T-Test for Dependent Samples - Advanced tab
Select the Advanced tab of the T-Test for Dependent Samples dialog box to access options to determine the detail and formatting of the t-test for the dependent samples results spreadsheet as well as the p-value for highlighting.
Summary: T-tests
Click this button 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
Click this button to produce a cascade of box and whisker plots for the variables.
First, the Box-Whisker Type dialog box that contains options for the box and whisker type displays, with ne box plot for each variable in the first list vs. each variable in the second list.
Box and whisker plots summarize the distribution of the dependent variable for each group.
Specifically, each group is represented by one box and whisker component, which is made up of three parts:
Display
The options in this group box determine the detail and formatting of the t-test for dependent samples results spreadsheet that is produced when you click the Summary button.

When this option button is selected, click the Summary button to produce the following three summary results spreadsheets reporting for each pair of variables (from the two lists):
Detailed results
When this option button is selected, click the Summary button to produce one summary results spreadsheet reporting for each t-test:
Display long variable names
Select this check box to display the long variable names (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, the setting of this check box has 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.
