John Student (William Gosset)

John Student is a pseudonym used by British statistician William Gosset. He developed the "Student's t-test," a statistical method to determine if there are significant differences between the means of small sample groups. This is particularly useful when data is limited and helps researchers make inferences about larger populations. Gosset worked for the Guinness Brewery, where he aimed to improve quality control. His contributions have had a lasting impact on statistics, particularly in fields such as medicine and social sciences, aiding in hypothesis testing and data analysis.
