# MEAN ABSOLUTE DEVIATION MAD Mean Add them all

MEAN ABSOLUTE DEVIATION *MAD*

Mean: Add them all up and Divide by the number of data Absolute: The distance from zero. Always a positive number! Deviation: How something is different. In this case, from the mean.

MEAN The mean of the data set is its average. 5, 8, 10, 12, 13, 14 Mean = 10. 71

Mean Absolute Deviation (MAD) The mean absolute deviation of a numerical data set is the average deviation of the data from the mean. What in the world is that?

How do I do that? ? Step 1: Find the mean Step 2: Subtract the mean from each data Step 3: Take the absolute value of each difference Step 4: Add it up and divide by the number of data (find the mean again!)

The numbers below are the golf scores for the UGA golf team. Find the mean absolute deviation of the data. 68, 70 , 72, 73, 74, 75 Step 1: Find the Mean Step 2: Subtract Value-Mean Step 3: Absolute Value (no neg sign) Step 4: Find the Mean Again!

Find the MAD of the following Florida State University 2013 Football scores: 41, 62, 54, 48, 63, 51, 49, 41, 59, 80, 37, 45, 31 Step 1: Find the Mean Step 2: Subtract Value-Mean Step 3: Absolute Value (no neg sign) Step 4: Find the Mean Again!

You Find the MAD of the following set of test scores. Try! 70, 73, 74, 81, 88, 89, 90, 92, 95, 96 Step 1: Find the Mean Step 2: Subtract Value-Mean Step 3: Absolute Value (no neg sign) Step 4: Find the Mean Again!
