16+17+21+15+139=208
Order them: 15 16 17 21 21 Find the middle one: 17 That is the median
16
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})
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)

40.828
It is 18, the middle number when they are in order.
21, 22 & 23 15, 16, 17 & 18
To find the median of the numbers 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21, first, arrange them in order (they are already sorted). Since there are 10 numbers (an even count), the median is the average of the two middle numbers, which are 16 and 17. The median is therefore (16 + 17) / 2 = 16.5.
16.5 is the median.

16, 12+15+21 = 48/3 = 16
