A correlation coefficient should not be regarded as a judgment; it is only a number summarizing the relationship of two sets of facts to each other. A coefficient's size is important, but the reason for its size is more important. A coefficient should be regarded as a clue to further investigation, which should include the test, the criterion (possibly grades or ratings), and the population, together considered the three legs of a correlation coefficient.
