Determine calculated statistics

You can store various calculated statistics in the worksheet for review and to use for future analyses. Examples of uses for stored statistics include the following:
  • Store the mean and the standard deviation in the worksheet to use as historical parameters for a future control chart.
  • Store the values for the control limits in the worksheet and then format the column to show more decimal places.
  • Store the subgroup sizes in the worksheet so that you can see how much they vary.

To store values for a chart, click the options button in the main dialog (for example, Xbar Options) and then click the Storage tab.
