Quizplus · Accepted Answer

The magnitude of the correlation coefficient reflects the strength of the linear relationship. Therefore, the absolute value of the correlation coefficient must be used when comparing strengths of a correlation. In this case, the absolute value of r =-.60 is 0.6, which is stronger than the absolute value of r=.40, which is 0.4. Therefore, r=-.60 is the stronger correlation.
