Webcontrol charts may be accepted uncritically by some and viewed with scepticism by others. In this article Dr Moore shows how certain departures from normality can affect the probabilities associated with control limits calculated by normal theory. These examples should serve as a warning against the too rigid interpretation of such control limits. WebIn addition, the most widely used control charts and process capability statistics are based upon theoretical assumptions about the normality of the process data. Since the assumption of normality is critical prior to using many statistical tools , it is often suggested that tests be run to check on the validity of this assumption.
