Mean= The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
Median= The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first.
For example:
take the set 1,2,5,4,2,3,7,4,1
Mean/average=
(1+2+5+4+2+3+5+4+1)
 = 3
9
Median= 1,1,2,2,3,4,4,5,5 so the middle number would be 3.
Now which do you think better represents the set of data?
