You can save statistics from your analysis to the worksheet so that you can use the statistics in other analyses, graphs, and macros. Minitab stores the statistics after the last column of data. The names of the storage columns end with a number that increases as you store the same statistic multiple times.
Store these estimates for each chart
If your control chart includes stages, Minitab stores a separate value for each stage.
- Means
- Store the estimated or historical process mean. Minitab stores these values in the column MEAN.
- Standard deviations
- Store the estimated or historical standard deviation. Minitab stores these values in the column STDE.
Store these values for each point
- Point plotted
- Store the value of each plotted point. Minitab stores these values in the columns PPOI and PPOI_1.
- Center line value
- Store the center line values. Minitab stores these values in the column CENL.
- Control limit values
- Store the control limit values. Minitab stores these values in the columns CONL and CONL_1.
- Stage
- Store the name or the number of each stage. Minitab stores these values in the column STAG.
- Subgroup size
- Store the size of each subgroup. Minitab stores these values in the column SSIZ.
- Test results
- Store the results of which points are outside the control limits for a tabular CUSUM or outside the V-Mask for a V-mask CUSUM. Minitab stores a 1 if the point is out of control, a –1 if the point is below the lower control limit, and a 0 if the point is in control. Minitab stores these values in the column TRES.
