摘要: Abstract There are two motivations commonly ascribed to historical actors for taking up statistics: reduce complicated data a mean value (e.g., Quetelet), and take account of diversity Galton). Different will, it is assumed, lead different methodological decisions in the practice statistical sciences. Karl Pearson W. F. R. Weldon generally seen as following directly Galton’s footsteps. I argue related theses light this standard interpretation, based on reading several sources which Weldon, independently Pearson, reflects his own motivations. First, while does approach statistics from “Galtonian” perspective, he is, consistent with positivist philosophy science, utilizing simplify highly variable biology. other hand, brought by rich empiricism desire preserve biological data. Secondly, we have here counterexample claim that divergence motivation will corresponding separation methodology. despite embracing biometry reasons, settled precisely same set tools investigation evolution.
