摘要：The exact method here derived is applied to samples of n from a rectangular and a straight line universe and to samples of 3 from a normal universe. Comparing the latter with E. S. Pearson''s approximate table (Biometrika 24 416) the approximation is found satisfactory.

摘要：Methods of evaluating the likelihood for small samples are developed. In this way analysis of small samples subjected to different treatments aids in the planning of further research.

摘要：The standard error of the mid-point between the quartiles, that of an estimate (E s) of the population standard deviation obtained from the distance between a quartile and the median, and the correlation between quartiles and median are derived. A more reliable estimate of the population mean is obtained from the midquartile point than from the median, though both estimates have a larger standard error than the sample mean. E 3 has a large standard error and is far from normally distributed.

摘要：Distributions of brain weight, stature, and vital capacity for younger and older groups are compared by the X2 method. It is probably better to use the most likely parent population than that obtained from the combined samples. From the ratios or the differences of the x for men and women, can be determined the probability that the shrinkage in the 2 sexes depends on the same causes.

摘要：Measurements were taken by R. Martin''s technique on living subjects. The northern Albanians are differentiated from the southern. Both have small and brachycephalic heads but the southern Albanians are smaller and more brachycephalic than the northern. This is probably not due to artificial deformation. Type contours are given.

摘要：Measurements, biometric constants and type contours are given for 255 adult skulls. The [male] and [female] series are probably of the same racial type. The [male][male] are more variable than the [female][female]. The population is more variable than some Dynastic Egyptian populations, but as homogeneous as most for which cranial samples are available. The type is distinctly negroid and the order of closure of sutures, % of metopism and other anomalies are intermediate between Negroes and Eur...

摘要：The correction of an error in a previous paper[long dash](See B. A. 8: entry 17283). It is not true that a parent population with marginal frequencies equal to those of the sample will give a minimum value of o2. The equations for determining these values have not been solved in the general case but in the special cases of fourfold and 2 X n-fold tables the minimum o2 differs little from that obtained by equating the marginal totals of the parent population and the sample.

摘要：On the basis of the Coefficient of Racial Likeness the skulls are more closely related to the English Bronze Age and Hythe skulls than to the Anglo-Saxon and are still closer to Etruscan skulls. Archeological evidence suggests the 5th or 6th century A.D. for the date of the burials. A broad-headed element derived largely from the Bronze Age people may have persisted in the locality or the population may have descended from a Roman colony with a large Central European element. The mandibles res...

摘要：The distribution is a sym-metrical curve having finite ordinates at the termini and an infinitely distant cusp on the axis of symmetry. This cannot be approximated to by a Pearson type curve. A sampling experiment suggests that for a rectangular universe the distribution is the same as for a normal.[long dash].
