Quizplus · Accepted Answer

The correlation coefficient indicates the strength and direction of the linear relationship between two variables. A correlation coefficient of -0.80 represents a strong negative relationship, indicating that as one variable increases, the other variable decreases in a predictable way. Therefore, A represents the greatest predictive relationship between two variables. A correlation coefficient of -0.40 represents a moderate negative relationship, while a correlation coefficient of 0.00 represents no relationship, and a correlation coefficient of 0.40 represents a moderate positive relationship.
