Explain each step that you would use to find the mean absolute deviation of a data set.

What is 1.) Find the mean of your data set (add all numbers, divide by the amount of numbers in your data set). 2.) Use your quotient (mean) and subtract that number from each number in your data set (if any numbers become negative, take away the negative sign). 3.) You should have a new data set, now find the mean of your new data set (add the numbers and divide by the amount of numbers in your data set). 4.) Your quotient (mean) is your mean absolute deviation.
