Qualitative research: Part three - Methods

Background: There are still many practitioners, academics and researchers who are bemused by the principles and practices of qualitative research. In the third and final article in this three part series, I look at sampling in qualitative studies, methods of data collection and analysis. Content: Building on the previous two articles, I highlight the importance of rigour and explore some of the different criteria used by researchers to demonstrate that their research is trustworthy. I include a brief discussion of some of the more recent trends in mixed-method or post-positivist research. Conclusions: Qualitative research is different in many ways to quantitative, and it cannot be approached with the same mind-set. It seeks to explore different aspects to quantitative research, focusing on the individual experience, rather than conclusions that can be drawn from large groups. Because of these differences, the two approaches to research should not be seen as alternatives, but complementary.
