In the Fourth Edition of this bestselling book, John W Creswell and new co-author Cheryl N Poth explore the philosophical underpinnings, history and key elements of each of five qualitative inquiry traditions: narrative research, phenomenology, grounded theory, ethnography and case study - putting them side by side, so that we can see the differences. The authors relate research designs to each of the traditions of enquiry. They compare theoretical frameworks and ways to employ standards of quality, as well as strategies for writing introductions to studies, collecting data, analyzing data, writing a narrative and verifying results.
