Fig. 1.5.6 Categorization of data.Once data are categorized, many sorts of analysis can ensue. One of the typical forms of
analysis is the identification of exceptional data. For example, the analyst may wish to
find all customers who have spent more than $1,000 in the past year. Or the analyst may
want to find days when production peaked over 25 units a day. Or the analyst may want
to find what products were painted red that weighed more than 50 pounds. Fig. 1.5.7
