Question 7 Data Handling-Central Values Exercise 23.3

12, 17, 3, 14, 5, 8, 7, 15

Answer:

First we have to arrange given data into ascending order,

3, 5, 7, 8, 12, 14, 15, 17

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

= (8 + 12)/2

= 10

Hence median for given data = 10
