As I'm sure many people on this list are doing, I am trying to find materials to use in AP statistics next year. I am looking for some software. The Acorn book strongly encourages the use of computers in the class along with the graphing calculators. I've noticed that many of the textbooks make reference to Minitab. Is it substantially better than anything else that's out there? Does anyone have any experience with several statistical packages that would be willing to put their thoughts about them out here for the rest of us to see? Thanks in advance for any help you can offer.
