Question

1. Search for participants who will disprove an emerging theory.
2. Try to obtain participants who are as similar to each other as possible.
3. Choose participants who can verify they will participate in this study, which will take several years to complete.
4. As new data are collected, compare them to the data that were collected previously.
5. Assign codes to pertinent identified data.

Answer 1

1,4, 5
Rationale 1: As hypotheses and theories emerge in a grounded study, the researcher may deliberately choose participants who might be able to disprove the emerging ideas.
Rationale 2: The researcher should choose diverse participants.
Rationale 3: These studies are not necessarily lengthy and an individual subject's participation may be rather short. Studies that take years to complete are longitudinal studies.
Rationale 4: Comparing data as they are collected is called the constant comparison method.
Rationale 5: As pertinent data are identified, codes are assigned. The codes are constantly reviewed as new interpretations are made of the data.
