Question details
A researcher conducts a standard multiple regression analysis to predict weight loss as a function of the following predictors: eating habits (sr squared = .20), exercise habits (sr squared = .10), and gender (sr squared = .30). If the total variance accounted for in the dependent measure is 60%, what is the partial correlation squared for eating habits?
a. 
.50 (i.e., .20 / .40) 

b. 
Cannot be computed without knowing the shared variance. 

c. 
.33 (i.e., .20 / .60) 

d. 
.20 (i.e., .20 / 1.00)
