In Neyman allocation for stratified sampling, a larger sample is generally assigned to a stratum that has a larger:
Correct answer: C. Product of size and variability
- A. Population size only
- B. Within stratum variability only
- C. Product of size and variability
- D. Sampling frame code
Explanation
Neyman allocation considers both the size of a stratum and its within stratum standard deviation. Ignoring either factor can produce a less efficient allocation of the total sample.
