Teacher of elem gifted kids looking for resources


I teach math and science to gifted 5th and 6th graders. We recently read "Scammed by Statistics" by Ed Zaccaro (what a great book!) where my students learned a LOT about different ways that people misuse statistical information.

I am looking for origianl examples of bad graphs, inaccurate data, data collected through poor sampling practices, etc that my students could analyze themselves to identify the error found there. I can find a lot of places on line where this has already been done (with things like graphs on Fox News or in USA Today), but I don't want things that already have the analysis included.

Does anyone out there have some ideas about where I could find some resources like this for my students?

Thanks for your help!
