Anyone else do some practice FRQ on collegeboard and find that scoring the frq is harder than actually doing it? The scoring guidelines are literally twice as long as the actual answers. I gave up on figuring out if I got E, P, or I…
@AnniiT you just define the difference (mu of d) in context
@MrWiggles
I know. As long as you get the right answer and show work, you will get E
@APmaster007 @MrWiggles I personally think the scoring guidelines for stats is ridiculously picky. I’ve been looking at the student responses on the collegeboard website and these poor kids are getting dropped points for wrong words and other tiny mistakes
This thread is kind of quiet haha. Anyways, good luck to all of you tomorrow!
I find it hard to believe that the graders actually go through each and every little thing in the scoring guidelines… I feel like they would just follow what @APmaster007 said. Otherwise it would take them so long to grade each free response.
The FRQs aren’t hard, it’s just there is a lot of writing, especially when they ask you to perform significance and confidence interval tests. I’m just hoping the type of test is obvious so at least you start off right.
What are the must know things to know for the frq’s to at least get partials on each frq lol? I’m only aiming for a 3 on the test.
@instanteco well you must definitely know how to interpret and perform significance test and confidence interval, interpret slope for linear regression, analyze data, and perform proportion tests and sample means tests (you must also memorize the test statistic formulas for z and t values).
I am cramming at the last second here, and I don’t get how to interpret slope for linear regression. If you use the YMS book, it’s the last chapter. Can you explain the essential ideas to me please??
@xyx5182 to interpret slope for linear regression t test, use this template: since my p value of ___ is less than alpha equals ____ (if they don’t say it, use 0.05), I ____ (reject/fail to reject) ho (null hypothesis). I (do/don’t) have sufficient evidence to conclude that ____ (your parameter which is beta) is ___ Ha (alternative hypothesis).
Thank you!
Are conditions really that important? I suck at making up conditions. Also, I heard that, when performing a t-test, you had to construct a LSRL graph in order to find out whether or not it was normally distributed. Do I have to do that? If so, how? Is it in the Princeton Review Book?
@ObitoSigma You need to draw a graph sometimes a box plot only when you are given actual data points
So in a two-sample t-test, would my X and Y be my two samples? Do I need to graph an accurate line using LSRL? Do I also have to do it for a paired-t-test or one-sample t-test? What should infer about it?
For example, if I decided to draw a boxplot, should I write underneath “The data appears normally distribution for ___.”?
The test is 3 hours away, I should probably start getting my butt to school.
“school” lol no way…I’m staying home to cram.
can anybody say if the barron’s book test is harder than the actual one? i passed the barron’s one but am not sure if i should feel safe or not…
@hackroberto Yes, the barrons book is harder. From what I have heard from other people who have taken the test in the past, the AP STATISTICS EXAM is relatively easy. Its easy to get a 4-5. You only have get a 50 percent for a 4 and a 65 percent for a 5.
GUYS THE TEST IS IN 4 HOURS SOSOSOOSOSOSOOSOS
