Which of these is not a possible r-value?

A. 0.25

B. 1.5

C. - 0.1

D. - 0.75

The correct option is B.

Step-by-step explanation:

Here, r presents the Pearson correlation coefficient. The value of r lies from - 1 to 1.

If r=-1 or near to - 1, then it represents strong negative relation between two variables.

If r is near to - 0.5, then it represents weak negative relation between two variables.

If r=0, then it represents no relation between two variables.

If r is near to 0.5, then it represents weak positive relation between two variables.

If r=1 or near to 1, then it represents strong positive relation between two variables.

Since the value of r can't be less than - 1 and more than 1, therefore option B is correct because 1.5>1.

R value ranges from - 1 (perfect negative correlation) to 1 (perfect positive correlation). So, the value 1.5 is out of range and it can't be a possible r value.
