Practice question · True or false
A carefully drawn random sample of 400 people can generalize to the population better than a self-selected convenience sample of 40,000.
Hints
- Weigh sampling METHOD against sheer sample SIZE.
- Bias in a convenience sample does not shrink just because the sample is huge.
Show the answer
True
Why
True. A smaller random sample can generalize better than a much larger convenience sample, because generalizability depends on unbiased selection, not on size. A huge self-selected sample keeps its bias no matter how many people it contains.
