<p>217 and 2290</p>
<p>Papa, We’ve got to be getting close to those 100 data sets. I’m very interested in seeing the stats you manage to come up with.</p>
<p>GD-- yes, just did a count & we probably have a few over 100 right now. I’m swamped with work at the moment & kids this weekend, and can’t get started until perhaps Sunday night. But with the 6/20 release of the June SAT results, since I can’t get started slicing & dicing until Sunday night anyway, I thought I would give it a few more days for, hopefully, a significant amount of new data sets to be posted. Another 10%-20% of data should improve the analysis. Sorry for the delay…PC</p>
<p>if any of u took stat… you cant get stats cuz its not an srs</p>
<p>1350 Psat, 1450 Sat</p>
<p>so papachicken when are you going to make another chart? (or have you)? since my message.</p>
<p>tryingnottocare… either way, even with voluntary bias, with a large enough sample size, it will form a normal distribution which can be analyzed… besides we’re comparing cc kids with cc…</p>
<p>Yeah, I hate myself every time I take these things… 212 2160; but I am upset that I made such stupid math errors. I gridded (by the way, College Board error, “grid” is not a verb) 25 instead of 250 on the PSAT, so I lost 4 points there, and I don’t even know what happened on the SAT, but I got a 720 on the math there… I think I screwed up filling in their idiotic bubbles… I should really work on that… Because it has happened so many times…</p>
<p>2130 vs. 225</p>
<p>212–>2180</p>
<p>OK, here’s a first installment…just the data & means. N=114, but I’ve excluded 2 data sets pending clarification by authors.</p>
<p>Here are the data sorted by PSAT.</p>

<p>207 / 2155 / 84 MEAN</p>
<p>The addition of 54 data sets from the prior summary of N=60 drove the average PSAT & SAT scores down 4 points & 32 points respectively, but the spread increased by 8 SAT points (mean variance @ n=60 was 76, now @ n=114 mean variance is 84.)</p>
<p>Also note the high reported positive variances at the lower end of the PSAT scale. I suspect there is some selective reporting bias here, as although such gains are certainly conceivable, few other more moderate variances are reported for the same PSAT range. </p>
<p>All for now. I’ll continue either late this weekend, or mid week after more data sets are reported. First chore will be to add new data then create a new, crude graph, followed by more detailed stats analysis.</p>
<p>i dont think u want to use the word “variance” to describe the difference…</p>
<p>I am the 189 / 2060 person, I did hand scoriung and my score became a 2080!!! (So now I am 189 / 2080)</p>
<p>219 / 2000</p>
<p>2280 v. 229</p>
<p>I’m still upset about my math…I swear there was only one question which I was unsure about, yet I had like 7 wrong on the math section.</p>
<p>How often are errors found with hand scoring?</p>
<p>191 vs. 2090 </p>
<p>This forum is crazy…An average of 2150!!! Wowzers. Some people just improve like crazy… 500 POINTS? I thought my 180 point difference was pretty drastic, but I guess I was wrong.</p>
<p>I’m the 179 / 1990 person… but I improved to 2030 (in one sitting) and 2070 (highest per section).
So I guess 179/2070… improved by 280 points.</p>
<p>BIG DIFFERENCE: 2300 vs 200</p>
<p>approximately 161 vs 213</p>
