In This Topic

You can save statistics from your analysis to the worksheet so that you can use them in other analyses, graphs, and macros. Minitab stores the selected 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.

The statistics that are available for storage depend on the options that you select for the analysis. For more details on any of these statistics, go to All statistics and graphs.
