TATISTICAL concepts of one kind or another have been employed in S anthropology for over a century, but the emphasis has varied considerably among the constituent fields of anthropology. Physical anthropology has made the most use of statistics, while archeology, linguistics, and cultural anthropology have employed them much less frequently. If we compare anthropology as a whole to other social sciences, with which it is most commonly grouped, it is clear that economics, psychology, and sociology all use more statistics than anthropology.Why does anthropology differ in this respect from other social sciences and what can it say to justify its position? The most obtrusive fact which comes to mind is that anthropology covers a far greater range of subject matter, time, and space than other social sciences. Murdock (1951, p. 1) has recently conjectured that cultural anthropology surveys a range of human behavior perhaps a hundred times as great as history and a thousand times that of sociology. While his estimate seems high, it emphasizes the magnitude of the task anthropology has assumed and a t the same time the importance of this task to the sciences of human behavior. Another reason for lack of quantification, which applies mainly to cultural anthropology, is the lack of quantitative thinking on the part of the peoples we are studying. The culture of the United States today, with its money economy, weights and measures, and tax laws, provides the social scientist with perhaps a hundred times as many statistical facts as the ethnologist can obtain from his pre-literate and pre-industrial informants or from the amount of direct observation which they permit him to make.
