P-Value Calculators for Normal, χ², t and F Distributions

These are the calculators I wrote for Stat 200 at the University of Illinois at Urbana-Champaign.

The p-value calculators are written in JavaScript and are embedded in four html pages (links are at the top of this page). The numerical method is explained in this documentation.
