Question

Which of the following statements about stratified samples and cluster samples is false?

		Both are used when there is no list of cases in the population
		Both require multiple random selections
		Both require multiple steps
		They are both considered random samples

Answer 1

We know that stratified samples and cluster samples require multiple random selection, so they are considered as random samples. Option B and D are true.

In stratified samples and cluster samples, we need to perform sampling in multiple steps, i.e. selecting clusters or strata and then selecting the sample. So, option C is also true

Option A is only false option because stratified samples and cluster samples cannot be selected without having no list of cases in the population. We need a list of cases to select the clusters and strata for respective sampling designs.

Therefore, option A is answer (false)
