How do I find mean average deviation?

1.  First find the mean by adding all the numbers and dividing the sum by the amount of numbers.
2.  Subtract the mean from each number in the data set.
3.  Use absolute value to represent the distance of each difference.  This makes them all positive.
4.  Add all those numbers together and then divide by the amount of numbers in the data set.
