    Does anyone have a good place to reference about using psychometrics for multiple choice? A non-psych teacher is attempting to use a test filled with error and appears unwilling to budge unless the wind flies up her skirt at the right angle.

    Thanks!

    I'm not sure i understand your question. Are alluding to examining the distribution of the scores obtained in the exam (ideally a "bell curve" in undergrad classes), and/or individual item analysis? Or are u referring to the reliability of the test....like internal consistency, split-half reliability, things of that nature? Or maybe you are referring to construct and/or convergent validity of the exam? How is this teachers test filled with "error" exactly? What is wrong with it?

    Nevermind. I figured out what I needed. I worded the post badly. Essentially an instructor wrote a very ambigious test and said even though 97% of the class got an item wrong that it was still a good question :confused:

    I was just looking for some data about how to do item analysis of mc tests to try to reason with her. (and the above was just a specific example which spread throughout a ton of the questions). The whole class is in a bit of a tizzy.

    I was looking for item discrimination index and such.

    thanks anyhow :thumbup:
