10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
15, 15, 20, 24, 25, 25, 30 Mode: 22 Median: 24
Yes. In the set (10, 15, 20, 20, 25, 30) the mean, median and mode are all 20.

Sorted sample : 10, 12, 15, 16, 20, 20, 25, 80 Since there is significant mass near 10 (at 12) I would not exclude 10 as an outlier. Similarly there is significance mass just below 25 at 20, and I would not exclude 25 either. However, 80 is quite distant from the median at 18 and might be an outlier. In contrast, 18-10=8 and 25-18=7; these sample items are comparably close to the median.

Median is Exactly found Middle set of the Value. To Computing Median is to list all Scores in Numerical Order 12, 15, 24, 10, 25 ( it will be Decreasing order) 10, 12, 15, 24, 25
24 is the median. There is no mode as both 25 and 15 appear the most amount of times. 15 is the range, as it is the difference between the highest and lowest values, which are 15 and 30

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.
