I am looking for a Python function (or to write my own if there is not one) to get the t-statistic in order to use in a confidence interval.
Generating random numbers from a t-distribution. Ask Question Asked 6 years, 9 months ago.. faster than the gaussian-only approach for all but the smallest degrees of freedom, is to use the fact that a t distribution is a mixture of Normals, with the mixture distribution being an inverted gamma distribution on the variance. Here's an example in R, where we generate 1,000,000 t(10) variates.

Selected Critical Values of the t-Distribution A test is 2-tailed if you ask the question, 'does population 1 differ from population 2'. Then, if the mean for population 1 is significantly greater or smaller than that for population 2, you reject the null hypothesis. If you ask simply, is the true mean for population 1 greater than that for population 2, then you reject the null hypothesis.
This table below is a compilation of data from the Student t distribution. Anytime that a t-distribution is being used, a table such as this one can be consulted to perform calculations.This distribution is similar to the standard normal distribution, or bell curve, however the table is arranged differently than the table for the bell curve.The table below provides critical t-values for a.
The t distribution is generally perferred for using small samples to analyze the mean of a distribution (eg. use the t value vs. the z score). About this Website This t score calculator is part of a larger collection of tools we've assembled as a free replacement to paid statistical packages.
