Median Part 1

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 {4, 7, 5, 6, 9}.

On arranging the numbers in ascending order, we have: 4, 5, 6, 7, 9.

So, the median is 6 as 6 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 {1, 4, 5, 4}.

On arranging the numbers in ascending order, we have: 1, 4, 4, 5

The two middlemost numbers are 4 and 4.
