<p>I'm taking the AP Statistics test, and I'm a bit confused about how the Free Response Questions should go.</p>
<p>When you're doing a Free Response Question, are you supposed to know how to find something rather than using a calculator?</p>
<p>For example, I know how to find Margin of Error by hand, but I know that I can achieve the same results by just plugging it into the calculator. Can I just go straight to my TI-89, or do I have to write out ME = z* x SE(p) = z* x [sqt(pq/n)] ?</p>
<p>hey, we just did margin of error :]</p>
<p>no, write out all formulas/steps. my teacher also told us to write out ALL assumptions [normal distribution, srs, etc,]. basically, write out every single thing u know.</p>
<p>It’s always safest to write everything you can, of course.</p>
<p>Anyway, you don’t necessarily have to write out every single step on the AP test. But you definitely need to say what kind of analysis you are doing, and demonstrate that all the conditions required for that analysis hold.</p>
<p>Also, are they going to provide any formulas, or do we need to memorize every single thing we’re taught?</p>
<p>we’re given a formula sheet of the major ones. also, i plan on using my note-folio in my ti-89…i type lots of information on that, haha.</p>
<p>Our teacher told us that they wouldn’t give us any points at all if formulas were not listed. Like you can’t just write Normcdf(), you have to actually do a z-score and all of that. It’s rational, stats is learning how to CALCULATE, not how to use a calculator…
Best of Luck Mate!</p>
