WebThe normal distribution assumes that the population standard deviation is known. The t- distribution does not make this assumption. The t- distribution is defined by the degrees of freedom. These are related to the sample size. The t- distribution is most useful for small sample sizes, when the population standard deviation is not known, or both. WebJan 6, 2024 · When you conduct one t-test, her can collate to examination statistic from the t-test to the critical value from the t-Distribution table. If the examination statistic is greater than the critical value found in the table, then you pot reject the null hypothesis of the t-test and conclude so the results of the test are statistically significant.
