Which sampling method would be most practical and provide the most reliable data to study the ethical conflicts experienced by registered nurses who work in city, county, and federal prisons?

Question

1. Purposive sampling.
2. Cluster random sampling.
3. Quota sampling.
4. Simple random sampling.

Answer 1

2
Rationale 1: Although purposive sampling may be practical, the data obtained will likely be biased.
Rationale 2: Cluster random sampling would be the most practical and yield the most reliable data because systematic selection of location for participants will improve reliability of data, and because the volume and locations of city, county, and federal prisons presents an impractical, expensive, and time-consuming approach.
Rationale 3: Although quota sampling may be practical, it will yield results drawn from a convenience sample.
Rationale 4: Although simple random sampling will yield reliable data, it is impractical because of volume and location.
