Ronald Fisher Quotes
However, perhaps the main point is that you are under no obligation to analyse variance into its parts if it does not come apart easily, and its unwillingness to do so naturally indicates that one's line of approach is not very fruitful.
Berelson had done a major compendium of research and found that the high quality studies with very good data were usually done in studies or programs that were not very important, while the most important areas were usually informed by poorer data and less rigid studies. As an example he gave the extensive data that the defense department then had on the relative physical fitness prowess of the marines verses the other services, but had little or no data as to whether the marine was a better fighter, had better judgment in crises, was more skilled with weapons system of the time etc. The Education Department had great data on the performance of students on mathematics tests but almost none on how to teach mathematics.
Sir Ronald Aylmer Fisher FRS was a British statistician, geneticist, and academic. For his work in statistics, he has been described as "a genius who almost single-handedly created the foundations for modern statistical science" and "the single most important figure in 20th century statistics". In genetics, his work used mathematics to combine Mendelian genetics and natural selection; this contributed to the revival of Darwinism in the early 20th-century revision of the theory of evolution known as the modern synthesis. For his contributions to biology, Fisher has been called "the greatest of Darwin’s successors".
