        There is no mathematical formula for the Median.  It is performed
mechanically as follows:

Given a "random" series of an odd set of numbers:

        1, 5, 3, 10, 4

the median is:

1, 3, 4, 5, 10
      ^
or 4.  It is the middle number of the sorted list.

Given a "random" series of an even set of numbers:

        1, 5, 6, 4, 10, 9

the median is:

1, 4, 5 , 6, 9, 10
        ^
or 5 + (6-5)/2 = 5.5  It is the average of the center most number of the
sorted list plus the left most digit.
