FAQ

How do these p-value tools process my data?

When you use a tool, your input is sent from your browser to Elysia Tools servers for calculation. Text inputs are never stored, and any uploaded data files are automatically deleted after 6 hours.

Which statistical distributions are supported?

The collection includes tools for common distributions such as Normal (Z), Student's T, Chi-Square, and F-distributions, allowing you to find p-values for both one-tailed and two-tailed tests.

Do I need to install any software to calculate p-values?

No, all tools are accessible directly through your web browser. The processing happens on our backend servers, so you can perform statistical tests on any device without local installation.
