AP Statistics Question

<p>So for the AP Stat. exam, do you have to know how to derive all the standard deviation, mean, binomial probabilities, ect. equations? I always just use my calculator. I hope I do not have to explain the significance or the actual formulas for these things!</p>

<p>Also, what are the top things I should study besides the inference tests...</p>

<p>I would know linear regression, the law of large numbers, what inference tests to use when (Z & T), and just want all the equations are, and when to use them. Also, know how to interpret everything you've learned. Know what the standard deviation IS (sounds easy, but a lot of people really don't). Binomial v. Geometric, conditional prob, and how to use your calculator. </p>

<p>But, yeah, I basically plugged everything into my calc.</p>

<p>In addition, know the different types of errors (Type I and II) and know the basics for calculating the probability of each and what influences power.</p>

<p>lol basically if you can use your calculator well your good</p>

<p>You won't be asked to explain any of the equations, e.g. why is this the formula for standard deviation, why is degrees of freedom for this t-test n-1 and for that one n-2?</p>
