<p>everyone in my school is using this "Put this in your profile if you got ****ed by AP Stats.. "</p>
<p>Was #6c Chi Square Goodness of Fit?</p>
<p>Most of it. It's also partially ANOVA/Variance.</p>
<p>Oh never learned that.</p>
<p>What was the purpose of using what we got in (b)
for part (c)?</p>
<p>I don't think I used it when I tested.</p>
<p>i do not believe that number 6 was part of the course, bcus our teacher did not teach us the last chapter which had something with anova</p>
<p>wassnt a and b for 6 staightfoward?</p>
<p>wassnt a and b for 6 NOT staightfoward?</p>
<p>ok a was completely straightforward...b on the otherhand took me like 30 minutes</p>
<p>I thought our stat book was better than the barrons book.
Our book explicitly and clearly states assumptions, conditions, etc. so it's actually easier to use that when studying.
Barron's doesn't do a great job of that-I had a hard time finding key things like that.</p>
<h1>6 was incredibly easy. All you had to do was <em>can i talk about this yet? lol...if i can i'll edit my post</em></h1>
<p>but there was barely any math involved</p>
<p>at first it's kinda *** but after you know what you're doing...you realize how easy and retarded it is. I didn't think the test as a whole was THAT bad. XD watch me get a 1. meh if so many people thought it was hard...i think i easily got a 4/5</p>
<p>i didnt read whole thread, but did anyone simplify that whole thing in no. 6, i believe it factored out to something nice if u use formula sheet?
:-) or :-( ?</p>
<p>technically it was nice to start out with...you just dont really see it that way. you just put the data into your calculator to find the standard deviation and plug that into s...nothing to it really</p>
<p>i used the formula sheet and ended up with the sum of the squared residuals of z over some value ( i dont know if im allowed to be specific). The rest was easy sailing. But i must say, i was flabbergasted by that expression (almost said an expletive but proctor was near), it just scared the wits out of me.</p>
<p>Hey, I am a student who took the stats test in south korea
but my number 6 seems differnet from yours. ALthough ours was as outrageous, it didnt involve things like S, SE and Chi quiares you guys are talking about....WHY IS THIS SO??</p>
<p>Boomer125!!!</p>
<p>i simplified it to the exact thing u got!!!!</p>
<p>sum of squared deviations from mean divided by sigma2</p>
<p>do u remember the value u got?? hopefully its right!!!</p>
<p>does someone remember what each FRQ was about...i forgot the order:</p>
<p>1) Catapults
2)
3)
4)
5)
6) Thermostats</p>
<p>i know tiger shrimp and M = D + E was in there</p>
<p>hey does ne one know how you would mark the histograms for the thermostat question? I was totally clueless and how would u go from that and find which one would have the most variance? That was extremely gay i was ****ed</p>
<p>yeah i had no idea on that either!!! i just had like 5 mins left so i randomly marked each histogram and then just wrote something for variance lol</p>
<p>coolphreak-
that's why I said I made up a number and moved on. I wasn't 100 percent about the math but I new what I had to say afterwards so I just mad ethe grader follow my logic.</p>
<p>M=D+E Was #3. I messed that one up. You had to do probability, and I had no clue there.</p>
