I gave a 12 item true-false quiz (which I created) to my 19 students.
I noticed that some questions were very obviously easier than others, so I decided to run an item analysis. By looking at the item difficulty results, it does seem like that's the case. I am thinking of re-administering the quiz and excluding items with item difficulty below 0.5.
But with such a small sample size, should I even bother with item analysis?
