Definition and Usage
The statistics.median() method calculates the median (middle value) of the given data
set. This method also sorts the data in ascending order before calculating the median.
Tip: The mathematical formula for Median is: Median = {(n + 1) / 2}th value, where n is the number of values in a set of data. In order to calculate the median, the data must first be sorted in ascending order. The median is the number in the middle.
Note: If the number of data values is odd, it returns the exact middle value. If the number of data values is even, it returns the average of the two middle values.
