ANOVA/MANOVA Quick Specs - Quick Tab

Select the Quick tab of the ANOVA/MANOVA Quick Specs dialog box to access the options described here. The specific options that are available in this dialog box depend on the Type of analysis selected on the Quick tab of the General ANOVA/MANOVA dialog box. For alternative ways of specifying designs in ANOVA, see Methods for Specifying Designs.

Variables

Click the Variables button to display the standard variable selection dialog box. Depending on the Type of analysis selected on the General ANOVA/MANOVA - Quick tab, Statistica will prompt you to select one or more dependent variables and up to four categorical predictor variables (grouping variables or factors in the design). For example, if you select One-way ANOVA on the General ANOVA/MANOVA - Quick tab, you will be prompted to enter one or more dependent variables and a single predictor variable. Note that in the ANOVA module, you can only specify up to four categorical predictors. If you want to specify five or more categorical predictors, use the General Linear Models module. For details concerning different types of designs, and the distinction between continuous and categorical predictor variables, see the GLM Introductory Overview.

Within effects

Click the Within effects button to display the Specify Within-Subjects Factor dialog box. In this dialog box, specify the within-subject (repeated measures) factor and the respective number of levels (see also, Notes for a discussion of repeated measures ANOVA). In short, the variables in the dependent variable list are assigned to levels for the repeated measures factor. Note that in the ANOVA module, you can only specify one within-subject (repeated measures) factor. If you want to specify multiple repeated measures factors, use the General Linear Models module. This button is only available if you have selected Repeated measures ANOVA as the Type of analysis on the General ANOVA/MANOVA - Quick tab.

Factor codes

Click the Factor codes button to display the Select Codes for Indep. Vars (Factors) dialog box for selecting the codes identifying the levels for the categorical predictor variables (grouping variables). Codes must be integer values or text labels (but can be dates, times, etc.), and at least two codes must be specified for each categorical predictor variable.

Between effects

Click the Between Effects button to display the GLM Between Effects dialog box. In this dialog box, specify the factorial degree of your design. This button is only available if you have selected Factorial ANOVA or Repeated measures ANOVA as the Type of analysis on the General ANOVA/MANOVA - Quick tab.

If the design for the categorical predictor variables needs to be customized, click the Syntax editor button (in the ANOVA/MANOVA Quick Specs dialog box) to further customize the model via command syntax. For alternative ways of specifying designs in ANOVA/MANOVA, see Methods for Specifying Designs.
