What is the shortest way to fine the "median" from above data. My result should be something like...
Median = 1/2(n+1), where n is the number of data values in the sample.

To find the median, calculate the mean by adding together the middle values and dividing them by two.
Median formula when a data set is even Determine if the number of values, n, is even. Locate the two numbers in the middle of the data set. Find the average of the two middle numbers by adding them together and dividing the sum by two. The result of this average is the median.
Take these two steps to calculate the mean: Step 1: Add all the scores together. Step 2: Divide the sum by the number of scores used.
Python 3.4 includes statistics built-in, so you can use the method statistics.median:
>>> from statistics import median
>>> median([1, 3, 5])
