Hello, never2late, I got the workbook off of Amazon ( a website that sells used books in new condition.) You can purchase it as a set with the statistics for dummies and workbook or just by it's self. If I had to do it again, I would probably just buy the workbook.In my opinion, it explains things just as well as the actual text. The workbook has great examples and explanations for pretty much all the topics that you'll need. Couple that with IC and you're sure to pass! Best of luck!
