Sampling is the bread and butter of a significant portion of audit work. As a team (or as a class), list several of the most common audit techniques as well as fraud investigation methods. For example, searching for missing invoice numbers or sending accounts receivable confirmation letters are two common techniques. Comparing employee addresses with vendor addresses and establishing an anonymous tip line are common fraud investigation techniques.

Discuss the issue by arguing for one of the techniques. You can argue why sampling is the best option for analysis and or argue why full- population analysis must be done. At the end, determine what percentage of audit techniques are best performed with full-population analysis.
