Question

question 4
in one study, it was found that the correlation coefficient between
two variables is -0.32.
which statement is true?
there is a weak negative association between the variables.
there is a strong negative association between the variables.
there is a weak positive association between the variables.
there is a strong positive association between the variables.

Explanation:

Step1: Analyze the sign of the correlation coefficient

The correlation coefficient \(r=- 0.32\). The negative sign (\(-\)) indicates a negative association.

Step2: Analyze the magnitude of the correlation coefficient

The magnitude of \(r\) is \(|r| = 0.32\). Generally, if \(0<|r|<0.5\), the association is considered weak.

Answer:

There is a weak negative association between the variables.
