Test Options (Independent-Samples Nonparametric Tests)
Significance level. This specifies the significance level (alpha) for all tests. Specify a numeric value between 0 and 1. 0.05 is the default.
Confidence interval (%). This specifies the confidence level for all confidence intervals produced. Specify a numeric value between 0 and 100. 95 is the default.
Excluded Cases. This specifies how to determine the case basis for tests. Exclude cases listwise means that records with missing values for any field that is named on any subcommand are excluded from all analyses. Exclude cases test by test means that records with missing values for a field that is used for a specific test are omitted from that test. When several tests are specified in the analysis, each test is evaluated separately.
