Question

For which type of study is it most appropriate to use a random sample?

A) Random sample
B) Sample
C) Cluster
D) Population

Answer 1

The answer is A.

Stratified sampling techniques are generally used when the population is heterogeneous, or dissimilar, where certain homogeneous, or similar, sub-populations can be isolated (strata). Simple random sampling is most appropriate when the entire population from which the sample is taken is homogeneous.
