Question

which r - value represents the strongest correlation?
-0.83
-0.67
0.48
0.79

Explanation:

Step1: Recall correlation - r - value concept

The strength of a correlation is determined by the absolute value of the correlation coefficient \(r\).

Step2: Calculate absolute values

\(\vert - 0.83\vert=0.83\), \(\vert - 0.67\vert = 0.67\), \(\vert0.48\vert = 0.48\), \(\vert0.79\vert=0.79\)

Step3: Compare absolute values

We compare \(0.83\), \(0.67\), \(0.48\), and \(0.79\). Since \(0.83>0.79 > 0.67>0.48\)

Answer:

\(-0.83\)
