  1. This t-distribution table provides the critical t-values for both one-tailed and two-tailed t-tests, and confidence intervals. Learn how to use this t-table with the information, examples, and illustrations below the table.

  2. 29 Απρ 2022 · Student’s t table is also known as the t table, t-distribution table, t-score table, t-value table, or t-test table. A critical value of t defines the threshold for significance for certain statistical tests and the upper and lower bounds of confidence intervals for certain estimates.

  3. The resulting value is your critical value. Example: Two-Tailed Test with df = 10 and P = 0.05. For a two-tailed test with 10 degrees of freedom and a significance level of P = 0.05, look for the row labeled "10" and the column labeled "0.05" in the two-tailed section. The critical value is approximately 2.228. Interpreting the Critical Value
