Let's assume that a student has a multiple choice test, whereby each test only has two options. If the student doesn't know the answer and randomly guesses then his score will be 50%. If the student does know the answer his score will be 100%. So my question is, knowing the score from a 2 option test, how do we predict the score of an n options test? For example, a 50% score in a 2 option test should be the equivalent to a 1% score in a 100 option test, while a 100% score in a 2 option test would be the equivalent to a 100% score in a 100 option test. Thanks! Last edited by Apple30; May 17th, 2019 at 06:35 PM.
