What does marketing research have to do with St. Patrick’s Day?

More than you might think! In fact, William Sealy Gossett developed the famous Student’s t-distribution (or t-test) to monitor the quality of Guinness Stout (He published it as the Student’s t-distribution because Guinness had a policy prohibiting employees from publishing).
