It is 20, the number in the middle when they are arranged in order.
10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
16.5 is the median.
The mean will increase from 14 to 20. The median will increase from 12 to 15.
Mean = (11 + 14 + 20)/3 = 45/3 = 15 Median = 14 Mode = 11, 14 and 20 (these values appear once, others do not appear even once!)
It is: 22.5
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
Median = 15
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
10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
12
16.5 is the median.
The mean will increase from 14 to 20. The median will increase from 12 to 15.
Mean = (11 + 14 + 20)/3 = 45/3 = 15 Median = 14 Mode = 11, 14 and 20 (these values appear once, others do not appear even once!)
It is: 22.5
Yes. In the set (10, 15, 20, 20, 25, 30) the mean, median and mode are all 20.
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.
The median is 20.
