PS  - Chauvenet's criterion only applies in polls to known value medians. it works best in physical contexts. Still, you might want to look into it, its a generally good way to find out exactly how badly you effed things up.

Oh, and of course - please understand. I'm not saying I don't eff things up. We all do. But right now, I haven't seen anything out of this polling project that looks like anything else other than a fox news version. Those guys are complete idiots. You really have tofind the real beat of the American heart, to be a good pollster. And it is a strong one. Good luck!
