<p>Q for those who have taken the exam before..</p>
<p>Are we expected to use the formulas that are given to us on the exam?
ie.
Correlation r = (1/n-1) (blah blah blah)</p>
<p>Can we just use the TI and give them the answer + the strength of the correlation?</p>
<p>do you want me to ask my ap stats teacher for you?
she goes and grades the exams
by the way, have you heard of CUSS, lots of people write it on their FRs as a memory thing, she told us about it. It includes the 4 main elements you need to look for when describing a distribution. </p>
<p>C - center
U - unusual (outliers and such)
S - spread
S - shape</p>
<p>Yes that would be great sarorah :)</p>
<p>I haven't heard of that acronym, but it looks pretty useful. Ill keep that in mind.. I'm selfstudying stats so I don't have resources to get those tips and tricks</p>
<p>thanks again</p>
<p>Haha I'd never heard of it as CUSS. I'm in AP Stats this year and we're always told to not forget our SOCS- Shape, Outliers, Center, Spread</p>
<p>How is the AP Stat exam organized? How many multipe choice etc. etc.</p>
<p>50 multiple choice, and 6 free response questions. </p>
<p>No, u don't need to memorize the formula for correlation, I didn't. I just did a stat plot and LinReg, and my calculator gave me R and R^2.</p>
<p>no problem, anytime
email sent, i'll probably get a response by Monday</p>
<p>this class is interesting at my school. the teacher isn't there, so we watch the broadcasts and lots of assignments and stuff are posted online. everything has to be faxed back and forth. she teaches like 140 students from different schools, but she's a pretty good teacher. </p>
<p>lol heather, cuss is easier to remember in a high schooler's mind
pilebay i'm not sure exactly how many
but you get 90 mins for the multiple choice
and 90 minutes for the free response
and free response counts for 50%
and so does multiple choice
my teacher actually grades our tests like the actual ap exam, so the curve is pretty nice (you can make a 68 and still get a 5)</p>
<p>MC + FR Raw Score
68-100 (5)
53-67 (4)
40-52 (3)
29-39 (2)
0-28 (1)</p>
<p>Either use the formulas or write out what you enter in your calculator on the exam, both are acceptable.</p>
<p>And don't worry, the test is reeeaaallllyyy easy.</p>
<p>Wait I have to write out what I do on my calculator?</p>
<p>Like
"press [stat]"
"1.Edit..."
etc?</p>
<p>no, just like TInterval (etc.)</p>
<p>any practice problems ? ( not from CB)</p>
