WebApr 11, 2024 · So, what is a t-test? It is a type of inferential statistic used to study if there is a statistical difference between two groups. Mathematically, it establishes the problem by … In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. It is used in hypothesis testing via Student's t-test. The t-statistic is used in a t-test to determine whether to support or reject the null hypothesis. It is very similar to the z-score but with the difference that t-statistic is used when the sample size is small or the population standard deviation is unknown. For example, the t-statistic is used in estimatin…
