Snowball Sampling
|
Detailed explanation-1: -Snowball sampling is used when researchers have difficulty finding participants for their studies. This typically occurs in studies on hidden populations, such as criminals, drug dealers, or sex workers, as these individuals tend to be difficult for researchers to access.
Detailed explanation-2: -"Snowball” sampling: in this case, the researcher selects an initial group of individuals. Then, these participants indicate other potential members with similar characteristics to take part in the study.
Detailed explanation-3: -There is no specific formula for snowball sampling in research. If you adopt the linear sampling method, then each of the existing variables would have to provide one possible research participant. For the exponential methods, existing variables can identify as many possible participants as they can find.
