Not all the time the Mean Absolute Deviation (MAD) will be whole numbers. And the reason it will not just be whole numbers because you have decimal when you are solving the equations of mad . Let me show you I did a lesson it my course not to long ago. This was on my test for (MAD) And I got it correct it was C. 6.4. And that is why you don't only have whole numbers but you have more things. Hope I could help. What is the mean absolute deviation of the data set?
{12, 4, 30, 16, 18}
2.856.416
