The first piece, the crosstabulation, shows the relative percentage of the order method sales
for each campaign. The Canyon Mule campaign seemed to have an exceptional number of
web and fax orders. The chi-square test results are looking for a pattern of exceptional
order methods for a promotion. The chi-square test shows that the numbers in the crosstab-
ulation are not significantly different. If the company wants to continue the Canyon Mule
campaign, marketers may want to focus on these order methods to increase orders.
