The coefficient of determination of an r = -.60 is
A) -.36.
B) +.36.
C) -.77.
D) None of these are true.

Question

Quizplus · Accepted Answer

The coefficient of determination is the square of the correlation coefficient, which means r^2 = (-.60)^2 = .36. The coefficient of determination represents the proportion of variation in the dependent variable that is explained by the independent variable(s). A value of .36 means that 36% of the variation in the dependent variable is accounted for by the independent variable(s). Since the coefficient of determination cannot be negative, choices A and C are incorrect.

The Coefficient of Determination of an R = -
