The rationale for selecting comparision groups is their theoretical relevance for fostering the development of emergent categories. If the analyst has collected his own data, In large field Chapter 7 Analysing the Data Material Using the Constant Comparative Analysis Method and D-Analysis Chapter 8 Quality and Ethics. Memo writing on the field note provides an immediate The constant comparative technique is used to find consistencies and differences, with the aim of continually refining concepts and theoretically relevant categories. The constant comparative method of joint coding and analysis, which uses explicit coding and analytic procedures, is designed to generate theory more systematically than the second approach allows. See Allen H. Barton and Paul F.

Constant comparison is the data-analytic process whereby each interpretation and finding is compared with existing findings as it emerges from the data analysis. analyzing before writing about it. Open coding is when you take your transcripts, and break it into individual excerpts. The constant comparative method is an inductive data coding process used for categorizing and comparing qualitative data for analysis purposes. The data is constantly revisited after initial coding, until it is clear that no new themes are emerging. New York: Aldine DeGruyter. Publishing Co., 1967).

In this iterative process, purposeful sampling is used to solicit data variations that cover all sides of a topic.
