    Given : the value of n(n²-1) is six time value of ∑d²  

    To Find : the value of r

    Solution:

    rank correlation coefficient   r  = 1   – 6  ∑ (di)² / (n(n² – 1))

    n = numbers  

    ∑ (di)²  = sum of squares of the differences in ranks  

    r = rank correlation coefficient  

    Now its given that  n(n²-1) is six time value of ∑d²

    => n(n²-1)  = 6 ∑d²

    Substituting value in formula

    r  = 1   – 6  ∑ (di)² / (n(n² – 1))

    => r  = 1 – 6 ∑ (di)²  / 6 ∑d²

    => r = 1  – 1

    => r = 0

    value of r is 0
