Understanding your result
These are descriptive results for the observations you entered, not proof of causation, significance or a particular population distribution.
Common mistakes
- Choosing a population denominator for a sample without intending that convention.
Check your calculation
- Try a small hand-checkable list; confirm the stated quartile/rank/denominator convention before comparing with another application.

How large is the sample standard deviation compared with the positive mean?
Compare sample standard deviation with the positive mean as a percentage.
Common uses
- Compare sample standard deviation with the positive mean as a percentage.
How it works
CV=100*sampleStandardDeviation/mean Lists accept commas, semicolons, spaces or line breaks as separators; use a dot for decimals. At most 10,000 observations are supported. Calculations use floating-point arithmetic; displayed numeric results have up to 12 significant digits.
Worked example
Enter Numbers: 1, 2, 3. The result is Percent: 50.
