How to find the median

KengaRu [80]

We can find the median by using the formula:

(N+1/2) th item

For example:

Given data: 4,6,3,5,7

We have to arrange the data into ascending order:

=3,4,5,6,7

N(total no of items)=5

Now,

Median=(N+1/2)th item

 =(5+1/2) th item

 =(6/2) th item

 = 3rd item

Median=5

Hope it helps
