Values closer to 0 show a strong linear relationship, The correlation coefficient ranges from - 1 to 1. Values close to +1 or -1 show a strong linear relationship. If the values of x and y are interchanged, the correlation coefficient remains the same. The value of the coefficient is resistant to outliers
