29 kwi 2022 · Learn how to use Student's t table to find critical values of t for statistical tests and confidence intervals. Download the t table for free and follow the step-by-step guide with examples.
In probability theory and statistics, Student's t distribution (or simply the t distribution) is a continuous probability distribution that generalizes the standard normal distribution. Like the latter, it is symmetric around zero and bell-shaped.
Learn how to use the T Table to find critical values for t-tests with different degrees of freedom and alpha levels. See examples, diagrams and sample questions with solutions.
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.

In regression analysis, the t-distribution is used when testing for a significant relationship between the dependent and independent variables. This test is known as a t-test and the degrees of freedom here is equal to sample minus the number of independent variables (p) minus one (n - p - 1).
Given below is the T Table, otherwise known as the Student’s T-table or T-distribution table. This T table contains both one-tailed T-distribution and two-tailed T-distribution, degrees of freedom up to 1000, and a confidence level up to 99.9%.
