Capability Analysis (Binomial) Results - Advanced Tab

Select the Advanced tab in the Capability analysis (Binomial) results dialog box to access options to create individual summary spreadsheets and graphs, which are summarized into a single graph document via the Observed Capability Summary option on the Quick tab.

P chart

Click this button to create a p chart of the percentage or rates; see also the P Chart topic in the Glossary.

In general, this chart is useful to determine that, overall, the process is (or is not) in control.

Rate of Defectives

Click this button to create a scatterplot of defect rates or percentages vs. sample sizes, if unequal sample sizes were encountered, or a scatterplot of observed defects vs. expected defects, if fixed sample sizes were specified.

Cumulative % Defective

Click this button to create a chart of the cumulative percent defectives across samples.

This chart is useful to determine if a sufficient number of samples were taken to estimate a stable value of the percent defective, or the defect rate. This plot is useful to determine if the chosen distribution is appropriate for the respective data, and also enables you to determine the quality of the process relative to the specified upper specification limit.

Distribution of %Defective

Click this button to create a histogram (distribution) of the percent defective.
