摘要：Mathematical derivation is given of the coefficient. Ax2 test, taking account of correlation of characters, would involve prohibitive labor. Coefficient of racial likeness agrees in general with common sense conclusions.

摘要：From the law of ancestral heredity the correlation between cousins is about 1/2, and the correlation of uncle and nephew about 70% of that of brothers. Pearson''s family records, however, show both cousinal and avuncular correlations of about 1/2 that of brothers, a result confirmed by Snow on mendelian grounds.

摘要：Data from 5600 males show that the correlation of head length and head breadth with reaction time is small,[long dash]-.034-.053 [plus or minus] .010. Cephalic index is not significantly correlated with reaction time. Means and standard deviations of head breadth and head length by age are given. It is suggested that size of head increases through adult life.

摘要：For small as well as large samples from a finite or infinite population the distribution of means is close to normal (except when the sampled population is extremely skew) and may be fitted satisfactorily by a Pearson curve. Under certain conditions approximately the same results are obtained by drawing from a finite or an infinite population. Distribution of a2 of small samples from an infinite population may be fitted with a Pearson curve by use of Tchouproff''s formulae for the moments. Cor...

摘要：The variate difference method may be used to separate the trend of an observed series from the residual chance component. Criteria are developed that the trend shall be representable by an nth order parabola.

摘要：In England and Scotland 4 cranial types are found, from late Neolithic times to present day: (a) extremely dolichocephalic Neolithic type, (b) brachycephalic Bronze Age type, (c) Iron Age type from which modern population descends, (d) Anglo-Saxon type, absorbed by native population without modifying the latter. Iron Age type and its descendants have extremely low skulls.

摘要：A general formula is derived for the probable error in large samples of the mode of Pearsonian frequency curves, with a discussion of the surface generated. The mode is usually less accurate than the mean, but in some [U-curves the antimode is more accurate. Tables of the probable error of the mode are given, as well as new tables of [beta]3 to [beta]6 for smaller differences of the arguments [beta]1 and [beta]2 than in Rhind''s tables.
