Both repeated measures ANOVA and dependent samples t-test are appropriate for comparing means from twin samples where each twin in a pair belonged to a different group from the other twin. Repeated measures ANOVA can be used if there are more than two groups, while dependent samples t-test is appropriate if there are only two groups. Therefore, the best choice is either repeated measures ANOVA or dependent samples t-test, depending on the number of groups being compared.
