All positive correlations predict with a higher level of accuracy than do all negative correlations.

Question

Quizplus · Accepted Answer

This statement is false. The strength of a correlation, whether positive or negative, is determined by its coefficient value (r), which can range from -1 to +1. A correlation coefficient of -0.7, indicating a strong negative relationship, would be just as predictive as a coefficient of +0.7, indicating a strong positive relationship.
