Yesterday, I spent the period going over some mathematical formulas for baseball statistics for use in my Algebra II class today. I've arranged for them to have a statistical lesson via videoconferencing today. We discovered that the batting average formula is similar to a simple one step equations and can be solved the same way. The slugging formula is a bit more complex but similar to the formula for finding your GPA. I was able to introduce the students to statistical deviation which is a topic I don't usually get to so this is really pretty good.
appzest has a EZ statistics lite app which tests students on various topics of statistics. The lite version is free and has limited questions but has a data base of questions which can be used for students to test their knowledge. I am going to go looking for apps that might explain more about probability and stats over the summer.
