Item difficulty

Postby vkrish » Wed Jun 08, 2016 6:02 pm


Can someone help me in telling me what the steps are to look at Item difficulty if there are 20 items in a test administered to 20 students? I can do this on excel easily - p= number of students who answered item correctly/number of students but not able to find how to do this on SPSS

Please help
