How to create individual moving range chart
WebThe individual (X) chart displays individual measurements. The moving range (MR) chart shows variability between one sample and the next. Individuals and moving range charts are also used to monitor the effects of process improvement theories. The Moving range chart creates range values to plot by finding differences between consecutive samples. WebIn this video, we'll continue exploring individuals and moving range charts. Our learning objective is to create centerlines for the normally distributed X and moving range chart. We'll use a case study to explore this further. A quality improvement team has been working to minimize variation in chrome thickness in the a plating operation.
