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:

A. (-0.83)
