snowball sampling

a method of selecting a SAMPLE by starting with a small selected group of respondents and asking these for further contacts. This is not therefore a RANDOM SAMPLE and no inferences about the characteristics of the parent population can be made from such a study. Its use is primarily in the collection of in-depth, qualitative data, perhaps on sensitive topics, where an obvious SAMPLING FRAME does not exist and the best method of selection is through personal contacts. Such a method might be used in an investigation of sexual habits or bereavement experiences.
