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.
Find in this t table (same as t distribution table, t score table, Student’s t table) t critical value by confidence level & DF for the Student’s t distribution.
Find the critical value of t in the two-tailed t table. Multiply the critical value of t by s / √ n . Add this value to the mean to calculate the upper limit of the confidence interval, and subtract this value from the mean to calculate the lower limit.
This table contains critical values associated with the t distribution, ta, defi ned by the degrees of freedom and a. a.
curve. critical value. Confidence area captured: 0.90 Confidence level: 90%. Degrees of Freedom. 40. 60. 70. 80.
