Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviation of the number of cars? Round to the nearest tenth, if needed. A. 0.7 cars B. 1.1 cars C. 1.4 cars D. 2 cars
First you find the mean (add all the numbers then divide by how many numbers you have). Mean =2. To find the MAD subtract each number from the mean. Then add the absolute values (the number regardless of the sign) together, then divide by how many numbers you have. The answer then rounded to the tenth would be .7 :) I really hope this helps!
