Below are the distances that each of Davi the Dragon Keeper's four dragons can blow fire (in meters). 0.9, 0.5, 0.3, 1.1. Find the mean absolute deviation (MAD) of the data set.

Step-by-step explanation:

          0.3, 0.5, 0.9, 1.1

I added a PowerPoint that I made so that if you didn't understand it you could read off of it.

Step-by-step explanation:

The answer is because, , so is the mean. After having found the mean, we have to subtract from the numbers, or the numbers from :

Data Point    |   Distance from the mean

                 |    

                 |    

                 |    

                 |    

After finding out the Distance from the mean we'll use their sums and add them all up: , then divide them by because there are numbers combined together: .

So that's why the answer is (Happy Valentines Day!)
