Question

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

Explanation:

Step1: Understand the concept of correlation coefficient ($r$ - value)

The correlation coefficient $r$ ranges from - 1 to 1. The closer $|r|$ is to 1, the stronger the correlation. The closer $|r|$ is to 0, the weaker the correlation. A moderate correlation has $|r|$ in the range of approximately 0.3 - 0.7.

Step2: Calculate the absolute values of the given $r$ - 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 the absolute values

We have $0.18<0.56<0.83<0.92$. The value of $|r| = 0.56$ (corresponding to $r = 0.56$) lies in the moderate correlation range (0.3 - 0.7).

Answer:

0.56
