When information regarding two or more predictor variables is combined in order to predict performance on Y, then the appropriate statistical test is
A) the partial correlation
B) the Galton "g"
C) the Yates Correction
D) the multiple R

Question

Quizplus · Accepted Answer

The multiple R (also known as the multiple correlation coefficient) is used to measure the strength and direction of the linear relationship between two or more predictor variables and a single outcome variable (Y). It provides a measure of how well the set of predictor variables predict the outcome variable when used together. This is the appropriate statistical test when information from multiple predictors is combined to predict Y.
