Instructions
- Specify a value of delta to represent the change in the mean of a process, and a value of n to represent the size of a rational subgroup.
- When you click "Generate & Plot Data": forty data points are generated at random and plotted, the center point, 3 sigma control limits, and average run
length (ARL) are computed and displayed.
- Any points that fall outside the limits are plotted in a different color. In this instance, you will see a message that indicates which
sample number the process is first detected to be out of control.
