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.
Order them: 15 16 17 21 21 Find the middle one: 17 That 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

There are infinitely many sets. One possibility is {18, 18, 18, 18, 18, 18}. Another is {15, 16, 17, 19, 20, 21} or {-5000, -4999, -4998, 5034, 5036, 1,000,000,000,000,000}
First 15 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24 and 25. In order to find median for a set of numbers we have to arrange numbers in order: Since the the first 15 composite numbers are already in order so we need not to rearrange. Terms are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24 and 25. Median is the middle value. Since there are 15 terms then the middle term is the 8th term which in this case is 15. So, the median is 15.
Mean = 21.6 Median = 19.5 Mode = 20 and 21 ------------------------------------------------------------------------ If the "2 1" (between 18 and 20 at the end) is supposed to be "21" then Mean = 26 Median = 20 Mode = 20
