Chapter 15 Performing Categorical Response Analysis 391
Categorical Reports
Multiple Response
Suppose that the defects for each unit are entered via a web page, but since each unit rarely has more than
three defect types, the form has three fields to enter any of the defect types for a unit, as in
Failure3MultipleField.jmp, in the Quality Control folder.
Select the three columns containing defect types (Failure1, Failure2, and Failure3), and click the Multiple
Response button. After specifying clean and date as X, Grouping variables, click OK to see the analysis
results. Figure 15.4 lists failure types and counts for each failure type from the Multiple Response analysis.

Categorical Reports
Report Content
The Categorical platform produces a report with several tables and charts. Frequency, Share of Responses,
Rate Per Case tables, and a Share Chart are included by default. You can also select a Frequency Chart. A
Crosstab Format, instead of a Table Format can also be selected. The defect data for Failure3Freq.jmp is
illustrated below.
The topmost table is a Frequency count table, showing the frequency counts for each category with the
total frequency (Responses) and total units (Cases) on the right. In this example, we have total defects for
each defect type by the 7 batches. The last two columns show the total number of defects (Responses) and
the total number of units (Cases).
The Share of Responses table is built by dividing each count by the total number of responses.
