As the director of sales and marketing at a major retail store, Jane has been conducting direct marketing campaigns by sending emails containing discount coupons and other offers to the company's existing and likely future customers. His department has also placed ads on TV and popular online social media sites. As a result, her company has accumulated large amount of data on past many years of marketing campaigns, including whether each type of campaign was financially successful or not, the amount spent on each campaign, and the resulting revenue generated.
