The value of spearman's rank correlation coefficent no of observations was found to be 2/3. The sum of the squares of differences between the corresponding ranks was 55. Find the no. of pairs.
Dear Student
As we know
Where
rk = Coefficient of rank correlation
D = Rank differences
N = Number of pairs
Given -
rk = 2/3
ΣD2 = 55
N = ?
