1 Mean Absolute Deviation September 25, 2013

2 Definition To find the mean absolute deviation, find the absolute values of the differences between each value and the mean. Then find the average of those differences.

3 Example Look at the 2 Line Graphs of the SUV Mileage and Small-Car Mileage. What are the values for the SUV Mileage? What is the mean for the SUV Mileage?

4 Small-Car Mileage What are the values for the Small-Car Mileage? What is the mean for the Small-Car Mileage?

5 Mean of the Differences Find the average for the SUV Mileage differences. Find the average for the Small-Car Mileage differences.

6 Inference Make an inference. What does the Mean Absolute Deviation tell us about this data?
