Formula:

R = 1 - ( (6× σd2) / (n3 - n) ) Where, σ = Sumation of differences d = Differences n = Number of Datas R = Rank Value

This online Spearman's rank correlation coefficient (RHO) calculator helps you to do Spearman's RHO calculation with ease. The correlation coefficient helps you in assessing the relationship between two variables in a monotonic function. The Sperman's correlation, named after Charles Sperman, between two variables is equal to the Pearson correlation between the rank values of those two variables. The correlation between two variables will be high when observations have a similar rank between the two variables and low when observations have a dissimilar rank between the two variables. Enter the number of sets and enter the values for the sets in this RHO calculator to know the ranks for the sets and the R value and conclusion whether it is a correlation value or not.

Example

R = 1 - ( (6× σd2) / (n3 - n) )
=1 - ( (6× 34) / (53 - 5) )
=1 - ( (204) / (120) )
R = - 0.7
From the below table , It is a strong negative correlation value

R Value Correlation Conclusion
-1 Perfect negative
between -1 and -0.5 Strong negative
between -0.5 and 0 Weak negative
0 No correlation
between 0 and 0.5 Weak positive
between 0.5 and 1 Strong positive
1 Perfect positive
