Question 3 Data Handling-Central Values Exercise 23.3

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

Answer:

First we have to arrange given data into ascending order

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

Given number of observations, n = 8 (even)

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

Median = (value of 4th term + value of 5th term)/2

= (31 + 35)/2

= 33

Hence median for given data = 33
