Question

Quizplus · Accepted Answer

When it is impossible or impractical to compile a list of elements in a population, a cluster sample is appropriate. This technique involves dividing the population into clusters or groups and then randomly selecting some of those clusters to be included in the sample. Within each selected cluster, all individuals are included in the sample. This method can be cost-effective and time-efficient, particularly when the population is large and widely dispersed, such as all residents in a particular state or country.
