Means/Anova and Means/Anova/Pooled t
The Means/Anova option performs an analysis of variance. If the X factor contains exactly two levels, this option appears as Means/Anova/Pooled t. In addition to the other reports, a Pooled t-test report assuming pooled (or equal) variances appears.
The t-test report appears only if the Means/Anova/Pooled t option is selected.
