Summary (Statistics and the Housing Problem)Between now and 1960, the Netherlands will have to build about 900000 houses. Rents and prices being what they are at the present (index‐number of building costs = 350), realization of this program means expenditure of a vast amount of capital (7500000000 Guilders) which will not yield any interest.The houses necessary will not be built unless building costs can be cut to half their present value. This cannot be done whilst building houses in the old way but only by attacking the housing problem with the means of industrial mass production: standardization of a small number of types, industrial design, scientific preparation.Statistics can take an important part in realizing the housing program. Three aspects of applications of statistical methods are mentioned:a). Qualitative analysis of the types needed, by public opinion research. In this connection the problem of sample surveys arises.b). Measuring and analysing the productivity of labour by multiple correlation and analysis of variance.c). Controlling the dimensions of pre‐fabricated parts by the statistical approach to tolerances and statistical qual

摘要:

Summary (Sampling as a problem in industry).The elementary theory of sampling is discussed, especially that of small samples in massproduction. On the basis of some simple and very illustrative examples the various problems are considered and solved. It is shown that the manufacturer has to knout the quality of his products, their uniformity and how to maintain c.q. improve this uniformity. Statistical methods enable to control the production and give security as desired by the manufacturer and the customer as wel

摘要:

Summary (Three kinds of statistics in physics).A simplified derivation is given of the energy‐distribution of Maxwell‐Boltzmann, Bose‐Einstein and Fermi‐Dirac. The importance and the application of these laws are considered, and the fundamental hypotheses, on which they are based are mentioned.It is shown that only one sort of statistics is used, but that the statistical method is adapted in each case to the special physical properties of the particles, to which this method i

Summary (Uniformity trials)Uniformity trials can give information about the variation between individual observations. The number of blocks in the following trial, necessary to decide upon the significance between the main effects, can be derived from the value of the coefficient of variation (b.sigmax, %

摘要:

Summary (Statistical Aspects of Apparel Sizing).A description of the statistical principles underlying the design of a sizing system for apparel. The body measurements can be divided in primary and secundary measurements. The primary are independent variables, the secondary are highly correlated with the primary measurements. The choice of the primary measurements depends on the size of the tolerances, permitted in the other measurements and on the residual standard deviations after adaption of the regression equations. People are classified according to their primary measurements. The interval between two successive classes is two times the tolerance. The ideal class system is that in which as many people as possible fall within a limited number of classe
