Find the median of the following data (1-8)
83, 37, 70, 29, 45, 63, 41, 70, 34, 54
उत्तर
Given numbers are
83, 37, 70, 29, 45, 63, 41, 70, 34, 54
Arrange the numbers is ascending order
29, 34, 37, 41, 45, 54, 63, 70, 70, 83
n = 10 (even)
∴ Median = `(n^(th)/2 value + (n/2 +1)^(th)value)/2`
=`(10^(th)/2 value + (10/2 +1)^(th)value)/2`
= `(5^(th) value + 6^(th) value)/2`
= ` (45 + 54)/2 = 99/2 = 49.5`
