THAT'S LIFE - Mediterranean diet

This little piece reports on a medical study of diet and heart attacks. It would be possible in a senior class to perform a hypothesis test on the difference in proportion of heart attacks in the two groups (assuming half of the people in each group).

Students should discuss as well however, other factors which could have affected the results. For example, were the people randomly assigned to the two groups? Did the people given the Mediterranean diet also do other things which might make them more healthy, like get more exercise? How were factors such as family history or geographic locality controlled for?

Where to next?
