Workspace Node: Descriptive Statistics - Results - Categ. Plots Tab

In the Descriptive Statistics node dialog box, under the Results heading, select the Categ. Plots tab to access the following options.

Categorized box & whisker plots

Select this check box to produce a cascade of categorized box and whisker plots for the selected variables, one plot per selected variable. You are first prompted to select up to three categorical variables via a standard variable selection dialog box. The Select codes for the grouping variables dialog box will next be displayed in which you specify the specific groups of each of the categorical variables for which you want graphs to be produced. For each selected variable (via the Variables button on the Specifications - Quick tab), STATISTICA will produce a box and whisker plot broken down (categorized) by the categorical variables.

Categorized means (interaction) plots

Select this check box to produce a standard interaction plot of means by one, two, or three categorical variables. You are first prompted to select up to three categorical variables via a standard variable selection dialog box. The Select codes for the grouping variables dialog box will next be displayed in which you specify the specific groups of each of the categorical variables for which you want graphs to be produced. If one ("dependent") variable was selected via the Variables button (on the Specifications - Quick tab), you can specify up to three categorization variables. If more than one variable was selected via the Variables button, up to two categorization variables can be selected; the different (dependent) variables will be represented by different line patterns (colors) in the graph.

Confidence interval

The default value is 95%, but you can specify another confidence interval for the Categorized means (interaction) plot.

Categorized histograms

Select this check box to produce a cascade of categorized histograms for the selected variables, one plot per selected variable. You are first prompted to select up to two categorical variables via a standard variable selection dialog box. The Select codes for the grouping variables dialog box will next be displayed in which you specify the specific groups of each of your categorical variables for which you want graphs to be produced. For each selected variable (via the Variables button on the Specifications - Quick tab) Statistica produces a histogram, broken down (categorized) by the categorical variables (e.g., separately for males and females for each ethnic group).

Categorized scatterplot

Select this check box to produce a cascade of categorized scatterplots for selected pairs of variables, one plot per pair. You are first prompted via a standard variable selection dialog box to select two lists of variables (from among those originally selected via the Variables button on the Specifications - Quick tab). Scatterplots will be produced for each variable in the first list with each variable in the second list. Next (via another standard variable selection dialog box) you will be prompted to select up to two categorical variables. Then, the Select codes for the grouping variables dialog box will be displayed in which you specify the specific groups of each of your categorical variables for which you want graphs to be produced. Statistica produces a cascade of scatterplots broken down (categorized) by the specified groups in the categorical variables (e.g., separately for males and females for each ethnic group).

Categorized probability plots

The options in this group box will produce a cascade of normal probability plots for the selected grouping variables. Note that, after selecting any of these check boxes, you are first prompted to select up to two categorical variables via a standard variable selection dialog box. Next, the Select codes for the grouping variables dialog box will be displayed in which you specify the specific groups of each of the categorical variables for which you want graphs to be produced.

Normal

Select this check box to produce a cascade of categorized normal probability plots for the selected variables, one plot per selected variable. For more information on how the standard normal probability plot is constructed, see Normal Probability Plots.

Half-normal

Select this check box to produce a cascade of categorized half-normal probability plots for the selected variables, one plot per selected variable. For more information on how the half-normal probability plot is constructed, see Half-Normal Probability Plots.

Detrended normal

Select this check box to produce a cascade of categorized detrended normal probability plots for the selected variables, one plot per selected variable. For more information on how the detrended normal probability plot is constructed, see Detrended Normal Probability Plots.

OK. Click the OK button to accept all the specifications made in the dialog box and to close it. The analysis results will be placed in the Reporting Documents node after running (updating) the project.
