Use when you are studying diversity and seeking a wide range of views or different subjects.

Discussion

Some studies are broad rather then narrow and hence need to identify the widest possible set of subjects. Narrow studies seek to eliminate variation. Diversity studies seek to discover and understand variation.

The final sample size in such studies may not be determined, although a minimum size may be identified. More critical is sampling across a wide area of the population in order to maximize the chance of identifying the

Narrow studies may be preceded by wide, heterogeneous studies that help a second-stage study of

Diversity sampling is also known as Heterogeneity sampling.
