Question

Quizplus · Accepted Answer

The correlation coefficient (r) ranges from -1 to 1. A value of -1 indicates a perfect negative correlation, while a value of 1 indicates a perfect positive correlation. A value of 0 indicates no correlation. The strength of the correlation is determined by the absolute value of r, regardless of the sign. Therefore, r = -.8 shows the strongest correlation among the options because its absolute value (.8) is the highest.
