Question

It uses only those questions that are important.

It tends to support valid inferences.

It produces the smallest number of people to survey.

It allows people to volunteer for the survey.

Answer 1

The correct answer is: It tends to support valid inferences.

Random sampling helps to ensure that the sample selected for the survey is representative of the larger population, which allows for more accurate and reliable results. This in turn supports valid inferences that can be generalized to the population as a whole. Using random sampling also helps to minimize bias and increase the likelihood of obtaining a diverse range of responses.
