I am a computer expert who loves a challenge. When I am not managing servers and fixing flaws, I write about it and other interesting things on various blogs.
9th Century - Al-Kindi was the first to use statistics to decipher encrypted messages and developed the first code breaking algorithm in the House of Wisdom in Baghdad, based on frequency analysis. He wrote a book entitled "Manuscript on Deciphering Cryptographic Messages", containing detailed discussions on statistics
1560s (published 1663) – Cardano's Liber de ludo aleae attempts to calculate probabilities of dice throws. He demonstrates the efficacy of defining odds as the ratio of favourable to unfavourable outcomes (which implies that the probability of an event is given by the ratio of favourable outcomes to the total number of possible outcomes ).
1577 – Bartolomé de Medina defends probabilism, the view that in ethics one may follow a probable opinion even if the opposite is more probable
17th century
1654 – Pascal and Fermat create the mathematical theory of probability,
1657 – Huygens's De ratiociniis in ludo aleae is the first book on mathematical probability,
1662 – Graunt's Natural and Political Observations Made upon the Bills of Mortality makes inferences from statistical data on deaths in London,
1666 - In Le Journal des Sçavans xxxi, August 2, 1666 (359-370(=364)) appears a review of the third edition (1665) of John Graunt's Observations on the Bills of Mortality. This review gives a summary of 'plusieurs reflexions curieuses', of which the second are Graunt's data on life expectancy. This review is used by Nicolaus Bernoulli in his De Usu Artis Conjectandi in Jure (1709).
1669 - Christiaan Huygens and his brother Lodewijk discuss between August and December that year Graunts mortality table (Graunt 1662, p. 62) in letters #1755
1693 – Halley prepares the first mortality tables statistically relating death rate to age,
1786 – Playfair's Commercial and Political Atlas introduces graphs and bar charts of data,
19th century
1801 – Gauss predicts the orbit of Ceres using a line of best fit
1805 – Adrien-Marie Legendre introduces the method of least squares for fitting a curve to a given set of observations,
1814 – Laplace's Essai philosophique sur les probabilités defends a definition of probabilities in terms of equally possible cases, introduces generating functions and Laplace transforms, uses conjugate priors for exponential families, proves an early version of the Bernstein–von Mises theorem on the asymptotic irrelevance of prior distributions on the limiting posterior distribution and the role of the Fisher information on asymptotically normal posterior modes.
1835 – Quetelet's Treatise on Man introduces social science statistics and the concept of the "average man",
1866 – Venn's Logic of Chance defends the frequency interpretation of probability.
1877–1883 – Charles Sanders Peirce outlines frequentist statistics, emphasizing the use of objective randomization in experiments and in sampling. Peirce also invented an optimally designed experiment for regression.
1933 – Andrey Nikolaevich Kolmogorov publishes his book Basic notions of the calculus of probability (Grundbegriffe der Wahrscheinlichkeitsrechnung) which contains an axiomatization of probability based on measure theory,
1935 – R. A. Fisher's Design of Experiments (1st ed),
1937 – Neyman introduces the concept of confidence interval in statistical testing,
1946 – Cox's theorem derives the axioms of probability from simple logical assumptions,
1948 – Shannon's Mathematical Theory of Communication defines capacity of communication channels in terms of probabilities,
