Test that does not assume data are normally distributed
To Obtain Nonparametric Tests for Several Independent Samples
This feature requires the Statistics Base option.
From the menus choose:
- Select one or more scale, numeric test variables.
- Select a numeric grouping variable (a variable that divides cases into three or more groups).
The grouping variable must be numeric. If your grouping variable is a string (alphanumeric) variable, use Automatic Recode on the Transform menu to convert the string values to integers.
