Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
3/4 + 7/16 = 12/16 + 7/16 = 19/16 or 13/16
13 + 12 - 6 - 2 (16 plus 12 minus 6 minus 2) (13 + 12 = 25. 25 - 6 = 19. 19 - 2 = 17!
13 + 35 + 48 = 96 As there are 3 numbers then 96 / 3 = 32 Check: 32 - 13 = 19 35 - 32 = 3 48 - 32 = 16 Then 19 - 3 - 16 = 0 Q.E.D.
The average is 18.

10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
3/4 + 7/16 = 12/16 + 7/16 = 19/16 or 13/16
13 + 12 - 6 - 2 (16 plus 12 minus 6 minus 2) (13 + 12 = 25. 25 - 6 = 19. 19 - 2 = 17!
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
13 + 35 + 48 = 96 As there are 3 numbers then 96 / 3 = 32 Check: 32 - 13 = 19 35 - 32 = 3 48 - 32 = 16 Then 19 - 3 - 16 = 0 Q.E.D.
It is 16/19
