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.

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.
- Covariance matrices
- Store the estimated covariance matrices. Minitab stores the values in the matrix COVA. If your control chart includes stages, Minitab stores a separate matrix for each stage.

- 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 and CENL_1.
- Control limit values
- Store the control limit values. Minitab stores these values in the column CONL, CONL_1, and so on.
- 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 each test for special causes. Minitab stores a 1 if the point fails a test and a 0 if the point does not fail the test. Minitab stores these values in the columns TRES, TRES_1, and so on.
- Decomposed T² values
- Store the decomposed T
^{2}values. One value is stored for each plotted point. Minitab stores one column of values for each variable in the chart. The column names begin with DECO.
