I added a calculation of chi-squared to Cats or Dogs. This gives it a certain statistical honesty at the expense of some of the fun (because most of the funny results the site generates are not statistically significant and you are now told that). Nevertheless, some of the results are still surprising.
The original post was in the category: cats_or_dogs but I'm still in the process of migrating categories over.
