<p>does anyone know the most common answer? I’ve always heard pick b or c but that was for 4 choice questions. My teacher tells us to pick a letter and fill in all the ones we left blank so I’m trying to figure out what is best</p>
<p>D, all day. Don’t listen to what the B and C peasants tell you.</p>
<p>I actually counted an old AP test and D won by far, I should probably be studying instead of counting answers but oh well</p>
<p>Well B won on my old AP test. Need more data 
Random tangent–based on a compilation of past AP tests for Chemistry, B is the most common answer by (I don’t know how much).</p>
<p>One thing i’m sure about is that it’s definitely not A. It is never A, like, for any AP test. Or E, but no one cares about E.</p>
<p>Yeah right. E was tied with B on the 2002 AP Statistics test. But you guys should do a chi-square test on the proportions, because I doubt there is a significant difference because even though there were only 4 C’s on the AP stats test (out of 40 questions) the probability that this occurs by random chance is greater than 25%… But what I can confirm for that stats test is you’re more likely to get the question right if you guess all the same answer as long as you don’t pick C which of course is a .2 chance that you actually do that.</p>
