<p>By that measure, we should have something like this-
median= (10.7+10.8)/2= 10.75
Now upper half-
1 6.6
2 8.2
3 8.8
4 9.5
5 10.7
Median=8.8</p>

<p>Lowe half-
6 10.8
7 10.9
8 13.2
9 13.3
10 14.3</p>

<p>Median= 13.2</p>

<p>So Q1=8.8 and Q2=13.2</p>

<p>If we include the first median in the list-</p>

<p>Lower half-
1 6.6
2 8.2
3 8.8
4 9.5
5 10.7
M 10.75</p>

<p>median=(8.8+7.5)/2= 7.15</p>

<p>And a similar incorrect result for the lower half…</p>

<p>So I guess I just didn’t get it!
HELP!</p>

<p>You DON’T count the entries that were part of the calculation for the media.</p>

<p>You use 1-4 and 7-10.</p>

<p>Your answers are still wrong though.</p>

<p>[Interquartile</a> range - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Interquartile_range]Interquartile”>Interquartile range - Wikipedia)</p>

143

<p>So basically the answers given are wrong?
I found the question/answer at [Exploratory</a> Data Analysis](<a href=“http://www.mrholloman.net/APS/Notes/Chapter01/apsnotes01.xht]Exploratory”>http://www.mrholloman.net/APS/Notes/Chapter01/apsnotes01.xht)</p>

<p>why dont you just plug in the values into a list and use 1 var stats to find everything?</p>

145

<p>I’m about to take this in 15 minutes lol. I’m so effed.
Good luck, everyone! :)</p>

146

<p>Didn’t get you eliminator.</p>

147

<p>MCs were much harder than those of barrons…
FRQs were okay I guess how did u guys think</p>

148

<p>To find the quartiles, enter the data into a list, press STAT, then CALC then 1 (which is 1 Var Stats). Scroll through the answers and they’ll reach it eventually.</p>

149

<p>i thought MC was kinda hard
yet FR was a breeze
easiest question in 6 in years.</p>

150

<p>MCs were okay.
FRs were okay as well, except for the second one :(.</p>

151

<p>mc’s were okay…the frq were okay…but i was pressed for time, so don’t know how good i did there…b/c our proctor said we could go whenever everyone finished…and i ended up being last, with 6 ppl. mad at me.:)…
how hard do you think the curve will be?</p>

152

<p>Idk about you guys, but I probably used a total of 2 equations from the formula sheet for my FR answers.</p>

153

<p>the MC was mad hard
FRQ…SUPER easy</p>

154

<p>I thought the whole thing was alright; FR was easy. Given the curve, I expect I’ll get around a 4 or so.</p>

155

<p>I self-studied for the exam! (I read 20 out of 27 chapters of the textbook and I attended the AP Stats class at my school for a month). And I thought I would be absolutely slaughtered because I really didn’t know too much about… basically any of the inference tests. But the exam seemed really very easy.</p>

<p>The ironic part: I was unable to do the first problem on the FRQ. Isn’t the first problem always supposed to be basically the easiest one on the FRQ?</p>

156

<p>The multiple choice were much harder than usual…but the FRQs were much easier than usual, so I guess it kind of balances out.</p>

157

<p>No actually. I’m assuming you could only not do the latter part of question 1. It wasn’t hard; it just was the second to last unit so you wouldn’t have known it by not having gone through the whole course.</p>

158

<p>yea i didnt think it was that hard
considering that i didnt study at all for it and didnt learn anything from class
i think i will probably get a 3
but i guess they never change the free response
cause they are always ask the same material</p>

159

<p>Can we discuss MC or is it not allowed?</p>

160

<p>wait, we can discuss FR?</p>
