Types of Control Charts There are two main types of control charts that utilize the mean and standard deviation as some of the quality determinant parameters.

The quality control activity during production consists of taking samples from the run continuously, taking measurements on the samples immediately, and then plotting them rapidly on a Shewhart Chart.

Control chart- a time-ordered plot of sample statistics, used to distinguish between random and nonrandom variability Control limits- the dividing lines between random and nonrandom deviations from ...

Many types of control charts have an ability to detect process changes that can weaken over time depending on the past data observed. This is often referred to as the "inertia problem." We propose a ...
