A repeated measures t-test is used when each subject participates in both conditions of an experiment. This is because the repeated measures design eliminates individual differences between subjects, which increases the power of the statistical test. The between-subjects t-test is used when different groups of subjects are compared, while the between-conditions t-test is not a commonly used term in inferential statistics. The t-test for independent groups is used to compare two independent samples.
