## QuotesEdit

- In the 1930s English statistical theory was beginning to travel, with contributions from, amongst others, Hotelling and Snedecor in America and Darmois in France, but its home was still in England where there were four important centres: University College London, Rothamsted Experimental Station, Edinburgh University and Cambridge University with University College and Rothamsted far in the lead. Although Cambridge University was slow to adopt modern statistical theory, Cambridge men–Karl Pearson, Edmund Whittaker and Ronald Fisher–had put the other places on the statistical map. University College was the most established centre and its importance went back to 1893 when Karl Pearson, the professor of applied mathematics, first collaborated with Raphael Weldon, the professor of zoology on a subject they called “biometry.” There was a second surge in the “English statistical school” associated with R. A. Fisher who went to work at Rothamsted in 1919.

- I wish that people would be persuaded that psychological experiments, especially those on the complex functions, are not improved (by large studies); the statistical method gives only mediocre results; some recent examples demonstrate that. The American authors, who love to do things big, often publish experiments that have been conducted on hundreds and thousands of people; they instinctively obey the prejudice that the persuasiveness of a work is proportional to the number of observations. This is only an illusion.

**All models are wrong, but some are useful**

- Statisticians, like artists, have the bad habit of falling in love with their models.
- Attributed to statistician, George E. P. Box

- ...the statistician knows...that in nature there never was a normal distribution, there never was a straight line, yet with normal and linear assumptions, known to be false, he can often derive results which match, to a useful approximation, those found in the real world.

- briefly, and in its most concrete form, the object of statistical methods is the reduction of data. A quantity of data, which usually by its mere bulk is incapable of entering the mind, is to be replaced by relatively few quantities which shall adequately represent the whole, or which, in other words, shall contain as much as possible, ideally the whole, of the relevant information contained in the original data.

- According to a University College London study (2014), 40% of women surveyed with severe mental illness had suffered rape or attempted rape in adulthood, and 53% of those had attempted suicide as a result. In the general population, 7% of women had been victims of rape or attempted rape, of whom 3% had attempted suicide. If these statistics don't sound accurate to you, your hesitation or disbelief supports another reality about rape research: Because so many individuals who survive a rape may not report a rape (for a multitude of reasons), statistics have limited meaning.

- Although its evolution in the United States differed markedly from that of applied mathematics, statistics, too, benefited from the presence of the emigres and from the overall war effort. After a protracted period of professional differentiation from the social scientists and from the social sciences, mathematical statisticians had formed their own society, the Institute of Mathematical Statistics (IMS), in 1935. By 1938, the IMS had also taken over responsibility for the
*Annals of Mathematical Statistics*, a journal that had been founded in 1929 to serve the needs of the more mathematically and theoretically inclined statistical practitioners. Thus, when refugees like Neyman, William Feller, Mark Kac, and Abraham Wald took up positions in the United States at Berkeley, Brown, Cornell, and Columbia, respectively, they were able to participate in a young, but viable, community of mathematical statisticians.- Karen Hunger Parshall, "Perspectives on American Mathematics",

- The individual source of the statistics may easily be the weakest link. Harold Cox tells a story of his life as a young man in India. He quoted some statistics to a Judge, an Englishman, and a very good fellow. His friend said, Cox, when you are a bit older, you will not quote Indian statistics with that assurance. The Government are very keen on amassing statistics—they collect them, add them, raise them to the nth power, take the cube root and prepare wonderful diagrams. But what you must never forget is that every one of those figures comes in the first instance from the

- The death of one man is a tragedy, the death of millions is a statistic.
*Variants*: One death is a tragedy. A million deaths is just a statistic.

A single death is a tragedy; a million deaths is a statistic.

When one dies, it is a tragedy. When a million die, it is a statistic.- This quotation may originate from "Französischer Witz" (1925) by Kurt Tucholsky: "Darauf sagt ein Diplomat vom Quai d'Orsay: «Der Krieg? Ich kann das nicht so schrecklich finden! Der Tod eines Menschen: das ist eine Katastrophe. Hunderttausend Tote: das ist eine Statistik!»" ("To which a Quai d'Orsay diplomat replies: «The war? I can't find it so terrible! The death of one man: that is a catastrophe. One hundred thousand deaths: that is a statistic!»")

**Statistical thinking will one day be as necessary for efficient citizenship as the ability to read or write.**- Attributed to H. G. Wells by Darrell Huff in
*How to Lie with Statistics*(1954), epigraph - The actual quote referenced mathematics in general rather than statistics:
- The great body of physical science, a great deal of the essential fact of financial science, and endless social and political problems are only accessible and only thinkable to those who have had a sound training in mathematical analysis, and the time may not be very remote when it will be understood that for complete initiation as an efficient citizen of one of the new great complex world-wide States that are now developing, it is as necessary to be able to compute, to think in averages and maxima and minima, as it is now to be able to read and write.

*Historia Mathematica***6**(1): 30-33. DOI:10.1016/0315-0860(79)90101-0. - According to Tankard: It might be argued that statistics and mathematics were closely related in Wells' mind, and that when he wrote this passage he was to some extent thinking of procedures we would now regard as statistics. That is conjecture, however. Earlier sections of the paragraph deal with arithmetic and geometry, and its literal topic is mathematics. It doesn't contain the word "statistics " even though the term was clearly in use at the time of Well:' writing [Yule 19051].
