SAT Percentages

<p>Hey guys, do any of you know where to find that chart that tells you how many people got a 2400, 2390, 2380, etc on the SAT?</p>

<p>Are there percentile ranks for the PSAT? I’ve been dying to find those, but I can’t seem to pull them up anywhere.</p>

4

<p>LoL, I thought they would be the same or close, but I’m 10 percentiles higher on my PSAT than on that chart for the SAT.</p>

<p>Kean, this is probably as close as you will get: <a href=“http://talk.collegeconfidential.com/sat-preparation/822539-silverturtles-approximations-psat-percentiles-sat-concordances.html[/url]”>http://talk.collegeconfidential.com/sat-preparation/822539-silverturtles-approximations-psat-percentiles-sat-concordances.html&lt;/a&gt;.&lt;/p&gt;

<p>I see. So a 2400 SAT is about 1 in 5000. A 240 PSAT is about 1 in 10000, according to your approximation. So it’s rarer to get a 240 on the PSAT than it is to get a perfect score on the SAT? Hmm.</p>

<p>Probably: people are generally less prepared and recognize that whereas higher is always better on the SAT, once they hit the cutoff for the PSAT, the actual score is moot. There are fewer questions on the PSAT, but the curve is generally stricter. In any case, your scores are respectable. :)</p>

<p>Here’s a simple math formula to get the percentile for any score on any test:</p>

<p>Get the mean and standard deviation of scores. Then, to find the percentile for any given score, subtract the mean score from the score you want to find the percentile for. Divide this difference by the standard deviation. Then look on the internet for a Z-score calculator, and enter the number you got when you divided. Multiply by 100, and that is the percentile.</p>

<p>I have never taken a statistics class; but doesn’t this method presume a normal distribution? (Such is not the case.) I would feel more comfortable in the College Board’s rough percentiles than in this.</p>

Indeed it would. While the SAT is roughly standard, it’s not standard enough to use z-scores accurately.</p>
