Question

2 what is the main goal of designing a sampling plan?
a. to use all types of sampling methods in one study
b. to ensure the sample is large enough
c. to make data collection easier
d. to obtain a sample that accurately represents the population

Explanation:

Sampling plans aim to get a sample that mirrors the population. Using all sampling methods (a) isn't practical. A large sample (b) doesn't guarantee representativeness. Easier data collection (c) is a by - product, not the main goal. Representativeness (d) is key as it allows generalizing results from the sample to the population.

Answer:

d. To obtain a sample that accurately represents the population
