The mathematical mean is another word for an average. To find the mean, add up all the numbers and divide the sum by how many numbers there were to begin with. In this case, when you add the numbers the sum is 137. Divide that by 9 and you get 15.2 as the average.

mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42

One possible set is {9, 9, 10, 11, 12, 15, 18}

The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
If you mean NRL then there are 13. If you mean AFL [Australian] then there are 18. If you mean Rugby Union, then there are 15. If you mean association football [soccer], then there are 11. If you mean NFL [Grid iron], then there are 11. If you mean Canadian then there are 12. If you mean GAA [Irish], then there are 15. If you mean Grappleball football, then there are 10.
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
