Dr. David Salsburg used this famous anecdote as the book title, and elaborated the development of modern statistics by several stories. Each chapter contains one outstanding statistician and his/her contributions. Impressively, the whole book was linked by R.A. Fisher, K. Pearson, E. Pearson and J. Neyman, these exclusively distinguished statistician, which indicates their fame and masterpiece has great impact on not only statistics but also academia of science, even our daily life.
Probability defined by Aristotle, “improbable things will happen”. Later on, the probability and its theory have been established by many mathematician’s efforts. However, it is until 1820, the first probability distribution, error distribution, was described by Laplace, which is much closer to modern statistics. Karl Pearson described that any type of scientific scatter data might meet this distribution, and he named it as “skew distribution”. Further, he established the description with four parameters that are “mean, standard deviation, symmetry and kurtosis”. Pearson believed that if the sample size is large enough, the estimations of these four parameters would delineate their true values. Nevertheless, it is almost impossible for us to know the true values because we would never know the all data from the whole
