Question

question 4 of 10
which of these r-values represents the weakest correlation?
a. 0.5
b. 0.3
c. 0.4
d. 0.2

Explanation:

The strength of a correlation is determined by the absolute value of the correlation coefficient \(r\). The closer the absolute value of \(r\) is to 0, the weaker the correlation. Comparing the absolute values of the given options: \(|0.5|=0.5\), \(|0.3|=0.3\), \(|0.4|=0.4\), \(|0.2|=0.2\). The smallest value is 0.2, so it represents the weakest correlation.

Answer:

D. 0.2
