Question

Quizplus · Accepted Answer

A high correlation coefficient (either positive or negative) indicates that there is a high level of consistency in the relationship between the two variables. This means that a change in one variable is likely to cause a corresponding change in the second variable. A third variable may still be responsible for the relationship, but a high correlation coefficient suggests that the two variables are closely related. Choices A and C are incorrect because a high correlation coefficient does not necessarily indicate that a third factor is responsible for the relationship, nor does it suggest that the scores on the two variables are identical.
