Chi Squared test calculator in JavaScript

Today a 9th grade student asked me if there was something he could do to tell if two categorical variables had a relationship or not. The Χ2 test would be perfect, except that most of my 9th grade students don't yet have the mathematical acumen to do the calculation themselves.

So I created a very simple calculator in JavaScript for the Χ2 test. It is located here: http://davidwees.com/javascript/chisquaredtest/.

Note that this calculator doesn't check that the original data is fit to be included, and definitely does not yet include the Yates correction for continuity.
