The median is 15.
(0, 2, 15, 16, 17) 0+2+15+16+17 = 50 50/5 = 10 The median is 15, the mean is 10.
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
Mean = 7.9 Median = 7 and 8 Mode = 4 and 12 Range = 2 to 15.
8! Because 8 would be in the middle of the numbers!

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
Mean = 7.9 Median = 7 and 8 Mode = 4 and 12 Range = 2 to 15.
8! Because 8 would be in the middle of the numbers!
Median = 15
13 - if there is no "middle" number then you take the average of the 2 either side of where the middle would have lain.
The answer is 8.5
10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
So first let's order the set: 4,8,12,12,15,16 The mode is 12, there are 2 of them and 1 of everything else. The median is also 12 and the mean is (4+8+12+12+15+16)/6
http://store.microsoft.com If you have a list with an even number of number in it, then your median will be half way. e.g. 10, 11, 15, 19 the median in half way between 11 and 15. To find this, we do 11 + 15 and get 26. Then we / by 2, to get 13. This is the median If your numbers are (for example) 10, 19, 28, 30 then the median is half way between 19 and 28. So, 19+28 = 47. 47/2 doesn't equal a whole number, but we still do it, to get 47/2 = 23.5. This is the median.
