Your dissertation will require you to collect some data in order to investigate your objectives (and research questions if you have them). This in turn calls for you to make informed decisions as to the type/s of data you need and how to collect them. Within the early development of your topic, you should ask yourself ‘what is/are the most appropriate method/s of data collection for my emerging research objectives?’. We have already touched on parts of this selection process where we started to discuss the key linkages within a dissertation (Chapter 2, Figure 2.1) and how to review the literature with an eye for methods (Chapter 4).
