<p>I’ll take a shot at it.</p>
<p>Putting all the data into pairs of AP and SAT scores (not distinguishing between subjects), the [correlation</a> coefficient](<a href=“http://en.wikipedia.org/wiki/Pearson_correlation]correlation”>Pearson correlation coefficient - Wikipedia) is 0.39, which makes this a medium-strength correlation (according to the guidelines on that page). Thus, you can somewhat predict the student’s AP score from his or her SAT score (and vice versa).</p>
<p>Taking a look at the data some more, it appears that almost everyone with a 750 or above on the subject test gets a 5 on the AP test. Out of 81 people who got a 750 or above, only four got a score below 5 on the AP, all 4s. (The AP exams were Physics B, Chem, US History, and World History; the only 800/4 combo was on Physics B.) </p>
<p>Here are the means for the SAT scores corresponding to each score on the AP test (rounded to the nearest possible score):</p>
<p>1, 2 - no data
3 (6 pairs) - 680
4 (14 pairs) - 710
5 (102 pairs) - 760</p>
<p>And we do the same for ranges of SAT scores (rounding to the nearest tenth):</p>
<p>490 and below - no data
500-690 (18 pairs): 4.4
700-750 (28 pairs): 4.6
760-790 (37 pairs): 4.9
800 (39 pairs): 5.0</p>
<p>As most people would expect, it appears that a higher score on one test generally predicts a higher score on the other.</p>
<p>Of course, most people (84% in this sample) get 5s here on CC, which is not true of AP exams in general. (In fact, the lowest SAT score in this data, 500, yielded a 5 on the corresponding AP exam.) So it’s kind of difficult to figure out whether we can actually predict much from an AP score.</p>
<p>Here are scores for myself and some people I know:</p>
<p>Biology 5/800
Biology 5/680
Physics B 5/800
Physics B 5/760
US History 5/790
US History 5/780
World History 5/800
World History 5/790
Literature 5/740 (SAT II taken junior year, AP taken senior year, so I don’t know if this should count because the test was taken before the AP class)</p>
<p>I know there are already too many 5’s to predict much. I really don’t know of anyone who’s taken an SAT II and not gotten a 5 on the equivalent AP exam. People at my school only take SAT II’s because they’re applying to top schools and need them, so high scores tend to be pretty uniform.</p>
<p>Sorry, but what is SAT II?</p>
<p>SAT II = SAT Subject Test</p>
<p>They were called the SAT IIs until 2005, but people still use the name because typing out “Subject Test” is a pain in the butt.</p>
<p>I made a little typo earlier:</p>
<p>Physics: 4/560</p>
<p>HUGE improvement from last year. A little note: make sure you write small on the AP test!</p>
<p>Physic B 5
SAT2 Physics 800</p>
<p>APUSH 5
SAT2 USH 780</p>
<p>500-690 is a pretty generous range.</p>
<p>680 USH, 3 AP test for me. Possible re-score.</p>
<p>740 Bio-M, 5 on AP
700 US History, 5 on AP (I’m really good at the writing component on the AP exam (especially DBQ), so this may explain the combo)</p>
<p>US History:
SAT II - 770
AP - 5</p>
<p>Math:
Math II - 760
Calc AB - 5</p>
<p>Chem:
SAT II - 800

<p>Physics (B) - 800, 5</p>
<p>US History - 740, 5</p>
<p>Math II (Calc BC/AB sub) - 800, 5, 5</p>
<p>800 math 2c (improvement from 770 last year lol) - AP Calc BC and AB subscore 5
780 physics - AP Phys C Mech and E&M both 5 (i blame the physics B stuff which i tried to cram in two and a half weeks after all APs were done)
??0 chem - AP Chem 5 (gonna take SAT II next year)</p>
<p>Chinese:800, 5 (duh. Look at my location…)
