Descriptive statistics
Summarize count, total, mean, median, range, population and sample variance.
Enter numbers separated by commas, spaces or semicolons. The tool sorts the values to find the median and range, then calculates squared deviations from the mean for both population and sample variance.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
Numbers (comma or space separated): 1,2,3,4,5
Example result

"mean": 3,
"median": 3,
"min": 1,
"max": 5,
"range": 4,
"populationVariance": 2,
"sampleVariance": 2.5
}Limitations and details
Use 1–10000 finite numbers; sample variance is null for one observation, and the tool does not infer a sampling design.
