Chapter 2 starts with a brief summary of the contributions of Francis Galton and Karl Pearson to the development of statistics in the late 19th Century and early 20th Centuries. The authors blame Galton for keeping the study of statistics on the first rung of the ladder of causation and discouraging any discussion of causality in statistics. Causal analysis using path diagrams is then introduced through the explanations of the work of Sewall Wright. | Chapter 2 starts with a brief summary of the contributions of Francis Galton and Karl Pearson to the development of statistics in the late 19th Century and early 20th Centuries.
