This is where you discuss your results and their significance. It often takes the form of a short essay within the report, and it is also usually where you demonstrate other skills like critical analysis and an ability to synthesise or combine lots of different pieces of information.

You might like to consider the following questions when thinking about content for your discussion:

What do your findings indicate?
Was anything surprising or particularly interesting?
Are the main claims/conclusions of the report supported by the
data collected and/or modelling?
If not, what other studies/analysis/experiments would be required?
Might anything have affected your results?
What has been learned?
What do your results show about the topic in general?

It may be appropriate to:

Link your discussion back to the introduction
Discuss how your findings vary from those of other researchers e.g. in the published literature
Indicate whether you have fully addressed the original research question or hypothesis
Evaluate your method – strengths and weaknesses of your approach, or your experiment design
Make suggestions or recommendations for action that should be taken as a result of your findings, or further research to be done. Sometimes, this is in a separate section titled 'Recommendations,' or may be incorporated into the 'Conclusion.'
