How excatly do I calculate the average? Can somebody explain step by step process of how to get an average?

If I have an array of numbers (5, 3, 4, 3, 1) and so on. And I need to get the average of these numbers on a scale of 5 what is the equation of doing this?

    There are many [averages](http://en.wikipedia.org/wiki/Average). Regular average is known as arithmetic mean, obtain by summing elements of your array and dividing over its length.2011-08-23

To average a list of numbers, add up all the numbers and then divide by the size of your list.

For your example, we'd get $ \frac{5+3+4+3+1}{5} = \frac{16}{5} = 3.2. $
