Two coefficients are proposed for measuring the
extent of overlap in distributions as a direct function of the
variance between the arithmetic means (»disco« and »odisco
«). They are designed to answer such questions as: »Given
the value of a numerical variable x, to which population
should an individual be assigned so that minimum error
would be incurred?« This is just the reverse of the question
addressed by ANOVA. These coefficients are shown to be
analytic in x and they are related to. Pearson's eta and
Fisher's F. Extensions of these coefficients (designed for
univariate, one way discrimination) to k-way and multivariate
discriminant analysis and measurement of »interaction
« are suggested.

El sociólogo debe ser muy prudente en el uso de conceptos estadísticos. La estadística matemática y la sociológica emplean términos similares pero que poseen diferentes significados. Un término de esta clase es ?probabilidad?. Para el matemático, semejante concepto no encierra ningún equívoco: expresa la certeza que implica la inclusión de un item en un modelo matemático. Sin embargo, el empleo de dicho término por parte de los sociólogos admite ciertos significados equívocos. Se presenta y se somete a discusión seis problemas aún irresueltos de estadística inferencial, y cincuenta sentidos distintos en que el empleo sociológico del concepto de ?probabilidad? difiere de su uso en la ciencia matemática

By use of a mapping sentence, a universe of observations is defined for soc problem indicators. Emphasis is placed on the concept of problem in order to distinguish such an observation from other observations of soc behavior. Similarly, a more detailed mapping sentence is presented for observations of data to guide policy formation of gov ministries. illustrations are given from the Continuing Survey conducted in Israel. A distinction is made between 'core' items & specific items. These considerations hold for data obtained from instit's or from individuals, whether the data be primary or secondary. uA.

By use of a mapping sentence, a universe of observations is defined for social problem indicators. Emphasis is made on the concept of "problem" in order to distinguish such an observation from other observations of social behavior. Similarly, a more detailed mapping sentence is presented for observations of data to guide policy formation of government ministries. Illustrations are given from the Continuing Survey conducted in Israel. Distinction is made between "core" items and specific items. These considerations hold for data obtained from institutions or from individuals, whether the data be primary or secondary.

Recent experience and theoretical advances have made possible considerable improvement in the measurement and analysis of opinions, attitudes, & beliefs. 7 methodological fronts are important at present, all bound together by the overall concepts of `structure', and 'deviation' from the structure. These are: (1) principle components of scalable attitudes, (2) image analysis, (3) the theory of facets, (4) the 'radex' approach to factor analysis, (5) the reliability of sums, (6) the theory of nedular structures, & (7) a metatheory for the analysis of social sequences. Each of these is discussed briefly and a 31 item bibliog is attached. K. Geiger.
