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...

In simple linear regression analysis, the coefficient of correlation (or correlation coefficient) is a statistic which indicates an association between the independent variable and the dependent variable. The coefficient of correlation is represented by “r” and it has a range of -1.00 to +1.00. ...
