Question

question 22 of 25
which of the following is not a possible r - value?
a. - 1.3
b. 0.3
c. - 0.6
d. 0.6

Explanation:

Step1: Recall the range of the correlation coefficient \(r\)

The correlation coefficient \(r\) satisfies the inequality \(- 1\leqslant r\leqslant1\).

Step2: Check each option against the range

• Option A: \(-1.3\) is not in the range \([-1,1]\)
• Option B: \(0.3\) is in the range \([-1,1]\)
• Option C: \(-0.6\) is in the range \([-1,1]\)
• Option D: \(0.6\) is in the range \([-1,1]\)

Answer:

A. -1.3
