Question

Find the median of the following data (1-8)

31 , 38, 27, 28, 36, 25, 35, 40

Answer 1

Given numbers are 31, 38, 27, 28, 36, 35, 40
Arranging in increasing order
25, 27, 28, 31, 35, 36, 38, 40

n = (even)

∴ Median  = `(n^(th)/2 value + (n^(th)/2+1)value)/2`

               = `(8^(th)/2 value + (8^(th)/2+1)value)/2`

               = `(4^(th) value + 5^(th)value )/2`

                = `66/2 = 33`
