## Q-QUIZ OCTOBER 2018

2018-10-16 - **Basics of process capability - test your knowledge!**

Most real processes in practice are no longer normally distributed in long-term analyses. ISO 22514-2 shows how to classify changes in the location and variation of a process. This standard also describes the resulting distribution and calculation methods for C_{p} and C_{pk} or P_{p} and P_{pk}. To simplify matters, the normal distribution serves as an approach to teach the basics of process capability.
