1. Chapter 5 lists a number of ways that secondary data can be used. What are some of those ways and why is each important?

2. Chapter 6 notes that marketers often use bar codes as a way to monitor inventory and gather relevant consumer data concerning product purchases. It is also mentioned that small chips called radio frequency identification devices(RFID) are often used in lieu of bar codes to better track products and consumers. Do you agree that such tracking is ethical? What additional strategies would you suggest that marketers use to track consumer behavior?
