The concepts of elevation, scatter, and shape are investigated as parameters in assessing the similarity among profiles of individuals. A computational strategy for differentiating the independent contribution of each parameter to more global indices of resemblance is presented. (Author/JKS)

Documents an experiment in the application of R. H. Atkin's methodology of Q-analysis in the field of television which demonstrates how it may be applied to program schedules. A theoretical discussion illustrates the relationships between the program-time interval backcloth and the viewing patterns it can support. (Author/VT)

The promise of time-series designs for educational research and evaluation is reviewed. Ten time-series designs are presented and discussed in the context of threats to internal and external validity. The advantages and disadvantages of various visual and statistical data-analysis techniques are presented. A bibliography is appended. (Author/RD)

Path analysis is a data analytic technique for estimating the strengths of hypothesized relationships among a group of variables for a particular sample. Strategies for the use of path analysis are discussed in detail in this extensive article. (JKS)

Data from a national sample of academic library directors were used to determine their educational attainment, previous professional experience, selection processes through internal or external channels, and whether male or female directors tend to be appointed through internal or external progression. (JAB)

A computer program which generates descriptions of conversational patterns of dyads based on sound-silence data is described. Input consists of talk/no-talk designations; output consists of descriptive matrices, histograms, and individual talk parameters. (Author/JKS)

A re-analysis of evaluation data concerning the Emergency School Aid Act shows that findings of the original evaluators are open to multiple interpretations. (JKS)

Commentary is presented on the evaluation of the Emergency School Aid Act and a review of that evaluation (TM 503 672). The commentary focuses on philosophical issues and the uses of several levels of observation in data analysis. (JKS)

Reexamines data from a study by Bayley and Schaefer and argues that no significant sex difference was demonstrated in their study. Points out that the male and female samples differed significantly with respect to both level of mother's education and children's IQ variance. (Author/JMB)

Findings of this study indicate that the degree of adequacy varies and identify three major needs: (1) prescriptive measures to ensure adequate subject analysis; (2) new subject heads to provide greater topic and race specificity; and (3) more research as the basis for improvement of present practices or the design of a new system. (Author/MBR)

A method for studying relationships among groups in terms of categorical data patterns is described. The procedure yields a dimensional representation of configural relationships among multiple groups and a quantitative scaling of categorical data patterns for use in subsequent assignment of new individuals to the groups. (Author/CTM)

EXPLORE is a flexible computer program for analyzing multiple data sets. The investigator has the option of focusing on the original variables, or of selecting a reduced rank solution where original variables are summarized by a principal components analysis. (Author/JKS)

The automatic interaction detector was applied as an evaluation tool to data normally collected by vocational-rehabilitation agencies. Demographic, service, and local agency variables were analyzed with mean weekly income at time of closure as the dependent variable. Recommendations for further research were made. (Author)

A relatively reliable and valid hierarchy of clusters of objects is plotted from the highest column entries, exclusively, of a matrix of interassociations between the objects. Having developed out of a loose definition of types, the method isolates both loose and highly definitive types, and all those in between. (Author/RC)

Discusses computer reduction and interpretation of chemical data in order to determine research trends. (SL)
