FAQ

How do these tools calculate sample variance?

The tools use the standard statistical formula for sample variance, dividing the sum of squared deviations by the sample size minus one (n-1) to provide an unbiased estimate of population variance.

Is my statistical data kept private?

Yes. Text inputs are not stored on our servers, and any uploaded data files are automatically deleted after 6 hours. Processing occurs on our secure servers rather than locally in your browser.

Do I need to install any software to use these tools?

No, all tools are accessible directly through your web browser. You can perform complex statistical calculations without any local installation, as the processing is managed by Elysia Tools servers.
