I used this example in class today because part of my introduction to
stats involves examples of why statistics makes you think better. It
went reasonably well. I quickly made up a 2x2 chi-square example using
the depression frequencies reported in the article. I also made a link
to the article in the Blackboard site for the course. Although we
haven't covered chi-square yet, I think the example is simple enough
that students can grasp the logic. Here is a link to the spreadsheet.
I like Excel for examples because I can change data vales and
immediately present what happens to the statistics when the change is
made. I did the spreadsheet quickly and I hope there are no errors.
