Explanation
★A representative sample is essential in the survey method, so that is the answer.
★A survey studies a sample in order to generalize to the whole population.
★So the sample must fairly represent the population, or the generalization will be wrong.
★The experimental method studies effects under control and does not chiefly aim to represent a population.
★The case study examines one unit deeply, not a representative sample.
★The clinical method studies individuals in depth, so a representative sample is essential in the survey method.
