# Find the median of the data : 21, 15, 6, 25, 18, 13, 20, 9, 8, 12

**Solution:**

Given, the data is 21, 15, 6, 25, 18, 13, 20, 9, 8, 12

We have to find the median of the __data__

When the given data is arranged in ascending (or descending) order, then the middle most observation is the median of the data.

Arranging the data in __ascending order__, we get

6, 8, 9, 12, 13, 15, 18, 20, 21, 25

Number of observations, n = 10

If n is even, then __median__ = [(n/2)th term + (n/2 + 1)th term]/2

= [(10/2)th term + (10/2 + 1)th term]/2

= [5th term + 6th term]/2

= (13+15)/2

= 28/2

= 14

Therefore, the median is 14.
