Question

which r value shows the strongest correlation? -0.98 -0.20 -0.25 -0.75

Explanation:

Step1: Recall correlation strength rule

The strength of a correlation is determined by the absolute value of the correlation coefficient $r$, where values closer to $1$ or $-1$ indicate a stronger correlation.

Step2: Calculate absolute values

$\vert -0.98 \vert = 0.98$, $\vert -0.20 \vert = 0.20$, $\vert -0.25 \vert = 0.25$, $\vert -0.75 \vert = 0.75$

Step3: Compare absolute values

$0.98 > 0.75 > 0.25 > 0.20$

Answer:

-0.98
