16.5 is the median.

It is 18, the middle number when they are in order.

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})

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

It is 18, the number in the middle when they are arranged in order.

min= 12 max=21 median=17 mode=17 mean=191

15, 16, 21, 23, 25

I believe it is 19.5.

The mean is 21 and 1/3 The median is 22 The mode is 24

17 There is an even amount of numbers, so you take the two in the middle and average them. Therefore, 17+17= 34/2= 17

(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)

25.5 is the median.

21. You put them in numerical order and then find the center one.

8 is the median of that group of numbers.

The median of these numbers is 5.

40.828

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.

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

Put them in numerical order and ther median is the one in the middle Answer: 20
