In the example provided, the quartiles are: 25% = 16.5 (the median of {15, 16, 17, 18}) 50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22}) 75% = 20.5 (the median of (19, 20, 21, 22})
16.5 is the median.
It is 18, the middle number when they are in order.

16.5 is the median.
the median for 16,16,16,16,16,16,16,16,17,17,17,17,17,17,18,18,18,20,21,25 is 17
It is 18, the middle number when they are in order.

It is 18, the number in the middle when they are arranged in order.
I believe it is 19.5.
