Question

which correlation coefficient represents a moderate negative correlation?
○ r = -0.94
○ r = -0.64
○ r = -0.24
○ r = -0.04

Explanation:

The correlation coefficient $r$ ranges from - 1 to 1. A value close to -1 indicates a strong negative correlation, a value around 0 indicates little to no correlation, and values between -0.5 and -0.3 (approximate) represent a moderate negative correlation. Among the given options, $r = - 0.64$ is in the range that can be considered a moderate negative correlation.

Answer:

$r=-0.64$
