Question

The proportion of variance in one variable that is associated with variance in the other variable is given by. 
A) the coefficient of determination
B) $\sqrt { C P _ { X Y } }$
C) the index of association
D) $\sqrt { r }$

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, is a measure of how well the variation in one variable is explained by the variation in another variable. It ranges from 0 to 1, with a higher value indicating a stronger relationship between the variables. Therefore, A is the best choice. The other options are not valid measures of the proportion of variance associated with each other.
