In ................. sampling method, researcher requests respondents to help identify other potential respondents

  • A.Quota
  • B.Convenience
  • C.Snowball
  • D.Purposive

Answer: C

The method is snowball sampling.

In snowball sampling the researcher starts with a few respondents and asks each of them to name or recruit others who fit the study, so the sample grows like a rolling snowball. It is used for populations that are hard to reach or have no list, such as rare specialists or hidden groups.

Quota sampling fills fixed numbers from each category, convenience sampling takes whoever is easily available, and purposive sampling has the researcher choose respondents by judgement. None relies on respondents recruiting others.
