How easy is it to take a representative sample?
One of my favorite exercises for intro stats. Students attempt to take a representative sample of words and estimate the mean word length in a passage of text. I've done this for 10 years now, and the result is similar every year. Students tend to oversample big words! [Thanks to the Lock family, authors of Unlocking the Power of Data textbook, for the idea - I just modified the passage to fit my audience,]
