To calculate a two-sided confidence interval for a t-test, take the positive critical value from the t-distribution table and multiply it by your sample’sstandard error of the mean. Then take the sample mean and add and subtract the product from it to calculate the upper and lower interva...
T-Distribution Table (One Tail). For more info on the parts of the t table, including how to calculate them, see: degrees of freedom and alpha level.
Statistics - T-Distribution Table - The critical values of t distribution are calculated according to the probabilities of two alpha values and the degrees of freedom. The Alpha (a) values 0.05 one tailed and 0.1 two tailed are the two columns to be comp

Hence we see that the critical value corresponding to ourtin the t-distribution table is 1.711. In a similar way, you can also map critical values for two-tailed tests with the only difference being that you have to select the two-tailed row of alpha values instead. The rest of the step...

I also chose the Lanczos approximation for solving the gamma function for the t-distribution PDF. The algorithm for the approximation was obtained from page 214 of "Numerical Recipes in C, 2nd Edition". Here is an example that shows you how to generate the z-table that contains the probabili...
