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