A couple of weeks ago I did your suggested exercise (from Teaching Statistics: A Bag of Tricks) on ‘Guessing the age’, with the additional twist that the people were actors/actresses out of CSI. As well as discussing the data in class, I used it for there first R lab, where they generated simple scatterplots, boxplots and histograms.

In case your interested, the main results where:

1. Watching CSI didn’t seem to affect your guess

2. Females guessed better than males.

3. The vast majority of guesses where too low (unsurprising for actors), except for the youngest actor.

If you are interested you can find my slides/handouts here.

Cool!
