When writing a dissertation or thesis, the results and discussion sections can be both the most interesting as well as the most challenging sections to write.
You may choose to write these sections separately, or combine them into a single chapter, depending on your university’s guidelines and your own preferences.
There are advantages to both approaches.
You should cover any literature supporting your interpretation of significance. It does not have to include everything you did, particularly for a doctorate dissertation. However, for an undergraduate or master's thesis, you will probably find that you need to include most of your work.
You should write your results section in the past tense: you are describing what you have done in the past.
Every result included MUST have a method set out in the methods section. Check back to make sure that you have included all the relevant methods.
Conversely, every method should also have some results given so, if you choose to exclude certain experiments from the results, make sure that you remove mention of the method as well.
If you are unsure whether to include certain results, go back to your research questions and decide whether the results are relevant to them. It doesn’t matter whether they are supportive or not, it’s about relevance. If they are relevant, you should include them.
Having decided what to include, next decide what order to use. You could choose chronological, which should follow the methods, or in order from most to least important in the answering of your research questions, or by research question and/or hypothesis.
You also need to consider how best to present your results: tables, figures, graphs, or text. Try to use a variety of different methods of presentation, and consider your reader: 20 pages of dense tables are hard to understand, as are five pages of graphs, but a single table and well-chosen graph that illustrate your overall findings will make things much clearer.
Make sure that each table and figure has a number and a title. Number tables and figures in separate lists, but consecutively by the order in which you mention them in the text. If you have more than about two or three, it’s often helpful to provide lists of tables and figures alongside the table of contents at the start of your dissertation.
Summarise your results in the text, drawing on the figures and tables to illustrate your points.
The text and figures should be complementary, not repeat the same information. You should refer to every table or figure in the text. Any that you don’t feel the need to refer to can safely be moved to an appendix, or even removed.
Make sure that you including information about the size and direction of any changes, including percentage change if appropriate. Statistical tests should include details of p values or confidence intervals and limits.
While you don’t need to include all your primary evidence in this section, you should as a matter of good practice make it available in an appendix, to which you should refer at the relevant point.
For example:Details of all the interview participants can be found in Appendix A, with transcripts of each interview in Appendix B.
You will, almost inevitably, find that you need to include some slight discussion of your results during this section. This discussion should evaluate the quality of the results and their reliability, but not stray too far into discussion of how far your results support your hypothesis and/or answer your research questions, as that is for the discussion section.
See our pages: and Simple Statistical Analysis for more information on analysing your results.
This section has four purposes, it should:
- Interpret and explain your results
- Answer your research question
- Justify your approach
- Critically evaluate your study
The discussion section therefore needs to review your findings in the context of the literature and the existing knowledge about the subject.
You also need to demonstrate that you understand the limitations of your research and the implications of your findings for policy and practice. This section should be written in the present tense.
