Now that you are aware that the average payment is $19.48, you can stratify the amounts to give you a range of how many transactions occurred in each range as displayed in Figure 3.11. Visa, MasterCard, and American Express (AME) are accepted but are not as popular with their customers. We can see in Figure 3.10, that debit cards are used most frequently, followed by cash payments. The tender or payment type can be summarized to identify the number of transactions for each category and total the amounts as shown in Figure 3.9.

If you were to apply sampling techniques, you would want to pull more samples from after the noon hour. or at noon, depending on the day of the week. This makes perfect sense, since the business opens either at 11:00 a.m. The most payments are processed after the noon hour, with 80,609 or 95 percent of transactions taking place. The payment time also provides valuable information in Figure 3.8. The monthly and daily number of transactions are also displayed in field statistics, as shown in Figure 3.7. Most frequent payments and sales occur on Fridays and September was the best month for the client. Therefore, theДЇIGURE 3.6 Isolating the Field Statistics of the Payment Amount The most frequent or common day of the week is Friday and the most common month is September. The statistics for the date field shows the date of the earliest and latest record so you know the date range for the data you will be analyzing.

A discussion of the sample and population standard deviation values follows in Chapter 4. Both the minimum value and maximum value amount should be examined in detail. Note that the average payment for the sales is $19.48. By putting your cursor over items it turns into a hand icon, and those items can be clicked on to drill down to detail levels and display the records pertaining to those items. The net value is the total of the field or column, which equals the control total. The only numeric field that is of use is the pay amount field, which we will look at closer in Figure 3.6.ДЇIGURE 3.5 Field Statistics of the Payment Tender File
