E. SNOWBALL SAMPLING

E. Snowball Sampling

does not give a specific set of samples, similar to snow expanding widely or rolling rapidly. This is true for a study involving unspecified group of people. Dealing with varied groups of people such as street children, drug dependents, gang members, informal settlers, street vendors, and the like is possible in this kind of non- probability sampling.

A snowball sample is achieved by asking a participant to suggest someone else who might be willing or appropriate fro the study.
