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.
A t test is a statistical hypothesis test that assesses sample means to draw conclusions about population means. Frequently, analysts use a t test to determine whether the population means for two groups are different.
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.
31 sty 2020 · You can compare your calculated t value against the values in a critical value chart (e.g., Student’s t table) to determine whether your t value is greater than what would be expected by chance. If so, you can reject the null hypothesis and conclude that the two groups are in fact different.
The value where the row and column intersect is the t critical value. For example, if you have 7 degrees of freedom and are conducting a test at the 0.05 significance level, the critical t-value is 1.895.
6 sty 2020 · 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) The alpha level of the t-test (common choices are 0.01, 0.05, and 0.10)
