Scope and common interpretation errors
For cavity-traceable data analysis, not a substitute for a complete capability study.
High and low groups can cancel in the mean while individuals remain out of tolerance. Mixed process stages also create hard-to-interpret distributions.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Keep grouping fields | Link every value to cavity, time period and method. |
| 2 · Plot within-group data | Review individual values, means and ranges rather than only a grand mean. |
| 3 · Investigate fixed sources | Check tooling, sampling and measurement for shifted groups and start a separate confirmation segment after correction. |
A comparison to avoid misinterpretation
Two cavities near opposite limits can yield an attractive overall mean without proving either cavity stable. Validate them separately.

Frequently asked question
Can the worst cavity be excluded to improve the calculation?
Only a predefined evidence-based exclusion rule can justify removing data.
