“I am sending you a copy of Student’s Tables as you are the only man that’s ever likely to use them!”
William Sealy Gosset
William Sealy Gosset was born on June 13, 1876 in Canterbury, England an died on October 16, 1937 in Beaconsfield, England. He studied at Winchester College and then chemistry and mathematics at New College, Oxford.
He worked as a head brewer in Arthur Guiness & Son Brewery in Dublin. He examined ways how to statistically test the quality of ingredients - especially barley and hops. Unfortunately, the samples were characterized by high variability and small number of observations.
W. S. Gosset therefore developed his own z-test for small size of the statistical file. Because he was not allowed to publish under his own name, he used a pseudonym Student. The test therefore indicates Student’s z-test.
W. S. Gosset was apparently the first who introduced into the production practice statistical quality control. He influenced R. A. Fisher, Walter Shewhart and W. Edwards Deming and others.
* Gosset in a letter to R. A. Fisher who appreciated the importance of Gosset’s small-sample work. Student’s tables are now an integral part of the arsenal of statistical knowledge and methods.
