AP Stat: Important Formulas

Test Preparation AP Mathematics & Computer Science

<p>Hey guys,</p>

<p>I'm in the midst of studying for Stats, and it occurred to me that there is no useful list of formulas that we need to memorize. CollegeBoard releases a formula sheet on the exams, and these are available online, but many of the more important ones are omitted. I'm specifically talking about test statistic formulas. </p>

<p>So, I figure, why not make a definitive list of things needed to memorize for the AP exam! </p>

<p>Cheers!</p>

<p>They don’t give you the rules for geometric probability (but I guess it’s assumed that you could reason those out?)</p>

<p>probability of failures until 1st success: p(1-p)^k
prob. that kth trial will be 1st success: p(1-p)^(k-1)</p>

<p>Alright, let’s make a list, starting with your stuff! I feel like I’m doing good unto all AP Stats students current and future. lol</p>

<p>Probability of failures until 1st success: p(1-p)^k
Prob. that kth trial will be 1st success: p(1-p)^(k-1)</p>

<p>This is a review sheet with formulas in it!

<p>Well, the geometric distribution is rather easily done in the calculator, so that’s more likely the reason why they didnt put it on there?</p>
