Illustration of Rank Correlation Coefficient
Sometimes numerical data such refers to the quantifiable variables may be described after which a rank correlation coefficient may be worked out.
Is such a condition, the rank correlation coefficient will be determined after the described variables have been converted into ranks. See the given illustration:

Σd2 = 43.5
∴ Rank correlation r = 1 - {(6Σd2)/ (n (n2 -1))}
= 1 - {(6(43.5))/(10(102 -1))}
= 1 - (261/990)
= 0.74 as High positive correlation among mathematics marks and accounts
