Quizplus · Accepted Answer

A significant correlation of -.40 can predict more accurately than a significant correlation of +.35 because the strength of a correlation is determined by the absolute value of the correlation coefficient, regardless of the sign. A correlation of -.40 (absolute value 0.40) is stronger than a correlation of +.35 (absolute value 0.35), indicating a stronger linear relationship between the variables.
