Statistics (Box-Whisker Type Plots)

Click the Statistics button in the Box/Whisker dialog box (or on the Box/Whisker tab of the Graph Options dialog box) to display the Statistics dialog box. Note that this dialog box can also be displayed by clicking the OK button in the Add Legend dialog box or the Statistics button in the Plot: Variability plot dialog box.

Use these options to add to the graph (e.g., box-whisker plot) the results of a Kruskal-Wallis nonparametric test, or the ANOVA test. Both compare the central tendencies (e.g., means) across the groups for each (dependent) variable. The Kruskal-Wallis test is further described in the context of the Nonparametric Statistics; the ANOVA test is described in the Breakdown Tables section of Basic Statistics, as well as in the General ANOVA/MANOVA section.

Plot

Although all of the options are the same for each plot, you can make changes to each plot independently of the other. Select here the plot to which you want to make changes. Note that this option will only be available if the Statistics dialog box has been displayed via the Insert - Statistics menu (classic menus) or the Stats option on the Insert tab - Legend group (ribbon bar).

Kruskal-Wallis-Test

Select the Kruskal-Wallis-Test check box to include the Kruskal-Wallis test statistic in the plot.

F Test, p

Select the F Test, p check box to include the F test and p statistics (analysis of variance results) in the plot.

Note: When you select statistic(s) to include in your plot, the Add Legend dialog box will also be displayed, which is used to select where and how to attach the statistic(s) to the plot.

Value Format

Use the Value Format group box to select from a variety of number formats to use for the numeric values including General, Number, Date, Time, Scientific, Currency, Percentage, Fraction or Custom. Most of the options in this list have more than one representation, except the General and Percentage options. Some options also allow you to specify decimal information.
