A. Above-average values in one variable correspond to below-average values in the other variable.
B. Above-average values in one variable correspond to above-average values in the other variable.
C. Below-average values in one variable correspond to below-average values in the other variable.
D. Below-average values in one variable correspond either above-average or below-average values in the other variable.
