The '''students t-test''' is a method of testing hypotheses in statistics. Specifically, the test is a way to measure the significance of a difference of means between two distributions, such as an observed distribution compared to the [[Normal distribution]].

Often the '''students t-test''' is used when comparing the mean between two groups, even if the standard deviations of the two groups are unknown.
