The logic and power of probability sampling derive from statistical probability theory. A random and statistically representative sample permits confident generalization from a sample to a larger population. The logic and power of purposeful sampling lies in selecting _____ in depth.

Question

Quizplus · Accepted Answer

A. This is an incorrect answer because the logic and power of purposeful sampling lies in selecting information rich cases for study in depth, not in information for study. If researchers understand the principles and logic of more formal sampling methods, they are likely to produce more effective purposive sampling in field research.
B. The correct answer is "B" because the logic and power of purposeful sampling lies in selecting information rich cases for study in depth. If researchers understand the principles and logic of more formal sampling methods, they are likely to produce more effective purposive sampling in field research.
C. This is an incorrect answer because the logic and power of purposeful sampling lies in selecting information rich cases for study in depth not in information for non-probability samples. If researchers understand the principles and logic of more formal sampling methods, they are likely to produce more effective purposive sampling in field research.
D. This is an incorrect answer because the logic and power of purposeful sampling lies in selecting information rich cases for study in depth not in information for purposeful sampling. If researchers understand the principles and logic of more formal sampling methods, they are likely to produce more effective purposive sampling in field research.
