Quizplus · Accepted Answer

A representative sample accurately reflects the characteristics of the population from which it is drawn. This means that the sample's demographics, behaviors, and attributes closely match those of the larger population, ensuring that findings from the sample can be generalized to the population. Homogeneity (A), including all units of a population (B), and using the most accessible subjects (C) do not necessarily ensure representativeness.
