+130511 how do u find the mean?
-----------------------------------------------------------------------------------------------------
The "mean" of a data set is just its average. An example may work better than a definition. Let's suppose we have four test scores and we're trying to find their average.
Let's say the scores are 60, 75, 85 and 100.
I just add them up and divide the sum by the number of scores we have.
So
(60 + 75 + 85 + 100) / 4 = (320 / 4 ) = 80.
And that's their average.
