Excerpt

William Sealy Gosset first described the t-test in 1908, when he published his article under the pseudonym 'student' while working for a brewery. In simple terms, a Student's t-test is a ratio that quantifies how significant the difference is between the 'means' of 2 groups while considering their variance or distribution.
