### Interpreting Histograms

Brian runs a small business selling coffee to morning commuters. Like any other small business owner, he would like to increase his traffic. He decides to offer a “buy 10, get one free” punch-card promotion, and figures that if he gives double credit to customers for coffees purchased on days with generally slower sales, he can increase his overall traffic. If the histogram below represents the average number of coffees sold during a week, what can he conclude about the best and worst day(s) to offer “double punches”? How would you describe the shape of his histogram? Does the shape reveal any particularly useful data in this instance?This lesson will help you become familiar with using histograms. At the end of the lesson, we will return to this question to apply your skills.
