Median is the middlemost number in a set of numbers when the numbers are arranged in ascending or descending order.
For example: Consider the data {7, 4, 3, 8, 8}.
On arranging the numbers in ascending order, we have: 3, 4, 7, 8, 8.
So, the median is 7 as 7 is the middlemost number.
When the number count is even, we need to add both the middlemost numbers and divide the obtained result by 2.
For example: Consider the data {5, 9, 2, 6, 3, 4}.
On arranging the numbers in ascending order, we have: 2, 3, 4, 5, 6, 9
The two middlemost numbers are 4 and 5.
