WebThe TOST approach can also be used for a one-sample test (and similarly for a two dependent sample test). In this case, we test the equivalence between the mean of a single population and some hypothetical mean μ0. H0: μ – μ0 ≤ θL or μ – μ0 ≥ θU. H1: θL < μ – μ0 < θU. This time we conduct two one-sample t-tests. WebMay 1, 2024 · The test that assumes equal population variances is referred to as the pooled t-test. Pooling refers to finding a weighted average of the two independent sample variances. The pooled test statistic uses a weighted average of the two sample variances. If n 1 = n 2, then S p 2 = ( 1 2 s 1 2 + ( 1 / 2) s 2 2, the average of the two sample variances.
