WebJan 6, 2024 · And t-distribution table is one table that shows the critical values of the thyroxin distributing. Up use the t-distribution table, you must need to know three values: The degrees of freedom off the t-test; The number of tails to the t-test (one-tailed or two-tailed) The alpha level of the t-test (common choices live 0.01, 0.05, plus 0.10) WebThe critical value of t at a specified level of significance (α) is calculated for both left & right side of the mean of t-distribution but the α value is divided by 2 and corresponding critical value of t is derived from the t-distribution table for both halves. For example, t 0.5 of single tailed test equals to t (0.25) of two tailed test ... lee ashforth
