A data set has six values: 10,12,21,26,26,26 . What ranks would be assigned to 26 ?

A. 4,5,6
B. 4,4,4
C. 5,5,5
D. 5.5,5.5,5.5

Solution

as 26 are at 4th , 5th and 6th position

therefore:

we take the mean of these rank and can aassign this to them:

so the answer = mean rank =(4+5+6)/3

=5

so the rank will be: 5,5,5
