The coefficient of multiple determination (R2) shows________.
A) the effect of the control variable after removing the independent from the equation.
B) essentially the same thing as a partial gamma.
C) the combined effects of all independents on the dependent.
D) the zero-order relationships after controlling for the independents.

Question

Quizplus · Accepted Answer

The coefficient of multiple determination (R2) shows the combined effects of all independent variables on the dependent variable. It represents the proportion of variance in the dependent variable that can be explained by the independent variables in the model. Therefore, option C is the correct answer. Option A is incorrect as it refers to the effect of a single control variable, whereas R2 reflects the overall effect of all independent variables. Option B is incorrect as partial gamma is a measure of association between two variables, whereas R2 is a measure of the proportion of variance explained by all independent variables. Option D is incorrect as zero-order relationships refer to the correlation between two variables before controlling for other variables, whereas R2 accounts for the effect of all independent variables in the model.
