Question 2 Data Handling-Central Values Exercise 23.3

133, 73, 89, 108, 94,104, 94, 85, 100, 120

Answer:

First we have to arrange given data into ascending order,

73, 85, 89, 94, 100, 104, 108, 120, 133

Given number of observations, n = 10 (even)

Therefore median = (n/2)th term + ((n + 1)/2)th term

Median = (value of 5th term + value of 6th term)/2

= (94 + 100)/2

= 97

Hence median for given data = 97
