## Use of control charts for attributes

Control Charts for Variables: A number of samples of component coming out of the process are taken over a period of time. Each sample must be taken at random and the size of sample is generally kept as 5 but 10 to 15 units can be taken for sensitive control charts.

26 Jul 2018 More details about the designing and the use of attribute control charts can be read in Epprecht and Costa, Laney, Epprecht et al., Wu et al.,  Control chart variables using only the recent 24 samples: Use average sample size. If no standard is given, estimate c then use the following parameters:. For example, we may use this chart to control the number of units produced with minor For attribute control charts (C, U, Np, or P charts), the estimate of the  Control charts have two general uses in an improvement project. to change than attribute control charts (those that measure variation on a discrete scale). 27 Dec 2017 The application of statistical process control charts provides a better understanding of the behavior of any operation and is broadly applicable  Charts for Variables 2.
