ANALYSIS OF COEFFICIENT VARIATION CONTROL CHARTâS SIMULATION APPROACHED BY NORMAL AND CHI-SQUARE DISTRIBUTION AND T-STUDENT DISTRIBUTION
The purpose of statistical process control (SPC) is to reduce variability. Usually SPC connected with constant mean and standard variation. But, there’re also processes that the mean is not constant. In these cases we need coefficent of variation. There are two methods to approach coefficient of var...
