Glossary Quality Control / Term
One of three time-weighted charts that plots the exponentially weighted moving average. This chart helps to ensure that you do not specify a process as out of control when it is in control, or one in which you do not fail to detect a marked change in the mean. It is useful for detecting small, persistent shifts in a process. This chart is not sensitive to the normality assumption and, therefore, is an ideal chart to use with individual data.
