Question

Quizplus · Accepted Answer

This ensures that the conclusions drawn from the sample will be valid for the larger population. Choices A and B are incorrect because the control group and confederates are not involved in sample selection. Choice C is incorrect because including the entire group (i.e., population) is often impractical or impossible, so a representative sample is used instead.
