THIS NOTE IS CONCERNED WITH IDEAS AND PROBLEMS INVOLVED IN CROSS-CLASSIFICATION OF OBSERVATIONS ON A GIVEN POPULATION, ESPECIALLY TWO-DIMENSIONAL CROSS-CLASSIFICATIONS. MAIN OBJECTIVES OF THE NOTE INCLUDE--(1) ESTABLISHMENT OF A CONCEPTUAL FRAMEWORK FOR CHARACTERIZATION AND COMPARISON OF CROSS-CLASSIFICATIONS, (2) DISCUSSION OF EXISTING METHODS…

Statistical data and analyses concerning student enrollment in New England institutions of higher education, 1973-1974, is presented. Data is divided to cover: (1) Enrollment in New England 1955-1973; (2) Enrollment Growth and Distribution Within the Six New England States; (3) Institutional Growth and Change in the Region 1955-1973; (4) Current…

This article describes a simple way to explain the limitations of statistics to scientists and students to avoid the publication of misleading conclusions. Biologists examine their results extremely critically and carefully choose the appropriate analytic methods depending on their scientific objectives. However, no such close attention is usually…

Quite often in data reduction, it is more meaningful and economical to select a subset of variables instead of reducing the dimensionality of the variable space with principal components analysis. The authors present a neglected method for variable selection called the BI-method (R. P. Bhargava & T. Ishizuka, 1981). It is a direct, simple method…

Since research conclusions derived from inappropriate statistical methodologies can lack accuracy, the article describes a technique appropriate to the heterogeneity of special needs groups in which subjects are assigned to fairly homogeneous subgroups. The technique is related to research in reading with this population. (DB)

Contradictary reports about almost everything are poured into almost everyone, constantly, by the media. (JH)

This paper defines an index of plan implementation and applies it to the 1960-70 educational plans of Latin American countries. Before the index is applied, variations in the value of the index are studied, with reference to the characteristics of the departments of educational planning, and the coordination of these departments with the central…

The data presented in this report call attention to inappropriate use of the Eigenroot criterion in factor work, a practice which has probably grown out of a theoretical focus on determining basic laws of behavior, rather than a practical emphasis on providing information that will be useful to college instructors and administrators. When…

Normative data for the students taking the Miller Analogies Test at the University of Wisconsin-Madison are reported. Separate norms are provided for U.W. students (N=366) and non-U.W. students (N=162). All students were tested in 1969 or 1970 with either Form M or Form L. (Author)

Presents the findings from a nationwide survey by the Educational Research Service, Inc. of principals on early childhood education. (MD)

Provides a mathematical model for comparing the infant mortality rates (IMRs) of different States to long-term trends. Presents separate analyses of white IMRs in 49 States and non-white IMRs in 30 States. Nine States had infant mortality trends less favorable than the national experience and 1981-83 rates more than 5% above the national average.…

The Modern Language Association has created a computerized database for the world's 3,024 periodicals on language and literature from which it can retrieve current information including: the number of periodicals in the field and the rate new ones are introduced, number of manuscripts submitted and published each year, etc. (MLW)

We consider power calculation in structural equation modeling with data missing completely at random (MCAR). Muth?n and Muth?n (2002) recently demonstrated how power calculations with data MCAR can be carried out by means of a Monte Carlo study. Here we show that the method of Satorra and Saris (1985), which is based on the nonnull distribution of…
