Today we'll finish the Sexual Assault example that we started in Lab 05 last class and then start talking about A/B testing (also called permutation testing or two-sample testing). Next class we'll finish our discussion of A/B testing and then have Quiz 03. To prepare for Quiz 03, you should be able to run and interpret hypothesis tests so look over Lab 05 and material in the lecture notes for Days 22, 23 and 24 (today).
