Workspace Node: Breakdown and One-Way ANOVA Individual Tables - Results - Correlations Tab

In the Breakdown and One-Way ANOVA Individual Tables node dialog box, under the Results heading, select the Correlations tab to access options to review and compare the correlations.

Within-group correlations & covariances

    1. If more than one dependent variable is selected for the current analysis, select this check box to compute the within-group correlation matrices for those variables. The Select groups dialog box will display.
    1. Select the group for which to compute the correlation matrix, or you select to display a cascade of spreadsheets (displaying the correlation matrices for multiple groups).

The default results spreadsheet graph (via Graphs of Input Data) for this option is the scatterplot As a result, within the spreadsheet containing a within-group correlation matrix, you can produce a scatterplot of selected within-group correlations.

Options

This group box contains options for the Within-group correlations matrices (see above). Specifically, you can determine an alpha (p) value for highlighting significant correlations, compute within-group covariance matrices, or report various additional statistics (e.g., pairwise N, means, standard deviations).

Compute & display significance (p)-values

Select this check box to compute a matrix of p significance values for each correlation matrix.

Compute & display covariances

Select this check box to compute a matrix of covariances for each correlation matrix.

Options for pairwise MD deletion

The options in this group box are meaningful and available only if pairwise deletion of missing data was selected on the Specifications - Quick tab prior to processing the data.

Display pairwise N

Select this check box to display a matrix of valid N for each correlation matrix.

Display pairwise means

Select this check box to display a matrix of pairwise means for each correlation matrix.

 For each correlation, those means will be computed from all cases that were included in the computation of the respective correlation coefficient.

Display pairwise standard deviations

Select this check box to display a matrix of pairwise standard deviations for each correlation matrix.

 For each correlation, those standard deviations will be computed from all cases that were included in the computation of the respective correlation coefficient.

p-value for highlighting

The default p-value for highlighting is .05. You can adjust this p-value by entering a new value in the edit box or using the microscrolls.

For more details on p-value, see Elementary Concepts.

Categ. scatterplots

    1. Select this check box to produce a cascade of categorized scatterplots.  A standard variable selection dialog box will display.
    1. Select variables for the plot from among the list of dependent variables in the current analysis.

A categorized scatterplot will be produced for each selected variable.

Save stacked matrix

Select this check box to display the Select groups dialog box, which is used to select the groups you want included in the stacked matrix (also called a multiple correlation matrix).

Options / C / W

See Common Options.

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.
