The Student's t test is one of the most commonly used statistical tests in the sciences. It is used to determine whether two groups of data are significantly different from each other. There are several synonyms that can be used to refer to this test, depending on the field of study. In engineering, it is sometimes called the t-test for equality of means. In psychology, it may be referred to as the t-test for independent samples or the t-test for dependent samples, depending on the nature of the data. Other synonyms for the Student's t test include the t-test for two populations, the t-distribution test, and the two-sample t-test.
