Donald Ransom Whitney
Donald Ransom Whitney (November 27, 1915 – August 16, 2007) was an American mathematician best known as a co-author of the Mann-Whitney U test. Born in East Cleveland, Ohio, he held his BA from Oberlin College, where he met his future wife Marian, MA in Mathematics from Princeton University, and a PhD in Mathematics from The Ohio State University. From 1942 to 1946, Whitney served in the U.S. Navy, then earned his PhD and joined the Mathematics faculty of Ohio State University. There he collaborated with Henry Mann and both soon published their article “On a test of whether one of two random variables is stochastically larger than the other”, Ann. Math. Stat. 18 (1947), 50-60, one of the most cited articles in statistics ever. Professor Whitney founded the Statistics Laboratory at The Ohio State University and later in 1970's served as Chairman of Statistics there. He was author or coauthor of three textbooks in mathematics and statistics and of many articles. He was a fell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mann–Whitney U Test
The Mann–Whitney U test (also called the Mann–Whitney–Wilcoxon (MWW/MWU), Wilcoxon rank-sum test, or Wilcoxon–Mann–Whitney test) is a nonparametric statistical test of the null hypothesis that randomly selected values ''X'' and ''Y'' from two populations have the same distribution. Nonparametric tests used on two ''dependent'' samples are the sign test and the Wilcoxon signed-rank test. Assumptions and formal statement of hypotheses Although Henry Mann and Donald Ransom Whitney developed the Mann–Whitney ''U'' test under the assumption of continuous responses with the alternative hypothesis being that one distribution is stochastically greater than the other, there are many other ways to formulate the null and alternative hypotheses such that the Mann–Whitney ''U'' test will give a valid test. A very general formulation is to assume that: # All the observations from both groups are independent of each other, # The responses are at least ordinal (i.e., one ...

East Cleveland, Ohio
East Cleveland is a city in Cuyahoga County, Ohio, United States. The population was 13,792 at the 2020 United States census, 2020 census. It is a suburb lying east and south of Cleveland and west of Cleveland Heights. History Historically East Cleveland was partially founded by Scottish immigrants, whose names can still be found in the city such as Shaw, McIlrath, and Eddy. East Cleveland incorporated as a village in 1895 and became a city in 1911. This charter included provisions for women's suffrage, which at the time was unheard of east of the Mississippi River. Before the charter passed, the city of Cleveland, Ohio, Cleveland unsuccessfully attempted to annex the emerging municipality in 1910 and again in 1916. East Cleveland is home to General Electric's historic Nela Park, the world's first industrial park. Nela Park, which was added to the National Register of Historic Places in 1975, continues to operate today as the functional headquarters for GE Lighting and is the c ...

Henry Mann
Henry Berthold Mann (27 October 1905, Vienna – 1 February 2000, Tucson) was a professor of mathematics and statistics at the Ohio State University. Mann proved the Schnirelmann-Landau conjecture in number theory, and as a result earned the 1946 Cole Prize. He and his student D. Ransom Whitney developed the ("Mann-Whitney") ''U''-statistic of nonparametric statistics. (The web-link is to a slightly updated edition of the biography.) Mann published the first mathematical book on the design of experiments: . Early life of a number theorist Born in Vienna, Austria-Hungary, to a Jewish family, Mann earned his Ph.D. degree in mathematics in 1935 from the University of Vienna under the supervision of Philipp Furtwängler. Mann immigrated to the United States in 1938, and lived in New York, supporting himself by tutoring students. In additive number theory, Mann proved the Schnirelmann–Landau conjecture on the asymptotic density of sumsets in 1942. By doing so he established Man ...
