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?

With this sample size (and number of items/questions), any statistical analysis would be questionable. However, from a purely descriptive perspective, the item analysis might suggest which are the easiest and the hardest. It probably would not let you do any more refined ranking of the item-difficulty.
