If two correlated variables each have a bivariate correlation of .25 with a third variable,then the multiple correlation of the three variables combined will be .50.

Quizplus · Accepted Answer

Correlation between two variables does not directly indicate the multiple correlation between all three variables. The true multiple correlation would depend on the strength and direction of the correlation between the two variables, as well as the unique variance each variable contributes to the third variable. It is possible for the multiple correlation to be greater or less than .50 in this scenario.
