Question: The regional manager for Macy's is experimenting with two new end-of-aisle displays of the same product. An end-of-aisle display is a common method retail stores use to promote new products. You have been hired to determine which is more effective. Two measures you have decided to track are which display causes the highest percentage of people to stop and, for those who stop, which causes people to view the display the longest. Discuss how you would gather such data.
