What Are t-Values? T-tests are called t-tests because the test results are all based on t-values. T-values are an example of what statisticians call test statistics.

- An Introduction to t Tests | Definitions, Formula and Examples - ScribbrIn this formula, t is the t value, x 1 and x 2 are the means of the two groups being compared, s 2 is the pooled standard error of the two groups, and n 1 and n 2 are the number of observations in each of the groups.
- T Test Overview: How to Use & Examples - Statistics By JimWhat is a T Test? A t test is a statistical hypothesis test that assesses sample means to draw conclusions about population means. Frequently, analysts use a t test to determine whether the population means for two groups are different.
- What are T Values and P Values in Statistics? - MinitabWhen you perform a t-test, you're usually trying to find evidence of a significant difference between population means (2-sample t) or between the population mean and a hypothesized value (1-sample t). The t-value measures the size of the difference relative to the variation in your sample data.
