Quizplus · Accepted Answer

C) -.80 represents the strongest association because correlation coefficients range from -1 to +1, where -1 indicates a perfect negative linear relationship, +1 indicates a perfect positive linear relationship, and values closer to -1 or +1 indicate stronger associations. -1.5 is not a valid correlation coefficient.
