Quizplus · Accepted Answer

Multi-stage cluster sampling is suitable for Dr. Astley's study because it allows for the selection of groups (clusters) from a larger population in stages, which is practical when a complete list of all members of the population (in this case, all wait staff nationally) is not available.
