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:

Analyze > Nonparametric Tests > Legacy Dialogs > K Independent Samples...

  1. Select one or more scale, numeric test variables.
  2. 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.
