<p>I always hear people saying it's the easiest exam.. blahblah. But I'm kind of worried... the practice FR's are pretty hard to me. Anyone want to form a study group, even if there's only 2 days left? We can share info and stuff.</p>
<p>Also, I heard that knowing how to use the TI-83 is important. Do you know any prep books that lists the important functions of TI-83? (I have Barrons and Princeton)</p>
<p>Barron's has it in the back of the book. Quick summaries at least. There's some book out there that I saw that just has all of the calculator functions. I'll try to find it.</p>
<p>Yeah, I'm also worried.</p>
<p>I'm freaking out.</p>
<p>Stats = the bane of my existence. I feel like it never seems to get easier, and my teacher just finished everything, and now I have about one week to review. just crossing my fingers for a 3, at least. </p>
<p>anyone else getting the different types of confidence intervals and significance tests mixed up?</p>
<p>lol, the bane of your existence? Keep reviewing, I’m sure you can at least pull a 3. I can understand where you may confuse those two, but the confidence intervals and significance tests aren’t that difficult because they all follow the same basic procedure. State parameter of interest, hypotheses (for tests), check conditions, calculations, reject or fail to reject (for tests), conclusion in context. Plus, they are very generous with what they give out on the formula sheets. All of the standard deviation formulas are given, and the basic formula for an interval and test is given. It is just a matter of recognizing which one to use and then putting it all together. I would recommend going back to old FRQs and trying them out, then looking at the scoring guidelines. I tried doing this and now I consistently score 4s on them. Also, if you haven’t already, get a review book and study it. I know the popular claim is to use Barron’s, but I have actually found REA to be the best for Stat, IMO. I have Barron’s also, and it’s questions are more difficult, so they do prepare you well. That’s my input anyway. So just take this post for what it is worth and good luck on the exam.</p>
<p>I’ve been using princeton, and it’s helped me quite a bit on the probability section. It’s just that with confidence intervals and significance tests I often end up mixing conditions and formulas. And i’ll definitely try to get some old FRQ’s to practice. thanks for the feedback. :D</p>
<p>Yup, PR is the way to go for most APs. I found that the practice tests were a little too easy though. The review is definitely helpful though, especially that probability section.</p>
