The V-Mask CUSUM Control Chart
CUSUM charts can be one-sided or two-sided. One-sided charts detect a shift in one direction from a specified target mean. Two-sided charts detect a shift in either direction.
Follow the instructions in Example of a V-Mask CUSUM Chart to produce the results shown in Figure 6.5.
Figure 6.5 Example of a Two-Sided CUSUM Chart
Note the following:
•
If you use the grabber tool and click on a point, the shift and V-mask adjust to reflect the process condition at that point.
•
If you add new data to the data table for an existing CUSUM chart, the corresponding chart updates automatically.
For information about additional options, see V-Mask CUSUM Control Chart Platform Options.
