Two variables are said to have a correlation when scores on one variable:

A) are unrelated to the scores on the second variable.
B) are related to scores on the second variable.
C) cause the scores on the second variable.
D) are different from the scores on the second variable.


Answer: B
Rationale: When two variables are related so that the value of the first variable is associated with the value of the second, the two variables are said to be correlated. This does not necessarily mean that the first variable causes the value of the second variable—an important concept in correlational research is that correlation is a measure of association, not a measure of causality.
