Answer to Question 1

Cluster sampling involves randomly selecting preexisting clusters or groups instead of randomly selecting individuals. The main advantages are (1) it is easy to obtain a large sample quickly, and (2) because the participants are already organized in groups, it is often easy and convenient to test them as a group. For example, you could hand out questionnaires to an entire class instead of giving questionnaires to one person at a time. The main concern with cluster sampling is that the individuals within a cluster may not be independent. If the clusters consist of families, for example, it is likely that all of the family members share some common interests and common experiences.
