Question

question 8 of 10
which of these r - values represents the strongest correlation?
a. - 0.7
b. - 0.6
c. - 0.8
d. - 0.5

Explanation:

Step1: Recall the rule for correlation coefficient

The strength of a correlation is determined by the absolute value of the correlation coefficient \(r\). The closer \(|r|\) is to \(1\), the stronger the correlation.

Step2: Calculate the absolute values

For option A: \(|-0.7| = 0.7\)
For option B: \(|-0.6| = 0.6\)
For option C: \(|-0.8| = 0.8\)
For option D: \(|-0.5| = 0.5\)

Step3: Compare the absolute values

Since \(0.8>0.7>0.6>0.5\)

Answer:

C. -0.8
