What is the mean absolute deviation (MAD) of the data set? Round your answer to the nearest tenth, if necessary. {9.1, 9.3, 9.1, 9.5, 9.8, 9.9}

Hello there, and thank you for posting your question here on brainly.

Ok, to find MAD, you have to add up all of the decimals in the set, and then divide by how much decimals there are in the set.

Adding them all up...

The final result of the adding is 56.7

Now, we have to divide by how much decimals.

We now have. 56.7 / 6

Do the division.

56.7 / 6 ===> 9.45

No need to round, the final answer is 9.4

Hope this helped!! ☺♥
