Note 865 — Chapter I · : THE HISTORICAL SCHOOL AND THE CONFLICT OF METHODS

We have not the necessary space in this volume to refer to the history of statistics. This science, though independent of political economy, is, however, such a powerful auxiliary that its progress has to some extent been parallel with the growth of economics. During the last twenty years the methods of interpreting statistics (we are speaking merely of observation) have been very considerably improved. The logical problems involved have been studied with much care, and the application of mathematics to these problems has proved very fruitful. No student of the social sciences can afford to neglect such mathematical theories as those of combination, correlation, degree of error, etc. The history of statistics, which contains many eminent names, from Quetelet to Karl Pearson, would certainly deserve a chapter in a book dealing with method, although there would be some risk of giving it too statistical a bias. We must rest content with referring the reader to Udny Yule’s Introduction to the Theory of Statistics, which constitutes what is perhaps the best recent introduction to the discussion concerning the method to be employed in this social science, and forms an indispensable complement to the study of the problems examined in this chapter.
