Four different predictor variables A, B, C, and D) were measured. The researcher used the Pearson correlation coefficient to assess the relationship of each variable with the dependent variable. The resulting coefficients are summarized in the following table.
$$\begin{array} { c c c }

\end{array}$$
-Which predictor variable A, B, C, or D) has the strongest relationship positive or negative) with the dependent variable?
A) Variable B
B) Variable A
C) Variable D
D) Variable C

Quizplus · Accepted Answer

Variable B has the strongest relationship with the dependent variable, as indicated by the highest absolute value of the Pearson correlation coefficient (r = -0.98), which also results in the highest r² value (0.96), indicating a very strong linear relationship.
