WebJan 31, 2024 · When to use a t test. A t test can only be used when comparing the means of two groups (a.k.a. pairwise comparison). If you want to compare more than two groups, or if you want to do multiple pairwise comparisons, use an ANOVA test or a post-hoc test.. The t test is a parametric test of difference, meaning that it makes the same assumptions … Webthe value specified by H0 is called a two-sided (or two-tailed) test, e.g. H0: µ = 100 HA: µ <> 100 I. Whether you use a 1-tailed or 2-tailed test depends on the nature of the problem. Usually we use a 2-tailed test. A 1-tailed test typically requires a little more theory.
