The value r = -0.64 represents a moderate negative correlation because for moderate negative correlation r should close to -0.50 option third is correct.
What is correlation?
It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have correlation coefficient:
r = –0.04
r = –0.24
r = –0.64
r = –0.94
As we know, if r = 1 shows a perfect correlation
r = -1 (perfect negative)
For moderate negative correlation
r should close to -0.50
Thus, the value r = -0.64 represents a moderate negative correlation because for moderate negative correlation r should close to -0.50
