Nonparametric Tests
Nonparametric tests make minimal assumptions about the underlying distribution of the data. The tests that are available in these dialogs can be grouped into three broad categories based on how the data are organized:
- A one-sample test analyzes one field.
- A test for related samples compares two or more fields for the same set of cases.
- An independent-samples test analyzes one field that is grouped by categories of another field.
