I class today we did problem C-1. A nice regression problem. I also passed out the first part of the Super Six. You should how to do every step of the Super C-1 and then you will be able to every basic regression skill that the AP test will ask.

Someone asked if it is OK to "random residuals". I know that I've put that phrase on the board. On further reflection, it is not clear communication. Instead please say "the residual plot is random". It makes no sense to say a bunch of numbers are random.

I also passed back your regression test. You should fix all your mistakes.

Regression will be a big part of Thursday's Quest.
