An indication of no linear relationship between two variables would be:
A) a coefficient of determination equal to 1.
B) a coefficient of determination equal to -1.
C) a coefficient of correlation of 0.
D) a coefficient of correlation equal to -1.
E) Both "A" and "B" are correct.

Question

Quizplus · Accepted Answer

A coefficient of correlation of 0 indicates no linear relationship between the two variables. A coefficient of determination equal to 1 or -1 indicates a perfect positive or negative linear relationship, respectively, while a coefficient of determination between 0 and 1 indicates the proportion of the variation in one variable that can be explained by the other variable. Therefore, choices A, B, and D are incorrect in this scenario.
