C) It is not efficient
D) The participants may not produce the depth of information needed
D
Feedback:
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. However, convenience sample may be an economical way to begin the sampling process. Participants do meet the conceptual needs and that is why they are included.
