Question

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

Explanation:

Step1: Recall the rule of correlation strength

The strength of a correlation is determined by the absolute value of the \(r -\)value. The closer \(|r|\) is to \(1\), the stronger the correlation.

Step2: Calculate the absolute values

For \(r=-0.83\), \(|r| = 0.83\).
For \(r=-0.67\), \(|r|=0.67\).
For \(r = 0.48\), \(|r|=0.48\).
For \(r = 0.79\), \(|r|=0.79\).

Step3: Compare the absolute values

Since \(0.83>0.79>0.67>0.48\)

Answer:

\(-0.83\)
