Why should a data sample be representative?

Answer and explanation

Correct answer: So that it can accurately reflect the characteristics of the target population

A representative sample reflects important characteristics of the target population, such as age, region, or relevant groups. Therefore, conclusions drawn from the sample can be generalized to the wider population more reliably. However, representativeness can reduce bias without completely eliminating every possible source of bias.
