Final answer:
The five-chapter format for theses and dissertations separates the discussion from the results section, which is often combined in other formats.
Step-by-step explanation:
In particular, the dissertation is the documentation of complete research paper with five main chapters: introduction, literature review, method, results, and discussion. The five-chapter format for theses and dissertations differs from the four-chapter model in that a separate chapter is devoted entirely to the discussion. This is in contrast to some formats where the results and discussion sections may be combined into a single chapter.
In the five-chapter format, results are presented upfront, typically with the aid of tables and graphs, but without the interpretation, which is reserved for the subsequent discussion chapter. In the discussion chapter, researchers interpret the results, explore the relationships between variables, and contextualize the findings within the existing scientific literature, usually with proper citations.
