The formula for the Pearson’s r is complicated, but most computer programs can quickly churn out the correlation coefficient from your data. In a simpler form, the formula divides the covariance between the variables by the product of their standard deviations....
a value of ± 1 indicates a perfect degree of association between the two variables. On the other hand, as the correlation coefficient value goes towards 0, the relationship between the two variables will be weaker. Additionally, the sign of the coefficient indicates direction of the relationship...
