Question
Find the median of the following data (1-8)
31 , 38, 27, 28, 36, 25, 35, 40
Solution
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`
