Question

You conduct a standard multiple regression (SMR) analysis with two predictors (X1 and X2), which account for 30% of the variability in the criterion (Y).  However, the shared variance between X1 and X2 accounts for 20% of the variance in the DV.  If both IVs are entered together in a standard multiple regression, the coefficient for X1 will be __________ compared to the coefficient that X1 would produce if X1 was entered in Block 1 of a hierarchical multiple regression (HMR), with X2 entered in Block 2.

(a) unchanged

(b) it is impossible to say

(c) smaller

(d) larger

Answer 1

Solution is I both INS are Answer larger [option Cowest ] entered together in a standard multiple regression, the Coefficient for x, will be compared Compared larger to the Coefficient that y, would if X, was Enkred in Block of a hierarchical multiple regression (HMR) with X₂ Entered in Block 2 produce
