Median = L + I *(N/2 - F)/f
where:
L = lower limit of the interval containing the median
I = width of the interval containing the median
N = total number of respondents
F = cumulative frequency corresponding to the lower limit
f = number of cases in the interval containing the median
OR
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] 7,8,9,10,11
If 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.
