Answer:
mean (average) is 17.6
mean absolute deviation is 15.2
<em></em>
<em>Step-by-step explanation:</em>
to find <em>mean</em>, u add up all your numbers and divide by how many there are...
to find <em>mean absolute deviation</em> you find the mean of the data and subtract that amount to each of your data pieces...
then u find absolute value of each of them (to make them all positive)
then u add all of those numbers up and divide by how many there are, and that is your answer!!
<em>Hope this helps u in the future!!</em>
