There are a growing number of books for the IB options, and probably more than any for the Statistics Option. It seemed to me that the available options often over complicated the topics and, although the IB course is a calculator course, many of the techniques covered in other books stressed a non calculator and more traditional approach. For that reason I decided to produce material for the entire option and publish in the form of a printable electronic book. The book is currently only written for the TI83/84 family of calculators.
A full version of the book can be viewed here but is watermarked as unregistered and is not printable. (Trouble downloading?)
