A bank encouraged customers who have its debit cards to use them more frequently. It collected a sample of customers and found the number of times that each used the debit card during the four-month promotion March–June. To learn whether the average number of charges over this period is different in any month, the bank plans to use a one-way ANOVA. Would this be the right analysis? If not, what should the bank do?
