Henry Wilcoxon
Harry Frederick Wilcoxon (8 September 1905 – 6 March 1984), known as Henry Wilcoxon, was an actor born in Roseau, Dominica, British West Indies, and who was a leading man in many of Cecil B.

Wilcoxon Signed-rank Test
The Wilcoxon signed-rank test is a non-parametric statistical hypothesis test used either to test the location of a population based on a sample of data, or to compare the locations of two populations using two matched samples., p. 350 The one-sample version serves a purpose similar to that of the one-sample Student's ''t''-test. For two matched samples, it is a paired difference test like the paired Student's ''t''-test (also known as the "''t''-test for matched pairs" or "''t''-test for dependent samples"). The Wilcoxon test can be a good alternative to the ''t''-test when population means are not of interest; for example, when one wishes to test whether a population's median is nonzero, or whether there is a better than 50% chance that a sample from one population is greater than a sample from another population. History The test is named for Frank Wilcoxon (1892–1965) who, in a single paper, proposed both it and the rank-sum test for two independent samples. The test was p ...

Charles Wilcoxon
Charles "Charley" Wilcoxon was an American drum teacher and drum method book writer. He wrote several influential books on rudimental drumming that are still used by drum teachers today. He is a member of the Percussive Arts Society Hall of Fame. Bio Charles Wilcoxon was born November 26, 1894 in Coshocton, Ohio, or possibly Newark, Ohio.Sakal, Richard, ed. ''Modern Rudimental Swing Solos for the Advanced Drummer''. By Charley Wilcoxon. Ohio: Ludwig Music, 1979. He received his first drum in 1899 at the age of 5 and was taught basic music reading by his mother, a piano teacher. He began performing at the age of 8 in movie theaters around Coshocton. He started teaching at 12 and was touring at 14 with the vaudeville show "Spring Maid". Charles was a member of the touring orchestra for the D.W. Griffith movie “Intolerance.” From 1922 to 1933 he played at The Palace in Cleveland, as the house drummer. He then founded his own music store in the 1930s, where he lathed custom drum ...

Frank Wilcoxon
Frank Wilcoxon (2 September 1892 – 18 November 1965) was a chemist and statistician, known for the development of several statistical tests. Education and career Frank Wilcoxon was born to American parents on 2 September 1892 in County Cork, Ireland.Bradley, R.A. (1966) ''Obituary: Frank Wilcoxon.'' Biometrics 22(1): 192–194 He grew up in Catskill, New York, but received part of his education in England. In 1917, he graduated from Pennsylvania Military College with a B.Sc. After the First World War he entered graduate studies, first at Rutgers University, where he was awarded an M.S. in chemistry in 1921, and then at Cornell University, gaining a Ph.D. in physical chemistry in 1924. Wilcoxon entered a research career, working at the Boyce Thompson Institute for Plant Research from 1925 to 1941. He then moved to the Atlas Powder Company, where he designed and directed the Control Laboratory, before joining the American Cyanamid Company in 1943. During this time he develo ...

Non-parametric
Nonparametric statistics is the branch of statistics that is not based solely on parametrized families of probability distributions (common examples of parameters are the mean and variance). Nonparametric statistics is based on either being distribution-free or having a specified distribution but with the distribution's parameters unspecified. Nonparametric statistics includes both descriptive statistics and statistical inference. Nonparametric tests are often used when the assumptions of parametric tests are violated. Definitions The term "nonparametric statistics" has been imprecisely defined in the following two ways, among others: Applications and purpose Non-parametric methods are widely used for studying populations that take on a ranked order (such as movie reviews receiving one to four stars). The use of non-parametric methods may be necessary when data have a ranking but no clear numerical interpretation, such as when assessing preferences. In terms of levels of meas ...

Statistics
Statistics (from German language, German: ''wikt:Statistik#German, Statistik'', "description of a State (polity), state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of statistical survey, surveys and experimental design, experiments.Dodge, Y. (2006) ''The Oxford Dictionary of Statistical Terms'', Oxford University Press. When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey sample (statistics), samples. Representative sampling as ...
