Sir Ronald Aylmer Fisher |
1890-1962 |
Sir Ronald Aylmer Fisher was born in London England February 17th, 1890. He received his Bachelor of Arts in Astronomy from Cambridge University in 1912. At the time, he studied the theory of errors.
During his readings on the theory of errors, Fisher investigated several statistical problems from interest. Most stemmed from his work in that theory. In 1919, he gave up teaching at the university to work as a biologist on the Rohemsted Agricultural Experiment Station.
Fisher contributed to both genetics and statistics. In statistics, he introduced randomization and the analysis of variance. In 1921 he introduced likelihood and maximum likelihood, functions used in the analysis of data. In 1922, Fisher developed a new definition of statistics, which included three fundamental problems it attempted to solve on data:
Fisher also developed methods for small samples and studied hypothesis testing. Fisher is considered a founder of modern statistics.
Fisher died in Adelaide Australia in July, 1962.
Some of his achievements include the following medals from the Royal Society in England:
