Example 1:

Find the median of 12, 34, 8, 16, 25, 3 and 10

Arrange the data in an increasing order.

3, 8, 10, 12, 16, 25, 34

The middle number is 12

What is the median?

Example 2:
Find the median of 5, 14, 22, 35, 20, 15, 6 and 28
Arrange the data in an increasing order
5, 6, 14, 15, 20, 22, 28, 35
The middle numbers are 15 and 20
 $\frac{\left(15+20\right)}{\ 2}=17.5$
