There are three Case Studies that are presented here in conjunction with the STAT 504 online materials.

• The Penn State Ice Cream Study
• Stress and Smoking Study
• Water Level Study

All three of these feature Dr. William Harkness, Professor Emeritus of Statistics giving a video interview about each of these three cases. SAS code, datasets and other materials related to these cases are presented as the case is discussed. Dr. Harkness has taught STAT 504 in residence for many semesters.
