29 kwi 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.
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.
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%
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.
To use the t-table, simply match the degrees of freedom with the area in the upper tail. For example, matching up 6 degrees of freedom with an area in the upper tail area of .05, you get a t-value of 1.9443. This means that under a t-distribution with 6 degrees of freedom, the area to the right of 1.9443 is .05.
