What is a q chart?

A quality chart (q chart) is used to evaluate process stability when counting the fraction conforming.

Example of a q Chart creating using QI Macros add-in for Excel.

q control chart tracks the fraction conforming

The q Chart is used when counting the number of conforming items in a sample versus counting the number of defects in a sample as in the p Chart. q= (1-p). Therefore the UCL and sigma lines can never be greater than 100%.

To run a q Chart in QI Macros, just select your data and run the p Chart.
