QC_X-MR_Chart.hwr  QC X-MR Chart preview

Spread Report that displays and graphs a daily variable's raw values for a month with UCL and LCL (Mean +- 3 Standard Deviations) and the moving range (difference between succesive points).  An individuals and moving range (X-MR) chart is a pair of control charts for processes with a subgroup size of one. Used to determine if a process is stable and predictable, it creates a picture of how the system changes over time. The individual (X) chart displays individual measurements. The moving range (MR) chart shows variability between one data point and the next. Individuals and moving range charts are also used to monitor the effects of process improvement theories.
