve highlighting patterns, relationships or statistically significant differences depending on the design of your research and how you analysed your data.
• Discuss your findings against the wider literature - this will involve comparing and contrasting your findings against those of others and using key literature to support the interpretation of your results; often, this will involve revisiting key studies from your literature review and discussing where your findings fit in the pre-existing literature. This process can help to highlight the importance of your research through demonstrating what is novel about your findings and how this contributes to the wider understanding of your research area.
• Address any unexpected findings in your study - begin with by stating the unexpected finding and then offer your interpretation as to why this might have occurred. You may relate unexpected findings to other research literature and you should also consider how any unexpected findings relate to your overall study – especially if you think this is significant in terms of what your findings contribute to the understanding of your research problem!
• Discuss alternative interpretations - it’s important to remember that in research we find evidence to support ideas, theories and understanding; nothing is ever proven. Consequently, you should discuss possible alternative interpretations of your data – not just those that neatly answer your research questions and confirm your hypotheses.
• Limitations/weaknesses of your research – acknowledge any factors that might have affected your findings and discuss how this relates to your interpretation of the data. This might include detailing problems with your data collection method, or unanticipated factors that you had not accounted for in your original research plan. Likewise, detail any questions that your findings could not answer and explain why this was the case.
• Future directions (this part of your discussion could also be included in your conclusion) – this section should address what questions remain unanswered about your research problem. For example, it may be that your findings have answered some questions but raised new ones; this can often occur as a result of unanticipated findings. Likewise, some of the limitations of your research may necessitate further work to address a methodological confound or weakness in a tool of measurement. Whatever these future directions are, remember you’re not writing a proposal for this further research; a brief suggestion of what the research should do and how this would address one of the new problems/limitations you have identified is enough.

Here are some final top tips for writing your discussion section:

• Don’t simply repeat your results section – remember your goal is to interpret and explain how your findings address the research problem.
• Be clear about what you have found, how this has addressed a gap in the literature and how it changes our understanding of your research problem.
• Structure your discussion in a logical way that highlights your most important/interesting findings first.
• Be careful about how you interpret your data: be wary over-interpreting to confirm a hypothesis. Remember, we can still learn from non-significant research findings.
• Avoid being apologetic or too critical when discussing the limitations of your research. Be concise and analytical.
