Research the following about William Gossett:
1. Who was he?
William Sealy Gosset was the eldest son of Colonel Frederic Gosset, RE Born in Canterburyin 1876 and died on October 16, 1937.He was educated at Winchester, where he taught later, and at New College, Oxford where he studied chemistry and mathematics. In 1899 work began in thefermentation department brewery of Messrs. Guinness in Dublin.
Its main tool with which he began his studies were the books "Theory of errors of observations" of GBAiry and "least squares method" of M.Merriman. It is known that already in 1903 he calculated the probable error.
Employed by the brewer Guinness in Dublin in 1906 was sent by the company to work with K. Pearson at University CollegeLondon, where he conducted his major contributions to statistics, released under the pseudonym Student.
Gosset was a friend of both Pearson and Fisher, a great achievement, as both professed anintense mutual contempt. Gosset was a modest man who cut an admirer with the comment "Fisher would have discovered it anyway."
2. Why is he important in Statistics?
So Gosset developed the theoryhimself. In a now famous 1908 paper, The Probable Error of a Mean, he noted that s is an erratic estimator of s when n is small; hence, customary measures of the precision of estimates were invalidfor small samples and unknown s. His paper presented the sampling distribution of a statistic now known as Student's t and introduced small-sample estimation by means of the t-distribution family.It is difficult to overestimate the importance of this achievement.
All but one of Gosset's numerous papers were published under the pseudonym "Student" to protect the advances in his firm'squality control from nosy competitors.
