Pelican Stores Pelican Stores, a division of National Clothing, is a chain of women's apparel stores operating through out the country. The chain recently ran a promotion in which discount coupons were sent to customers of other National Clothing stores. Data collected for a sample of 100 in-store credit card transactions at Pelican Stores during one day while the promotion was running are contained in the file named "PelicanStores". The proprietary Card method of payment refers to charges made using a National Clothing charge card. Customers who made a purchase using a discount coupon are referred to as promotional customers and customers who made a purchase but did not use a discount coupon are referred to as regular customers. Because the promotional coupons were not sent to regular Pelican Stores customers, management considers the sales made to people presenting the promotional coupons as sales it would not otherwise make. Of course, Pelican also hopes that the promotional customers will continue to shop at its stores. In the data set, Items refers to the total number of items purchased and Net Sales refers to the total amount ($) charged to the credit card. Pelican's management would like to use this sample data to learn about its customer base and to evaluate the promotion involving discount coupons.
