Feedback:
Type of sampling strategy can change over the course of a study Qualitative sampling may begin with volunteer informants and may be supplemented with new participants through snowballing. Many qualitative studies, however, evolve to a purposive (or purposeful) sampling strategy in which researchers deliberately choose the cases or types of cases that will best contribute to the study. Sampling by convenience is efficient, but is not a preferred approach, even in qualitative studies. The aim in qualitative studies is to extract the greatest possible information from a small number of people, and a convenience sample may not provide the most information-rich sources. Qualitative researchers avoid random samples because they are not the best method of selecting people who will make good informants
