08068 IUPAC Gold Book - control chart 10.1351/goldbook.08068 08068 current 1 Chart with control limits on which some statistical measure related to a series of samples is plotted in a particular order to steer the process with respect to that measure. The particular order is usually based on time or sample number order. Repeated sampling may be avoided where in-situ measurements are applicable. The control chart operates most effectively when the measure is a process variable which is correlated with an ultimate product or service characteristic. Examples of control charts are Shewhart means chart, Shewhart range chart, and cumulative sum control chart. Control charts are commonly used in the regular monitoring of the performance of a measurement procedure, as part of the laboratory's internal quality control.
