Answer to Question 1

D
Feedback:
The objective of theoretical sampling is to discover categories and their properties and to offer new insights about interrelationships that occur in the substantive theory. Groups are chosen for their relevance in furthering the emerging conceptualization. These groups are not chosen before the research begins but only as they are needed for their theoretical relevance in developing emerging categories. Criterion sampling involves studying cases that meet a predetermined criterion of importance. Extreme (deviant) case sampling provides opportunities for learning from the most unusual and extreme informants (e.g., outstanding successes and notable failures). Snowball sampling is a method in which early participants recommend or refer additional participants.
