Question

question 16 of 25
which of the following r-values represents the strongest correlation?
a. 0.55
b. 0.65
c. 0.45
d. 0.35

Explanation:

Step1: Understand the concept of correlation coefficient

The correlation coefficient \(r\) ranges from \(- 1\) to \(1\). The closer the absolute value of \(r\) is to \(1\), the stronger the correlation.

Step2: Compare the absolute values of the given \(r\)-values

For \(A\): \(|0.55| = 0.55\)
For \(B\): \(|0.65| = 0.65\)
For \(C\): \(|0.45| = 0.45\)
For \(D\): \(|0.35| = 0.35\)

Since \(0.65>0.55>0.45>0.35\)

Answer:

B. \(0.65\)
