The following illustrates the same geometrically with a different (less extreme) value of the t-statistic, as we can see, there are two (symmetric) blue regions that together represent the corresponding probability, under the 2-sided t-test. Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these
