Explains two basic exploratory techniques for displaying and summarizing data--the stem and leaf diagram and the box and whiskers plot--and applies them to a data set consisting of federal allotments and state and local matching funds. One table, three figures, and seven sources are included. (Author/RBF)

Canonical correlation analysis is considered to be a general model for bivariate and multivariate statistical methods. Some problems involving assumptions and statistical tests for parameters exist for social science data. A resolution for these problems is presented by treating canonical correlation as a special case of linear structural…

This article examines simple and multiple regression analysis as forecasting tools, and details the process by which multiple regression analysis may be used to increase the accuracy of the technology forecast. (CT)

The Triangular Constant Method was designed for the measurement of discriminability between sensory stimuli. Its original model assumes a steady excitatory detection state. The purpose of this paper is to elaborate on the consequences of assuming a variable exicitatory state and to formulate the concomitant model. (Author)

Disagreements have arisen about the robustness of the t test in normal populations with unequal variances. Employing liberal but objective standards for assessing robustness, it is shown that the t test is not always robust to the assumption of equal population variances even when sample sizes are equal.

The importance of marriage timing for educational attainment is examined for a national sample of young men and women. Schooling obtained prior to marrying is distinguished from that afterward. Concludes that marrying early is detrimental to the educational attainments of women but of little or no consequence for men. (Author/DB)

Describes the results of a study designed to answer the questions of whether (1) the socialization of prospective physicians begins prior to the start of their formal training, and (2) the value shifts measured by the Survey of Interpersonal Values begin prior to entering medical school.

The grievance data analysis model discussed here provides postsecondary administrators with an effective aid for managing institutional policy problems, problem subunits within an institution, and faculty grievance processing. (Author/IRT)

Five prototypic issues derived from a dialectical perspective are proposed: relationism, evolving reciprocity, probabilism, timing, and the nonequivalent temporal metric. It is argued that these issues, while not changing the scientific method, have implications for specific procedures. (Author)

A jackknife-like procedure is developed for producing standard errors of estimate in maximum likelihood factor analysis. Unlike earlier methods based on information theory, the procedure developed is computationally feasible on larger problems. Examples are given to demonstrate the feasibility of the method. (Author/JKS)

A statistical analysis procedure is developed, based on the notion that many educational programs are dynamic interventions in natural growth processes, and is called value-added analysis. The theory of value-added analysis, and several applications are presented. (Author/JKS)

Hollingsworth recently showed a posttest contrast for analysis of variance situations that, for equal sample sizes, had several favorable qualities. However, for unequal sample sizes, the contrast fails to achieve status as a maximized contrast; thus, separate testing of the contrast is required. (Author/GSK)

Data evolving from processes which are developmental or hierarchical in nature are often analyzed by using latent class or latent structure models. A procedure for estimating such models when the model is not "identifiable" is presented. (JKS)

A study on the readability of publications of the Florida Cooperative Extension Service shows that most are written at the 12th-grade level, though the average Floridian reads at the sixth-grade level. The materials present a barrier to comprehension by limited-resource audiences in Florida. (JOW)

The model set forth in this article makes it possible to describe and judge an educational program (specifically, nursing) on the basis of data obtained through a specified inquiry process. It provides a systematic method for organizing various types of data and allows the examination of relationships among those data. (CT)
