Select the Descriptives/plots tab of the Gage capability results dialog box to access the options described below.

Descriptive stats (by operator)

Select the Descriptive stats (by operator) button to create a spreadsheet that contains the following values broken down by operator: Valid N, Mean, Standard Deviation, Variance, Minimum, and Maximum.

Box & whisker plot

Click the Box & whisker plot button to produce a plot in which you can examine the distribution of measurements across operators. For each operator, this plot indicates the maximum and minimum measurements (Min/Max, shown as whiskers), the 25th and 75th percentile (25/75%, shown as a box), and the median (indicated by a square point marker). Note that you can select the desired method of computing percentiles in the Options dialog box - Analyses/Graphs: Limits tab (accessible by selecting Options from the Tools tab or menu). For more information, see Percentile Calculation Options in Statistica.

Variability plot

Click the Variability plot button to create the standard plot to summarize the results of a study with multiple trials. Each point in this plot represents the deviation of the respective measurement from the average rating of the respective part (across trials and operators). The line within each box represents the average deviation of the respective operator from the average ratings by all operators.
