Chapter 8 Observation Studies
Learning Objectives Understand . . . • When observation studies are most useful. • Distinctions between monitoring. nonbehavioral and behavioral activities • Strengths of the observation approach in research design. • Weaknesses of the observation approach in research design.
Learning Objectives Understand . . . • Three perspectives from which the observer-participant relationship may be viewed. • Various designs of observation studies.

RFID Changes Monitoring “We can certainly understand and appreciate consumer concern about privacy. That’s why we want our customers to know that RFID tags will not contain nor collect any additional data about our customers. In fact in the foreseeable future, there won’t even be any RFID readers on our stores’ main sales floors.” Linda Dillman, EVP & Chief Information Officer, Wal-Mart

Behavioral Observation • “We noticed people scraping the toppings off our pizza crusts. We thought at first there was something wrong, but they said, ‘We love it, we just don’t eat the crust anymore.” • Tom Santor, Donatos Pizza
