Today in Statistics, we investigated the following scenario:
I gave students about 20 minutes to tackle this question (along with another probability question) in groups. The following was a humorous exchange I overheard:
Guy: It might be 4 choices…
Girl: Uh… If you can eliminate 4 choices, then you’re not guessing!
Of course, the practical analogy is the SAT, on which students earn 1 point for each correct response, and lose 0.25 points for each incorrect response (while netting zero points for every question they skip).2
Based on the earlier exchange, I felt the need to emphasize:
Yeah, if you can eliminate 4 choices on an SAT question, then you should DEFINITELY answer the question.
