If ages (in year) of some animals are 6, 10, 5, 4, 9, 11, 20, 18; let us find the median of ages.

To find median, it is necessary to arrange the data in either ascending or descending order.

So, let’s arrange the data into ascending order. It is,


4, 5, 6, 9, 10, 11, 18, 20


Note that, total number of data, n = 8


Here, n is even. When n is even, median is found out as



Putting n = 8, we get



⇒


⇒


⇒


⇒ Median = 9.5


Thus, median is 9.5.
