• I think everyone here who has taught statistics has had a student give an answer where a probability is not restricted to the interval $[0,1]$ but that's really more disconcerting than funny. – Macro Jun 18 '12 at 18:02
• @Macro Every...single....exam I had multiple students give probabilities less than 0 or greater than 1. It made me want to scream. This was not restricted to Intro Stats... even in Intro to MCMC I saw it. – Ryan Rosario Jun 18 '12 at 18:08
• The early answers to this thread are so off-topic I think this should be closed. SE is not the place for lists of jokes, etc. (even though we all enjoy them.) See guideline #3 at blog.stackoverflow.com/2010/01/stack-overflow-where-we-hate-fun, for example. I anticipate complaints, though, so I'm holding back. But if the quality doesn't go up quickly, I won't hesitate to put in a close vote! – whuber Jun 18 '12 at 18:35
• It's interesting how the off topic answers are getting voted up as well. – John Jun 18 '12 at 19:35
• I had a post that was off-topic so removed it. As far as true students' mistakes go: I am a grad student and have been teaching into to Econometrics for two semesters. I have seen: complete inability of students to work with fractions, things like: 1/2 + 1/3 = 2/5, answers with negative probability, negative variance. Students constantly mess up their orders of operations. I got blank stare when I asked a student "What is the probability of getting heads in a coin toss". – Akavall Jun 18 '12 at 22:40
