Hope this helps! (:
First arrange numbers
14,15,15,17,19,20,21,23,24
19 is median
15+15/2=15 is first quartile
It is best to use mental math with some equations (5x5 or something that is easy enough that work does not have to be shown 10 dived by 5
3 + 8 + 10 + 12 + 15 = 48
48 / 5 = 9.6 or 10
3 - 7
8 - 2
10 - 0
12 - 2
15 - 5
7 + 2 + 0 + 2 + 5 = 16
16 / 5 = 3.2 or 3
The Mean Absolute Deviation is approximately 3
