# Test Options (Related-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.
