Question

question 6 of 25
which of these r - values represents the weakest correlation?
a. - 0.35
b. - 0.75
c. - 0.15
d. - 0.05

Explanation:

Step1: Recall the rule of correlation strength

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

Step2: Calculate the absolute values

• For \(A\): \(| - 0.35|=0.35\)
• For \(B\): \(| - 0.75| = 0.75\)
• For \(C\): \(| - 0.15|=0.15\)
• For \(D\): \(| - 0.05|=0.05\)

Step3: Compare the absolute values

Since \(0.05<0.15 < 0.35<0.75\)

Answer:

D. -0.05
