Semipartial Correlation Coefficient

A semipartial correlation coefficient is the correlation between variable A and variable B after controlling for other variables’ relationships with variable B. It is also called a part correlation. The semipartial correlation coefficient is useful to understand relationships between predictors in a multiple regression and the criterion variable. Because the correlation between one predictor and the criterion used in regression analyses is actually the semipartial correlation, we can see the independent relationship between each predictor and the criterion after controlling for other predictors’ overlap with that predictor.

A squared, semipartial correlation coefficient can be used in connection with multiple regression analysis to measure the strength of the association between the dependent and an independent variable, taking into account the relationships among all the variables. A squared ...
