Can Correlation Coefficient Be More Than 1. The significance of the relationship is provided in probability levels. A negative correlation signifies that as one variable increases the other tends to decrease.
The correlation coefficient is measured on a scale that varies from 1 through 0 to 1. The values range between -10 and 10. Note that from the formula on the page you link to the sample value of ρ s is 1 i 6 d i 2 n n 2 1.
Examples of scatter diagrams with different values of correlation coefficient ρ.
When one decreases as the other increases it is negative. As a matter of fact it cannot also be less than -1. Comparing Spearmans and Pearsons Coefficients. Correlation coefficient cannot be greater than 1.
