Question

Quizplus · Accepted Answer

This method can help provide a more accurate representation of the population being studied. Option B is incorrect because stratified sampling does not necessarily over-represent any particular minority group. Option C is also incorrect, as stratified sampling attempts to create equal probabilities of selection among individuals within each category.
