Apr 29, 2022 · Two-tailed tests are appropriate for most studies. If you’re calculating a confidence interval, choose two-tailed. One-tailed tests are used when the alternative hypothesis is directional. A directional hypothesis states that a population parameter is greater than or less than a certain value.

t-distribution table (two-tailed) Example. The mean of a sample is 128.5, SEM 6.2, sample size 32. What is the 99% confidence interval of the mean? Degrees of freedom (DF) is n−1 = 31, t-value in column for area 0.99 is 2.744. The 99% CI is: See also. Values of the Normal distribution. Values of the Chi-squared distribution.

Once you have all three, all you have to do is pick the respective column for one-tail or two-tail from the table and map the intersection of the values for the degrees of freedom (df) and the alpha level. Let us understand how to read the T-Table using an example of an one-tailed test.
