There are so many datasets available that it seems difficult to sort through them all and identify the best ones to use when teaching an introduction to statistics class. What are your favorite datasets to use when teaching statistics?
I want the students to have some interesting and fun datasets to work with when experimenting with data visualization, constructing confidence intervals, hypothesis testing, etc.
It's possible this question will be closed as being a duplicate of this question or for being opinion-based, but I'd like to know the specific datasets that you love to use when teaching. For example, DASL has been mentioned, but DASL is large -- which dataset within DASL do you like?
