How does snowball sampling differ from simple random sampling as described in the chapter?
Snowball sampling differs from simple random sampling in that it relies on existing study participants to recommend future participants, creating a chain of referrals. In contrast, simple random sampling uses a random-number generator to select participants independently from the entire population.
Key points
- Snowball sampling involves referrals from current participants.
- Simple random sampling selects participants using a random-number generator.
- Snowball sampling can help reach hard-to-access populations.
- Simple random sampling aims for equal probability of selection from the population.
