which r-value represents the strongest correlation?\n-0.83\n-0.67\n0.48\n0.79

Explanation:

Step1: Recall correlation strength rule

Correlation strength depends on the absolute value of $r$; values closer to $1$ or $-1$ are stronger.

Step2: Calculate absolute values

$|-0.83|=0.83$, $|-0.67|=0.67$, $|0.48|=0.48$, $|0.79|=0.79$

Step3: Compare absolute values

$0.83 > 0.79 > 0.67 > 0.48$

Answer:

-0.83
