SPSS pathway for independent samples t-test

Analyse → Compare Means and Proportions → Independent Samples

DV → Test Variable(s), Group → Grouping variable, look for Sig

SPSS pathway for Paired Samples t

Analyse → Compare Means and Proportions → Paired Samples t

Pair the two measurements

SPSS Pathway for RM ANOVA

Analyse → General Linear Model → Repeated Measures
