Question

question 17 of 25
which of these r - values represents the weakest correlation?
a. - 0.55
b. - 0.75
c. - 0.35
d. - 0.15

Explanation:

Step1: Recall the rule of correlation strength

The strength of a correlation is determined by the absolute value of the correlation coefficient. The closer the absolute value is to \(0\), the weaker the correlation.

Step2: Calculate the absolute values

For option A: \(| - 0.55|=0.55\)
For option B: \(| - 0.75| = 0.75\)
For option C: \(| - 0.35|=0.35\)
For option D: \(| - 0.15|=0.15\)

Step3: Compare the absolute values

Since \(0.15<0.35<0.55<0.75\)

Answer:

D. - 0.15
