Results - Non-Normal Tab

Select the Non-normal tab of the Results dialog box to access the options described here. Note that this tab is not available for Short Run charts, moving average and exponentially weighted moving average charts, or CuSum charts; this tab is also not available if the input data file contains aggregated data (sample means and ranges or standard deviations; in that case skewness and kurtosis statistics are not available, and non-normal charts and related results cannot be computed). Also note that when sets are specified, either via the Results dialog box - Sets tab or the Defining Variables dialog box - Sets tab, skewness and kurtosis are calculated from the total sample not the data in individual sets. See also, Process Analysis for process capability analysis options for non-normal data.

Specs for non-normal control limits

For Skewness and Kurtosis, you can select to have the values Computed from data, or you can select User defined and enter the number in the box or use the microscrolls to adjust the number.
