• The mathematics of intelligence. I. The sampling errors in the theory of a generalised factor. AI翻译
  作者：Pearson, K; Moul, M
  摘要：An analysis of Spearman and Holzinger''s work on the sampling errors of tetrads. The authors conclude that Spearman and Holzinger''s approximate formulae lead to serious errors, that the distribution of tetrads is not likely to follow a normal curve, and that the hypothesis of a general factor in intelligence is not proved.
• Goitre in adolescence; An anthropometric study of the relation between the size of the thyroid gland and physical and mental development. AI翻译
  作者：Stocks, P; Stocks, AV; Karn, MN
  摘要：The best index of the size of the thyroid is its maximum breadth; the circumference or diam. of the neck is of little value, and estimation by visual judgment is subject to large personal equations. The frequency of goiter increases until about 13-14 yrs. in boys, about 17-18 in girls, and then decreases. Where goiter is not endemic the thyroid grows very little, as compared with other parts of the body, from 101/2 to 131/2 yrs. In girls this is followed by rapid growth between 131/2 and 15 yr...

• Determination of the cranial capacity of the Negro from measurements on the skull or the living head. AI翻译

  摘要：Regression formulas for estimating cranial capacity from length, breadth, and auricular height.
• On partial multiple correlation coefficients in a universe of manifold characteristics. AI翻译
  作者：Tappan, M
  摘要：The partial multiple correlation coefficient, R0.123...nl uvw 1, is defined as the multiple correlation coefficient of the character 0 on the characters 1, 2, 3 [center dot] [center dot] [center dot] n in a universe in which the characters u, v, w [center dot] [center dot] [center dot] are constant. The properties of the coefficient are derived.
• Multiple and partial correlation coefficients in the case of an n-fold variate system. AI翻译

• A study of the Badarian crania recently excavated by the British School of Archaeology in Egypt. AI翻译
  作者：Stoessiger, BN
  摘要：A biometric study, with type contours, of Predynastic Egyptian skulls, probably the most ancient yet discovered. These closely resemble the Dravidians of India and Veddahs of Ceylon.
• On the coefficient of racial likeness AI翻译
  作者：Pearson, K
  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.
• On the skull and portraits of George!Buchanan AI翻译
