-Which predictor variable A, B, C, or D) has the most positive relationship with the dependent variable?
A) Variable C
B) Variable A
C) Variable B
D) Variable D

Quizplus · Accepted Answer

Variable A has the highest positive Pearson correlation coefficient (r = 0.30) among the variables, indicating the most positive relationship with the dependent variable.
