<p>I've heard from nearly everyone that it is a joke.</p>

<p>But I'm getting B+/A- on AP Stats in school.</p>

<p>I mean I'm not that bad at math in general (800 IC/IIC).</p>

<p>I was plannning on just briefly reviewing it a week before the exam.</p>

<p>And now I'm a bit worried.. and just bought Barron's.</p>

<p>Should I thorougly go over the Barron's? or is it too much? (Especially because it's Barron's. I definitely wasted my time using it for IIC. It contained way too hard and unneccessary info than needed).</p>

<p>I don't have much time to focus too much on AP Stats because of other tests.. arrrgh help me~</p>

<p>AP Stats isnt a joke in my school, though everyone in the class got over a 4 in our practice tests. </p>

<p>I find AP Calc AB easier that stats, however. Strange.</p>

<p>AP stats is a joke. My hon class covered everything in the curriculum already, and we moved slowly. Now we are moving onto geometric statistics and its so much better. Currently we are doing the product of rolling 3 dice of the factors of 12, and what their expected probabilities are using binomials and trinomials.</p>

<p>if you can get 800's on sat ii math, then stats should be easy as (insert desert here)</p>

5

<p>It isn't easy....trust me. The class is hard here, the test is easy.</p>

<p>My son has a terrible Stat teacher and he is convinced he can't get over a 2 on the AP test. Is it possible to do some medium amount of self study and do OK on the test? He swears he hasn't learned anything.</p>

<p>Stat can be a great class. The math for stat is easy -- essentially basic algebra -- but knowing how and when to apply the concepts and formulas is what can be tricky.</p>

<p>Son took Stats last year and the class used Barron's and old CB tests from the website. </p>

<p>fwiw: last year, CB threw out something new on the exam (FR question), and many cc kids reported that they had to resort to rambling on the FR section for partial credit. However, I believe you can miss a whole FR and still earn a 5, as long as the others FR's are solid, and you ace the multiple choice.</p>

<p>My friend who scored a 36 on his ACT and 800's on both maths has a C in our stats class... Pretty sure the rest of the class is right there with him.. It is not slack at our school.. the test might be another thing, but def not a joke like we all thought going into it.</p>

9

<p>Same thing here....except I don't have a 36, etc...but the intensity is high.</p>

<p>The test, I hear, is okay. Our class, however, is the epitome of suckiness. It's not that the teacher is a bad person, it's just that her grading system is so messed up that what grade you get is almost no reflection of how much you know.</p>

<p>On the last test, the valedictorian in our school (of over 700 students) got 15.75/20. I (and I'm fairly hardcore in math/sci) got a 14, and my friend (Yale bound, by the way) got a 9.5. HOLY CRAP.</p>

11

<p>Yeah the class SUCKS here, val here, and I currently have a B avg . . ffffff that . . i hate the class, epitome of BORING</p>

<p>lots of people aren't doing so hot, grading is point scale which just screws everyone over . .</p>

12

<p>Well I'm sure my class would be the worst, though I did kind of enjoy teaching myself the entire curriculum in one and a half months.</p>

13

<p>I'm also a little surprised that only about 10% of people who take the test get a 5 on it. According to the scale, getting in the 68-100 range shouldn't be that hard.</p>

</p>

<p>Dumb people take Statistics. It's also why AP Calculus AB is a "harder" test than BC: Statistics is typically a senior-year course for people who felt that they wouldn't do well in Calculus.</p>

15

<p>Yeah, now I feel pretty dumb for only getting 30/40 on the practice MC part.</p>

16

<p>Can anyone explain to be what the power of test is?</p>

17

<p>Power is the ability of the test to reject a false null hypothesis. In general, tests with a higher alpha value have more power, but are also more likely to have a Type I error because you are rejecting more hypothesises. To put it simply, if you reject more (higher alpha), you will reject both bad ones (More power), and good ones (true null hypothesises (Type I error))</p>

<p>In our school, Stats is the math course for the humanities kids. The teacher is tough, so, as a result, the grades are low. However, I think that everyone in our class will at least scrape a 3.</p>

18

<p>Do you need to know how to calculate beta for the ap test?</p>

19

<p>So on the t-chart, the a (alpha) shows what?</p>

20

<p>you use an alpha value of .05 or .01</p>

<p>If the pvalue is smaller then if means that the test is insignificant, and that the null hypothesis is probably different than the alternative hypothesis.</p>

<p>(or is it the same...I forget)</p>
