Problem:
At a family gathering, Dan Kessler, the manager of an IGA grocery store, got into a conversation with his brother-in-law, who supervises a large number of data-entry workers at a public utility company. The brother-in-law mentioned that his company had recently begun programming background music into the data-entry workers? room with the result that productivity had increased and the number of errors had decreased. Kessler thought that music within a grocery store might have an impact on customers. Specifically, he thought that customers might stay in the store longer if slow, easy-to-listen-to music were played. After some serious thought, he started thinking that he should hire a business researcher to design an experiment for testing the influence of music tempo on shopper behavior.
Operationalize the independent variable music tempo. What dependent variables do you think might be important in this study?
Develop a hypothesis for each of your dependent variables.
