Test that assumes data are normally distributed within groups

To Obtain an Independent-Samples T Test

This feature requires the Statistics Base option.

1. From the menus choose:

   Analyze > Compare Means > Independent-Samples T Test...

2. Select one or more scale, numeric test variables. A separate t test is computed for each variable.
3. Select a dichotomous grouping variable (a categorical variable that divides cases into two groups).
4. Click Define Groups and specify the values of the grouping variable that define the two groups.

The grouping variable can be a string (alphanumeric) variable or a numeric variable that uses numeric codes to represent categories (e.g., 0=Male, 1=Female).
