formulas for classic hypothesis tests

This repository contains a reference sheet hypothesis-tests-reference.pdf, which lists formulas you need to know for some classical hypothesis tests, and intro-to-hypothesis-testing.pdf, some lecture notes that I use when introducing students to testing for the first time.

The reference sheet is a work in progress. Here's the section on one sample tests:

For two samples tests we currently have:

The reference sheet is mostly for my students to use, as the courses I TA don't require a textbook and they spend way too much time looking for these formulas.

Pull requests to add new tests or improve notation and formating are very welcome! Both pdf documents are compiled from the corresponding *.Rmd files.

Caveat

Blasting students with this information is my least favorite way to teach hypothesis testing. If I had my way I would teach only the nonparametric bootstrap, or barring that, I'd follow Jonas Lindeløv's tests as linear models approach.
