I'd also like to throw my support behind this question from the BVD test
bank. Too often my students come in with the mindset that all answers in a
math class must be absolute (which isn't necessarily their fault!), and it
is very difficult to break them of this habit.

The test questions that accompany the BVD text are GREAT for making sure
that students understand the subtlties, and help to separate the "I can do
the mechanics" students from the "I understand what is really going on"
students (of course, that means that I know who to focus on so I can move
students from the former camp to the latter camp). This frustrates them, but
it's good for them. The world is uncertain, and stats is finally a class
where students can express their uncertainty mathematically. It's a
transition, but if you don't teach your students to see the subtlties in
arguments and to write and think in a way that allows for natural
variability, then Stats might as well be yet another math class - plug,
chug, move on to the next question.
