Table 2.18 shows a protion of the data set. 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 & customers who made a purchase but did not use a discount coupon are referred as regular customers, management considers the sales made to people presenting the promotional coupons as sales it would not otherwise make.
