Pelican Stores Case

Pelican Stores, a division of National Clothing, is a chain of women’s apparel stores operating throughout the country. The chain recently ran a promotion in which discountn coupons were sent to customers of other National Clothing stores. Data collected for a sample of 80 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. Most of the variables shown the data are self-explanatory, but two of the variables require some clarification.

Items: The total number of items purchased

Net Sales: 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.
