What does it mean when correlation coefficient is positive?
If correlation coefficient value is positive, then there is a similar and identical relation between the two variables. Else it indicates the dissimilarity between the two variables. The covariance of two variables divided by the product of their standard deviations gives Pearson’s correlation coefficient.
