Rationale 1: Samples of 5,000 or 6,000 are often sufficient to estimate the characteristics of the entire population of the United States.
Rationale 2: The researcher should set a sample size minimum, but this one is probably too low to generalize to the entire United States.
Rationale 3: This would not be an effective way to ensure generalizability.
Rationale 4: The more homogeneous a sample is, the less generalizable the results are to a larger population.

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.
