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.
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.
