Question

which r - value represents the weakest correlation?
-0.75
-0.27
0.11
0.54

Explanation:

Step1: Recall correlation - r - value concept

The closer the absolute - value of the correlation coefficient (r - value) is to 0, the weaker the correlation.

Step2: Calculate absolute values

$|0.54| = 0.54$, $|0.11| = 0.11$, $|- 0.27| = 0.27$, $|-0.75| = 0.75$.

Step3: Compare absolute values

Among 0.54, 0.11, 0.27, and 0.75, 0.11 is the smallest.

Answer:

0.11
