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?

.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)
