which of these is not a possible r - value?\na. 0.2\nb. 1.75\nc. -0.1\nd. -0.5
Answer
Explanation:
Step1: Recall the range of r - value
The correlation coefficient (r) has a range of (- 1\leq r\leq1).
Step2: Check each option
- Option A: (0.2) is between (-1) and (1).
- Option B: (1.75>1), so it is not in the range of possible (r) - values.
- Option C: (-0.1) is between (-1) and (1).
- Option D: (-0.5) is between (-1) and (1).
Answer:
B. 1.75
