Find the mean absolute deviation for the data set.
If necessary, round your answer to the nearest hundredth.

8, 6, 6, 18, 17, 11

The mean is the average, of all the scores divided by the number of scores

For this data set, the mean would be 11

You do this by calculating 6+8+6+18+17+11 divided by 6 (which is the number of scores)

This gives you an answer of 11.
