The median is simply the middle number of a group of data.For instance if you had 11 numbers 1,2,3,4,5,6,7,8,9,10,11; The median would be 6.  There are an equal number of data points above and below it.  1,2,3,4,5 [6] 7,8,9,10,11If there were and even number of numbers, 1,2,3,4,5,6,7,8,9,10; then you would take the average of the middle two numbers:  (5+6)/2 = 5 1/2.  1,2,3,4,5 [5 1/2] 6,7,8,9,10.If you are asking about an Excel formula, you can put the list of numbers in a column and then type in a cell "=MEDIAN(A1:A<to whatever the end of you list is>).  This will calculate it automatically.
