Rearrange the numbers in rank order from lowest to highest.
21,22,23,27,27,28,30,31,34,35,36.
There are eleven (11) terms. You find the absolute middle term , so that there are 5 terms to either side of the middle term.
In this case the median is '28'.

5, 5, 9, 12, 18, 22, 25The median is 12.
16 18 22 28 The median (middle number when numbers are in numerical order) is 20.
Median of 16 and 28 is (16+28)/2 = 22

The Median is 23.5.
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})

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