摘要:Four measurements (providing 2 indices) were taken on the malar bones of 639 [male] and 71 [female] skulls representing 14 races. No clear sexual difference in shape was found. The left bones tended to be slightly larger than the right. Most of the mean measurements indicated clear racial differences, and the Eskimo type was found to diverge markedly from all others on account of its large size and unusual shape. The measurements should be a valuable aid in testing problems of racial classific...

摘要:This paper discusses some aspects of the conceptual model which the mathematical statistician introduces in bringing probability theory into play as a guide to practical action. In particular the conception of randomization is discussed and illustrated.

摘要:The material discussed consists of 850 [male] Eskimo skulls measured by Furst and Hansen and Hrdlika. They relate to populations extending from the extreme north-east of Asia to Greenland. Seven regional groups are distinguished and the coefficients of racial likeness between them are given. Four are found to be closely related to one another, while the Greenland and an early Alaskan series diverges from these in one direction and a Western Alaskan series diverges from them in another directio...

摘要:This paper is a contribution to statistical tests of significance for 2-variate problems. In particular it deals with testing the difference between 2 correlation-coefficients. To this end the above random-sample distribution is developed and the case where the 2 samples have been drawn from the same normal population is more closely examined. It is shown that under these conditions the probability integral is a finite weighted sum of incomplete [beta]-functions, the weights being complete [be...

摘要:Original measurements of 2 English and a native Australian (d1 and 9) and a Punjabi ([male] only) series of mandibles, comprising a total of 338 bones, are analysed. The technique used is that described in earlier papers in Biometrika, and estimates obtained of the accuracy with which the measurements were taken are discussed. Other topics dealt with are methods of sexing, sexual differences, variabilities, correlations and asymmetry. Special attention is paid to the coefficients of racial lik...

摘要:Lobster claw deformity occurred in 1 [male] of 12 siblings, lobster claw plus cleft palate and hare lip in a [female] the latter had 3 of 5 children affected with lobster claw and 1 [male] and 1 [female] of these had cleft palate and hare lip also. No history was found among the descendents of the first affected.

摘要:This vigorous paper is a defense of the method of moments for curve fitting as against the claims of R. A. Fisher''s method of maximum likelihood. It is, in large part, a criticism of R. S. Koshal''s Application of the method of maximum likelihood to the improvement of curves fitted by the method of moments (Journ. Roy. Statistical Soc. 96: p.303, 1933). In reply to the statement that Koshal''s paper gave evidence of the superiority of the likelihood method, Pearson says that the argument is i...

摘要:A table published by Maurice Fishberg, based on mean cephalic indices of Jews and Gentiles in the same districts in Russia gave: [sigma]J = 83.05 and oJ = 1.888.121; mG = 83.50 and [sigma]g[long dash]2.093,741, the correlation of the cephalic indices being 0.8365. Contrary to Boas'' contention, Pearson rules out the influence of environment on the index and attributes it to the fact that there is a very considerable amt. of Jewish-Gentile intermarriage. This is borne out by the fact that in Ge...

摘要:In 32 pedigrees 21 show continuous inheritance, 3 show discontinuous, and 7 show both. As epicanthus tends to disappear with advancing age, some of the apparently discontinuous cases probably were really continuous.

摘要:The mean distance at which diamond type can be read without glasses is significantly greater for the right eye than for the left. There is considerable probability that light eyes can see farther than dark and some evidence, but far from conclusive, that dark-haired persons can see farther than light-haired.
