Question

which r - value represents the most moderate correlation? - 0.92 - 0.18 0.56 0.83

Explanation:

Step1: Recall the correlation strength

The closer the absolute value of \(r\) is to \(1\), the stronger the correlation. The closer it is to \(0\), the weaker. Moderate correlation has an \(|r|\) value between \(0.3\) and \(0.7\).

Step2: Calculate absolute values

For \(r=- 0.92\), \(|r| = 0.92\).
For \(r=-0.18\), \(|r|=0.18\).
For \(r = 0.56\), \(|r|=0.56\).
For \(r = 0.83\), \(|r|=0.83\).

Step3: Compare

Among \(0.92\), \(0.18\), \(0.56\), \(0.83\), \(0.56\) is in the range of moderate correlation (\(0.3<|r|<0.7\)).

Answer:

\(0.56\)
