Flashcards
Snowball Sampling
Snowball Sampling
A non-random sampling method where existing study subjects recruit future subjects from among their acquaintances. Useful for reaching populations that are hard to find or reluctant to participate.
Subject Recruitment
Subject Recruitment
Initial subjects recruit additional subjects.
Study Notes
- Researchers start by recruiting initial subjects.
- Initial subjects then recruit additional subjects.
- Those additional subjects also recruit more subjects, and so on.
