9    	16    	8
17    16    	9
4    	6       	3
Put them in order: 3, 4, 6, 8, 9, 9, 16, 16, 17
Cut the list into quarters: first quartile is 5 ; median (middle) is 9, 3rd quartile is 16

jack1 · Answer

9 numbers there, so 5th number is the middle 
= 9 (as 4 numbers either side of the 9)

first quartile is 5, as there are 4 numbrs in that side, so middle of 4 and 6 is 5

3rd quartile is 16, as there are 4 numbers on that side, so middle of 16 and 16 is 16
