Question

2. Which correlation coefficient below shows the least amount of association between the two variables?

(1) r=0.92
(3) r=-0.98
(2) r=-0.54
(4) r = 0.28

Answer 1

(4) r = 0.28

Explanation:

The correlation coefficient represents the amount of association between two variables,

so, the higher the coefficient, the stronger the association,

and conversely, the lower the coefficient, the weaker the association

in our case, the least amount of association is given by the smallest number of the bunch,

Hence, since r = 0.28 is the smallest number, it shows the least amount of association between two variables
