Now that you know whether your test is two-tailed or one-tailed, the degrees of freedom (df), and the significance level, you have all the information you need to use the t table. 1. If the test is two-tailed or if you’re calculating a confidence interval, use the first table. If the test is one-tailed, use the second table. 2. The … See more Two-tailed tests are used when the alternative hypothesis is non-directional. 1. A non-directional hypothesis states that a population parameter(such as a mean or regression … See more By convention, the significance level(α) is almost always .05. The α = .05 column is highlighted in the table since it is the most commonly used … See more The degrees of freedom (df) of a statistic are calculated from the sample size (n). The equation you need to use depends on what type of test or procedure you’re performing. See more WebMore information about critical values for the t-distribution : First of all, critical values are points at the tail (s) of a specific distribution, with the property that the area under the curve for those critical points in the tails is equal to the given value of \alpha α. The distribution in this case is the T-Student distribution.
