= 0.60. If we change our measurements from cm to m, the new correlation will be
A) 0.06
B) 6
C) 0.006
D) none of these
E) 0.60

Question

Quizplus · Accepted Answer

The correlation coefficient (r) is a measure of the strength and direction of the linear relationship between two variables. Changing the units of measurement will not change the strength or direction of the relationship, so the correlation coefficient will remain the same. Therefore, the answer is E) 0.60.
