Question 6 • CR02201A Probability and Statistics

Which gives the best definition of a representative sample?

Answer
A
An entire population.
B
A sample that has the same general characteristics of the target population.
C
A sample that does not fairly represent a given population.
D
Any part of a population.

Explanation

A representative sample reflects the important, general characteristics of the population it is intended to describe. That makes the sample’s results more useful for drawing conclusions about the whole population. Choice B, “a sample that has the same general characteristics of the target population,” gives this definition.
