Multiple Choice
A standardized multiple regression equation yields a beta weight of 0.65 for X1 and -0.50 for X2. Which of the following is an interpretation of X1's beta weight?
A) A one standard deviation change in X1 is associated with a 0.65 standard deviation in Y, controlling for the effect of X2.
B) A one unit change in X1 is associated with a 0.65 standard deviation in X2, controlling for the effect of Y.
C) A one standard deviation change in X2 is associated with a 0.65 standard deviation change in Y, controlling for the effect of X1.
D) There is an error in this equation: beta-weights for X1 and X2 cannot have opposite signs.
