p-Chart
Attribute control chart monitoring the proportion of nonconforming units when sample size may vary.
Examples
- 01Because daily output varies, the call-center audit uses a p-Chart of the share of wrong orders.
- 02Supplier quality reviews the p-Chart of rejected parts each week, with daily sample sizes between 300 and 800.
- 03When the p-Chart shows a sudden rise in rejects, the team checks whether a new batch of raw material was introduced.
