The "mean" of a set of numbers is the average of the numbers.
For example, if the numbers are 6, 72, 34, 16, and 10, the "mean" is:
(6+72+34+16+10)
_______________ = 27.6
5
The "median" is the number in the middle when the numbers are listed from smallest to biggest. For example, list the numbers like this:
6, 10, 16, 34, 74 The median is the number in the middle, so here it is 16.
Half of the numbers in a data set are bigger than the "median" and half are smaller.
I hope that helps!
