Correct answer: (C) Representative of the population — To ensure accuracy, the sample should be representative of the population, so that is the answer.
Explanation
★To ensure accuracy, the sample should be representative of the population, so that is the answer.
★Accuracy means the sample results truly reflect the whole population.
★So the sample must be representative, mirroring the make-up of the population.
★A fixed quota filled by choice may not fairly reflect the population.
★A purposively chosen sample carries the researcher's own judgement and possible bias.
★A very small sample may miss the population's variety, so accuracy requires a representative sample.
