7 sty 2024 · Hypothesis testing with the t-statistic works exactly the same way as z-tests did, following the four-step process of (1) Stating the Hypothesis, (2) Finding the Critical Values, (3) Computing the Test Statistic, and (4) Making the Decision.
The t-test enables us to decide whether the mean of one condition is really different from the mean of another condition. There are two versions of the t-test: (a) dependent-means t-test (also known as the "matched pairs" or. "repeated measures" t-test): use this when the same subjects participate in both conditions of the experiment.
