All research will need to be described logically in terms of typologies or categories or other devices. Examiners will be concerned not only with the accuracy and precision of the descriptions, but also with the ideas about relationships. The logic of the arguments about relationships will be a key concern here. Students who are writing about correlation and causation should have a firm understanding as to what those kinds of relationships involve and how the presence of causation is demonstrated. Here too the logic of the arguments will be of great interest to the examiners.
Style is about the overall 'neatness' of the presentation.
It is expected that students will write succinctly and crisply without undue waffle or redundancy. At the macro-level, the reader will be concerned with way chapters and other major units of the presentation fit together. While there is a huge range in personal taste and preference with regard to writing, there is general agreement concerning the norms of clarity. Writing is a craft, and it is expected that students will make some effort to craft their prose. At the micro-level, verbs should be appropriate in terms of the nouns or subjects they accompany.
