Indicator Group
In some cases, the data is not yet summarized, so there are individual records for each unit. We illustrate this
situation in Failures3Indicators.jmp, located in the Quality Control folder.
With data like this, specify all the defect columns with the Indicator Group button. The X, Grouping
Category columns are clean and date. When you click OK, you get the same output as in the Response
Group example (Figure 15.3).
Multiple Delimited
Suppose that the inspector entered the observed defects for each unit. The defects are listed in a single
column, delimited by a comma (Failures3Delimited.jmp, in the Quality Control folder). Note in the partial
data table, shown below, that some units did not have any observed defects, so the failureS column is empty.
