Hey, I just got back from taking the stats dsst. Scored a 65 with about a month of studying IC and the dummies workbook. (I'm horrible at math). First off, don't just use IC as your only resource. I'd recommend getting the idiots guide OR stats for dummies (the workbook). You absolutely will not understand null hypothesis without one of these two books, and trust me, you need to know it for this exam. At least 15 questions about null hypothesis alone on the test I took. Probabilities wasn't a big deal. The section under college math will definatelly be enough to prepare you for all the probability questions. Confidence intervals wasn't that prevalent in my test, but i've heard it was for others. Maybe 8-10 questions about it, but they were all relatively simple. Correlation and line regression were big on my test. Understand how to read scatterplots and how regressions and correlation play into them. Also, look up stem and leaf plots and box plots and understand how both work. 4 or 5 questions just on those two things which IC doesn't even mention. Chi square had a couple of questions, but wasn't too diffiucult. Even after a month of studying, I wanted to walk out of the test after the first 5 questions. The next 65 weren't bad, then they got tough again around the end for me. ALOT of easy questions, mixed in with a couple hard questions. All in all, a doable exam. On another note, definately get yourself a business calculator. I used the BAII plus, and it did ALL the calculations for me. Besides that, good luck!
