The conclusion is the last chapter in your thesis and it synthesises the key aspects of your research.
The purpose of the conclusion is not simply to close off the research study, but also to open up new avenues for further research. You could see the research project as a funnel, starting with a broad contextualisation in the introduction and literature review, narrowing down with a description of your research interest and a discussion of the data, and broadening outward with a discussion of implications for existing body of knowledge on the topic.
The conclusion could cover some of the following:
- Summary of key ideas, themes and findings
- Discussion of how they address the research questions, and contribute to the body of knowledge
- Return to the key argument / hypothesis
- Presentation of recommendations for further research
