Median is simply defined as the most middle value of an arranged data. It means that it divided the data into two equal portions.

**Formula**

Median = (n + 1 / 2) th value

**Example**

Find median of the following data:

7, 3, 8, 5, 6, 9, 11, 5, 18, 11

**Solution**

First, we will arrange the unarranged data as follows:

3, 5, 5, 6, 7, 8, 9, 11, 11, 18

Median = (n + 1 / 2) th value = (10 + 1 /2) th value = 5.5
