Calculate mean, median, quartiles and both population and sample standard deviations with pinned simple-statistics source.

Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
For 1, 2, 3, 4: mean and median are 2.5; Q1 is 1.75, Q3 is 3.25; population deviation is √1.25 and sample deviation is √(5/3).
Use the sample button to load the stated inputs, then change one option to compare results.
Method
All statistics call the actual pinned simple-statistics exports. Mean uses compensated summation; population variance divides squared deviations by n, sample variance by n−1. Missing-marker handling is explicit and skipped markers are counted; numeric tokens are not silently discarded.
The fixed-source README and complete third-party license notices are available through the source and notices links.
Limits
Finite values only, magnitude ≤1e100; up to 1.5 million characters. Different packages use different quartile conventions. Descriptive statistics do not establish normality, causation, or representativeness. Six-second Worker deadline; floating-point rounding remains possible.
