Why is ‘r’ preferred to co-variance as a measure of association?

1.	Why is ‘r’ preferred to co-variance as a measure of association?
Answer» ‘r ’ is Perferred to co-variance as a measure of association because it studies and Measures the direction and intensity of relationship among variables. It is due to the following reasons: 1. The correlation co – efficient (r) has no unit. 2. The correlation co – efficient is independent of origin as well as a scale
