""" MEDIAN
-> The Median is the middle value among all the values in sorted order. 
Here we need to calculate the mid-value of all the values in a dataset. 
But before calculating the Median, we need to arrange all the values in sorted order. 
There are two different ways of calculating the median value:
1. when the total number of values is even: Median  = [(n/2)th term + {(n/2)+1}th]/2
2. when the total number of values is odd: Median = {(n+1)/2}thterm
