How to Find the Mean?

In math, to find the mean of a set of numbers, you simply need to take the average of this set. You find the mean by adding the numbers in the data set and dividing by how many numbers are in this set. For example, to find the mean of 10, 20, 30, you add these numbers to get 60 and divide by 3. The mean is 60/3 or 20. You can find more information here:
