Although Fisherian testing does not use an explicit alternative, there is nothing to stop us from doing two Fisherian tests: a test of H0 : θ = 0 and then another test of H0 : θ = 2. The Fisherian tests both give perfectly reasonable results. The test for H0 : θ ...

Ronald Fisher
Sir Ronald Aylmer Fisher FRS (17 February 1890 – 29 July 1962), known as R.A. Fisher, was an English statistician, evolutionary biologist, mathematician, geneticist, and eugenicist. He began working at Rothamsted Research in 1919, where he developed the analysis of variance (ANOVA) to analyse its immense data from crop experiments since the 1840s, and established his reputation there in the following years as a biostatistician.Fisher is known as one of the three principal founders of population genetics, creating a mathematical and statistical basis for biology and uniting natural selection with Mendelian genetics, and as one of the chief architects of the modern evolutionary synthesis. He outlined Fisher's principle as well as the Fisherian runaway and sexy son hypothesis theories of sexual selection, and made important contributions to statistics, including the maximum likelihood, fiducial inference, and the derivation of various sampling distributions.Anders Hald called him ""a genius who almost single-handedly created the foundations for modern statistical science"", while Richard Dawkins named him ""the greatest biologist since Darwin. Not only was he the most original and constructive of the architects of the neo-Darwinian synthesis. Fisher also was the father of modern statistics and experimental design. He therefore could be said to have provided researchers in biology and medicine with their most important research tools, as well as with the modern version of biology's central theorem."" and Geoffrey Miller said of him ""To biologists, he was an architect of the ""modern synthesis"" that used mathematical models to integrate Mendelian genetics with Darwin's selection theories. To psychologists, Fisher was the inventor of various statistical tests that are still supposed to be used whenever possible in psychology journals. To farmers, Fisher was the founder of experimental agricultural research, saving millions from starvation through rational crop breeding programs.""
