QI Macros built in code is smart enough to: Once you create a control chart using QI Macros, you can easily update the control limits using the QI Macros Chart Tools menu. Calculate the Lower Control Limit (LCL), which is the mean of means minus three times the standard deviation. There are seven main types of control charts (c, p, u, np, individual moving range XmR, XbarR and XbarS.) Premium Content You need a subscription to comment. Calculate the upper and lower XmR control limits using the sequential deviation; Lower XmR Control Limit(LCL): LCL X = X – 3 ⋅ Š; Upper XmR Control Limit(UCL): UCL X = X + 3 ⋅ Š; mR Chart Calculations. Control limits are the "key ingredient" that distinguish control charts from a simple line graph or run chart. A control chart is a statistical tool that is used to chart data points over time and zeros in on points that are outside of the normal range (outliers). The P chart control limits vary for each sample based on its sample size, but are easily calculated using our SPC software. The formula for sigma varies depending on the type of data you have.
