By default, the Rules report is sorted in decreasing order by Confidence. However, association rules with extremely high confidence also tend to have a higher number of items in the condition set. Since you want to view association rules with smaller condition sets, sort the report by Confidence, but in increasing order.

Figure 20.3 Frequent Item Sets Report
The Frequent Item Sets report shows that 36% of customers purchased avocados. The Rules report in Figure 20.2 shows that 58% of these customers also bought artichokes. Because of the large proportion of customers who follow this behavior, the grocery store management might use this information to strategically locate avocados and artichokes.
