Workspace Node: t-Test, Dependent Samples - Results - Advanced Tab

In the t-test, Dependent Samples node dialog box, under the Results heading, select the Advanced tab to access the following options.

Element Name Description
Summary: T-tests Select this check box to compute the t-tests for dependent samples and display the results in a spreadsheet. The detail and formatting of the results depend on the selections on this tab.
Box & whisker plots Select this check box to produce a cascade of box and whisker plots for the Variables; one box plot for each variable in the first list vs. each variable in the second list will be produced. Details about this plot depend on the setting on the Options tab. Box and whisker plots summarize the distribution of the dependent variable for each group. Specifically, each group will be represented by one box and whisker "component" which is made up of three "parts":
  1. A central line to indicate central tendency or location;
  2. A box to indicate variability around this central tendency;
  3. Whiskers around the box to indicate the range of the variable.
Display The options in the Display group box determine the detail and formatting of the t-test for dependent samples results spreadsheet.
Matrix of t-tests When the Matrix of t-tests option button is selected, three summary results spreadsheets will be produced, reporting for each pair of variables (from the two lists) the significance level (p-value) for the respective t-value, the mean difference, and the t-values for the respective difference.
Detailed results When the Detailed results option button is selected, one summary results spreadsheet will be produced, reporting for each t-test the means, standard deviations, valid N, etc.
Display long variable names Select the Display long variables names check box to display the long variable names (if any, see Variable Specs Editor) along with the short names in the first column of the result spreadsheets. If no long variable names have been specified for any of the selected variables, then the setting of this check box will have no effect.
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.
CI for estimates Select this check box to compute confidence interval estimates for the differences between means. You can request confidence limits for any p-value using the corresponding field. By default, the 95% confidence limits (p=.05) is computed. For more information on confidence limits, see Descriptive Statistics - "True" Mean and Confidence Interval.
