William Sealy Gosset (Student's t)

William Sealy Gosset was a British mathematician and statistician who, under the pseudonym "Student," developed the Student's t-test. This statistical method helps compare the averages of two small or uncertain sample groups to determine if they are significantly different. Gosset's work was vital for quality control and scientific research, especially when only limited data is available. His contribution allows researchers to make informed inferences about populations from small samples, improving decision-making across various fields.
