I am guilty of spoiling my students by usually providing them with
clean data, generated such that distributional assumptions are all met,
there are no out-of-range data, and so on. Every once and a while, however,
I do something that I really should do more often -- I throw into the data
for their assignments a few kinks and expect them to find them. If they do
not screen the data, they don't find them. Of course, the more challenging
question is what to do with the kinky data -- excluding them from the
analysis is often a bad idea.
