Mean, Median and Range Calculator
Calculate arithmetic mean, median, range, and item count from a comma-separated list of finite numeric observations.
Calculate mean, median, and range
How this tool works
Mean, median, and range summarize different properties of a numeric dataset. The tool parses comma-separated observations, sorts a copy for the median, and keeps the original values available for the arithmetic mean.
Mean is the sum divided by count. Median is the middle sorted value or average of two middle values. Range is maximum minus minimum.
How to use it
- Enter numeric observations separated by commas.
- Check that every intended value appears in the list.
- Review mean, median, range, and count together rather than relying on one statistic.
Worked examples
Odd-sized dataset
- Input
- 4, 8, 10, 12, 16
- Output
- Mean 10, median 10, range 12
The values sum to 50 across five observations. The sorted middle value is 10, and subtracting minimum four from maximum sixteen gives twelve.
Even-sized dataset
- Input
- 2, 4, 8, 10
- Output
- Mean 6, median 6, range 8
The sum is 24 and count is four. Median averages the two central sorted values, four and eight, while range is ten minus two.
Limitations
- The calculator does not identify outliers or determine statistical significance.
- Invalid non-numeric fragments are ignored, so review the entered list carefully.
