Question

Quizplus · Accepted Answer

Multiple regression would be the most useful statistical method to predict success in graduate school on the basis of three variables: undergraduate G.P.A., IQ, and professor ratings. Multiple regression analyzes the relationship between a single dependent variable (success in graduate school) and multiple independent variables (undergraduate G.P.A., IQ, and professor ratings), allowing us to determine the unique contribution of each independent variable to the dependent variable while controlling for the effects of the other independent variables. Bivariate correlation and Spearman's rho can only analyze the relationship between two variables, and factor analysis is used to identify underlying factors that explain the pattern of correlations among multiple variables.
