Most of the time, hubby and I listen to NPR while in the car. On Saturday morning, while running around town frantically because I was about to buy a new car *woot*, there was an interesting tidbit about polling and margin of error for confidence intervals. I saved it and plan to use it for my uni kiddos next week when we cover this topic. I thought some of you might find it useful as well

I posted this same link on the AP Stat Listserv and one of the other teachers had a blog about margin of error and common errors in opinion polls - I *love* the "urn" example!!
