Answer:
The mean absolute deviation is 15
Step-by-step explanation:
First you have to find the mean, which in this case is 147.
Then you need to find the difference between each individual number and the mean. Once you have all the diffences written down, you need to add all the differences together. If you take the sum of the differences and divide them by the mean, you'll get your answer!
Let me know if that makes sense! :)
