study of the collection, organization, analysis, interpretation, and presentation of data
To understand God's thoughts we must study statistics, for these are the measure of His purpose. ~ Florence Nightingale

Statistics is a mathematical science pertaining to the collection, analysis, interpretation and presentation of data.


  • 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.

  • Essentially, all models are wrong, but some are useful.
    • Attributed to statistician, George E. P. Box quoted in (1987). Empirical Model-Building and Response Surfaces, p. 424,
  • Statistics has been the most successful information science
  • Those who ignore Statistics are condemned to reinvent it.
  • The rise of biometry in this 20th century, like that of geometry in the 3rd century before Christ, seems to mark out one of the great ages or critical periods in the advance of the human understanding.
  • Politicians use statistics like drunkards use lampposts: not for illumination, but for support.
  • 91.7 percent of all statistics are made-up on the spot.

  • Average a left-hander with a right-hander and what do you get?

  • The true foundation of theology is to ascertain the character of God. It is by the art of statistics that law in the social sphere can be ascertained and codified, and certain aspects of the character of God thereby revealed. The study of statistics is thus a religious service.
    • Attributed to Florence Nightingale by F.N. David in Games, Gods, and Gambling: A History of Probability and Statistical Ideas, 1962, page 103.
  • Numbers and stats bob in a sentimental slop, a swampy slurry of bits of hard data and buckets of mushy manipulation.
  • 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 chowty dar [chowkidar] (village watchman), who just puts down what he damn pleases.
  • Thomasina: If there is an equation for a curve like a bell, there must be an equation for one like a bluebell, and if a bluebell, why not a rose? Do we believe nature is written in numbers?
    Septimus: We do.
    Thomasina: Then why do your shapes describe only the shapes of manufacture?
    Septimus: I do not know.
    Thomasina: Armed thus, God could only make a cabinet.
  • 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. [HG Wells 1911, Mankind in the Making 2041]

      • 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].
  • 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!»")
