WebSubtract 1 from the sample size. This gives the degrees of freedom (df). If the hypothesis test is one-tailed then use the one-tailed t distribution table. Otherwise, use the two-tailed t distribution table for a two-tailed test. Match the corresponding df value (left side) and the alpha value (top row) of the table. WebT Table. 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%.
