well, without incriminating myself too much, based on my experience it was useful to know sens, spec, ppv, npv. all asked in one question.
also, i had another question that had a term that is not in any of the review books (forgot the actual term), but required a bit of figuring out. had to do with prevalence in a way. i know this doesnt help out any.
i maybe had 5 questions on the whole test it seems in stats.
and a bias question.
