mean variance is 75, that is SAT score is on average 75 points better than PSAT score (after PSAT is adjusted by one order of magnitude)
3:1 improvers to “de-provers”; 33 with SAT scores higher than PSAT, 11 with SAT scores lower than PSAT, and 3 status quo.
much more improvement potential at the lower end of the reported PSATs; for instance, reported scores with PSAT <200 averaged 175 point SAT improvement
more potiential to regress on SATs with higher starting PSATs; for instance, reported scores with PSAT >225 averaged 21 point decrease (2400 scale) on the SAT</p>
<p>A scatter plot says it all, but unfortunately can’t copy one in.</p>
<p>I know that SATs are not the most important thing, but I still wanted to decently. I got a 196 on the PSAT and a 2090 on the SAT. I guess this is not terrible, but it is certainly not where i wanted to be after the practice that i did. Everyone here did rather well, so can anyone give me some study tips? Thanks</p>
<p>hello32 - honestly, I have no idea how I got a 2390. However, between the PSAT and SAT, I did take a practice test each week, which def. helped just in learning the test. Good luck!</p>
<p>Each tick mark is 10 SAT points;
PSAT on Y axis, lowest on top;
Variance to SAT score marked by an “x”, negative on left side of PSAT “axis” and positive on right side of axis;
Accent (`) marks used to scale;
Did not mark 3 data sets where PSAT*10=SAT (Status quo)
<p>This helps me visualize the proportion of positive versus negative variances, as well as their position on the PSAT scale, i.e., high variances in the 175 to 200 PSAT range.</p>
<p>2190 vs. 220
and whats worse is that my math/verbal combined this time was only 1420 (AAHH!!) when I took the old sat I on the last time it was offered i got a 1490
i TOTALLY deproved
only writing went up by 10 points</p>
<p>At the risk of over-analysis, here are some other conclusions regarding the GROUP of data (n=first 47 reported).</p>
<p>In plotting the variances, one can observe a discernably larger positive variance at the lower PSAT values than the higher PSAT values. Fitting a least-squared line to the variances between 190 and 240 shows a 5 to 6 point drop in variance for every PSAT point, meaning for the GROUP of data overall, one can expect SAT score improvements to drop 50 to 60 points for every increase of 10 PSAT points within the 190-240 PSAT range. The fit is not so great statistically, but nevertheless, a trend is apparent. Other take-aways from the fit line: the GROUP showed a positive variance of 200 SAT points at 190 on the PSAT, a negative variance of about 75 SAT points at 240 on the PSAT, and no variance (i.e., the fit line crossed 0 variance) between 225 and 230 PSAT.</p>
<p>This mearly substantiates the age-old CC point (and an obvious one) that there is more potential to improve from PSAT scores when starting lower. What I find also interesting is that there is substantial potential for “de-provement”, especially with PSAT scores greater than 225.</p>
<p>When looking at the INDIVIDUAL scatter, no simple GROUP statistics like these can predict INDIVIDUAL correlations between PSAT and SAT. That is, many plotted variance points are considerably distant from the fit line. Undoubtedly, other factors not represented in the GROUP analysis are at play, such as pre-test practice, condition the day of the test, variations in each test, and many more also noted throughout CC. The hard lesson here is that there is “de-provement” potential starting from any PSAT score, but there is also plenty of potential to improve on lower scores or to hold good ones.</p>
<p>Yea, jq722, if he/she is willing to do this (inpart for you as well), just let him do it… its helping people understand things that could be confusing to them about their future. </p>
<p>And I would like to think that I have a life… </p>
<ul>
<li>patterns still hold, with ~+75 points on average added from PSAT to SAT.</li>
<li>for those that lost points from PSAT to SAT, average drop was 60 points.</li>
<li>for those that increased points from PSAT to SAT, avg increase was ~135.</li>
<li>one other note: these scores are obviously biased very high (i.e., PSAT & SAT scores are in the top few percentiles), hence, one should be leary of extrapolating to lower ranges.</li>
