Question

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

Explanation:

Step1: Understand correlation strength

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

Step2: Calculate absolute - values

Calculate the absolute - value of each given \(r\) value: \(|-0.92| = 0.92\), \(|-0.18|=0.18\), \(|0.56| = 0.56\), \(|0.83| = 0.83\).

Step3: Identify moderate correlation

Among these, the \(r\) - value with an absolute - value in the moderate range (0.3 - 0.7) is 0.56.

Answer:

0.56
