Question 8 Data Handling-Central Values Exercise 23.3

92, 35, 67, 85, 72, 81, 56, 51, 42, 69

Answer:

First we have to arrange given data into ascending order,

35, 42, 51, 56, 67, 69, 72, 81, 85, 92

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

= (67 + 69)/2

= 68

Hence median for given data = 68
