Emma's On-the-Go, a large convenience store, has to decide where in the store to put its candy bar display rack. The manager at Emma's experiments with a selection of different locations, choosing a sample of days at each location. Each day, the manager records the amount of money brought in from the sale of candy bars. It's possible to test whether there is a difference in the mean daily sales for the different locations by doing a one-way, independent-samples ANOVA test. The variable of interest is the daily sales, in dollars, from candy bars at Emma's. In the ANOVA test, the "groups" are the different locations, and the "samples" are the daily candy bar sales actually examined by the manager. 122 (a) The following ANOVA table gives a summary of such an ANOVA test.
