In this article, we will explore some of the theory behind the one sample t test, assumptions of the test, interpretation and a worked example.

This article considers the problem of comparing two independent groups in terms of some measure of location. It is well known that with Student's two-independent-sample t test, the actual level of ...

Robustly comparing pairs of independent or related samples requires different approaches to the t-test.

Learn what a t-test is and discover the five standard assumptions made regarding the validity of sampling and data used in a t-test.

The standard t-test based on paired means is not valid if there is within-pairing variability. A generalized paired t-test is developed and a numerical example is given.

This short course provides an overview of statistical analyses useful for comparing the means for one or more samples. The statistical training will include the discussion of the one sample t-test, ...
