			'''Control limits''' are horizontal lines drawn on an statistical process control chart, usually at a distance of ±3 standard deviations of the plotted statistic from the statistic's mean.

	For normally distributed statistics, the area bracketed by the control limits will on average contain 99.73% of all the plot points on the chart, as long as the process is and remains in statistical control.
