William Sealy Gosset
(1876-1937)
• (1876-1937)
Lahir di Canterbury, Inggris, dari pasangan Agnes Sealy Vidal dan Kolonel
Frederic Gosset. Beliau belajar di Winchester College sebelum belajar kimia dan
matematika di New College, Oxford. Pada saat lulus pada tahun 1899, ia bergabung
dengan perusahaan pembuatan bir Dublin Arthur Guinness & Son. Disinilah ia
menggunakan ilmu statistiknya di bidang pembuatan bir dan seleksi varietas di
ladang gerst (semacam gandum untuk membuat bir). Gosset memperoleh ilmunya
dengan belajar, trial dan error dan juga menghabiskan waktunya antara 1906-7 di
laboratorium biometrik milik Karl Pearson. Gosset dan Pearson memiliki hubungan
yang baik, Pearson dibantu gosset dalam hal matematika dalam penulisan papernya.
Pearson dibantu dengan 1980 an paper tetapi tapi ia memiliki apresiasi yang kecil
terhadap pentingnya hal itu. Papernya ini sebagian besar membahas tentang
pembuat bir dengan metode sampel kecil , sementara biometrician yang biasanya
memiliki ratusan pengamatan dan melihat tidak ada urgensi dalam mengembangkan
metode-sampel kecil.
