In statistics, the chi-square test calculates how well a series of
numbers fits a distribution. In this module, we only test for
whether results fit an even distribution. It doesn't simply say
"yes" or "no". Instead, it gives you a confidence interval, which
sets upper and lower bounds on the likelihood that the variation
in your data is due to chance.
