The methodology chapter of your dissertation should include discussions about the methods of data analysis. You have to explain briefly how you are going to analyze the primary data you will collect by employing the methods explained in this chapter.
There are differences between qualitative data analysis and quantitative data analysis. In qualitative research using interviews, focus groups, experiments among other. data analysis is going to involve identifying common patterns within the responses and critically analyzing them to achieve research aims and objectives.
Data analysis for quantitative studies, on the other hand, involves critical analysis and interpretation of figures and numbers and attempts to find the rationale behind the emergence of main findings. Comparisons of primary research findings to the findings of the literature review are critically important for both types of studies – qualitative and quantitative.
Data analysis methods in the absence of primary data collection can involve discussing common patterns, as well as, controversies within secondary data directly related to the research area.
