Given below is the T Table (also known as T-Distribution Tables or Student’s T-Table). The T Table given below contains both one-tailed T-distribution and two-tailed T-distribution, df up to 1000 and a confidence level up to 99.9%
The t-distribution, also known as Student’s t-distribution, is a way of describing data that follow a bell curve when plotted on a graph, with the greatest number of observations close to the mean and fewer observations in the tails.
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.

The t-distribution table is a table that shows the critical values of the t distribution. To use the t-distribution table, you only need to know three values: The degrees of freedom of the t-test. The number of tails of the t-test (one-tailed or two-tailed)
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%. Use this T-Distribution Table to lookup T critical value for confidence level & degrees of freedom for one tail & two-tails.
T-Distribution Table (One Tail). For more info on the parts of the t table, including how to calculate them, see: degrees of freedom and alpha level.
t-distribution Table. The t-distribution table (or Student’s t-table) provides critical values for the t-distribution, primarily used in hypothesis testing and confidence intervals. The critical t-value can be found in the table below for a chosen significance level, typically alpha=0.05.
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).
