Snowball sampling technique pdf

Snowball Sampling. Snowball sampling isn’t one of the common types of sampling methods but still valuable in certain cases. It is a methodology where researcher recruits other individuals for the study. This method is used only when the population is very hard-to-reach.

Snowball sampling is a recruitment technique in which research participants are asked to assist researchers in identifying other potential subjects. The use of currently enrolled research participants to recruit additional research participants (sometimes referred to as “the snowball sampling”) may be approved by the IRB under some circumstances. However, the protocol must include

i. Snowball sampling (also called network, chain referral, or reputational sampling) is a method for identifying and sampling the cases in a network. It begins with one or a few people or cases and spreads out on the basis of links to the initial cases. b. Probability Sampling i. A sampling technique in which each unit in a population has a

Aug 07, 2018 · Qualitative researchers can also use snowball sampling techniques to identify study participants. In snowball sampling, a researcher identifies one or two people she’d like to include in her study but then relies on those initial participants to help identify additional study participants. Thus, the researcher’s sample builds and becomes
