How do you solve for a mean absolute deviation? can you explain it to me very well because i have no clue. all i know is that first you find the mean of all the numbers. that's it.

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean. For the first set: MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15 For the second set: MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6 Note that when you only have two data points the mean is directly between them, which is why the distances are the same.
