One-Way Comparative Pareto Plot<br />

This section uses the contamination data called Failure2.jmp in the <strong>Quality</strong> Control sample data folder. This<br />

table records failures in a sample of capacitors manufactured before cleaning a tube in the diffusion furnace<br />

<strong>and</strong> in a sample manufactured after cleaning the furnace. For each type of failure, the variable clean<br />

identifies the samples with the values “before” or “after.” It is a classification variable <strong>and</strong> has the X role in<br />

the Pareto Plot launch dialog.<br />

Figure 11.11 Failure2.jmp Pareto Launch Dialog<br />

The grouping variable produces one Pareto plot window with side-by-side plots for each value of the X,<br />

Grouping variable, clean. You see the two Pareto plots in Figure 11.12.
