Discusses ways in which psychological researchers can aggregate behavior over situations and occasions, thereby reducing variations that negatively affect replicability. (MK)

The costs of evaluation are affected by program characteristics and the extent to which it is important to be confident about proof and causality. They are also affected by decisions about issues, resources, evidence, data gathering, data analysis, and reporting. (CT)

This article is designed to help textbook selection committees and personnel make better choices of instructional materials. It outlines the types of information selectors will need about their own districts' curriculum and characteristics and presents a chart for design analysis of this data which can be used in textbook evaluation.

Measures of syntactic knowledge and reading achievement were obtained for 41 students in an adult basic education center. Adults reading at or below fourth-grade level showed significantly less knowledge of syntax than adults at higher levels, even though the language test involved neither reading nor writing. (Author/CT)

A procedure for approximating attained significance levels of exact conditional tests is proposed. The procedure utilizes a sampling from the null distribution of tables having the same marginal frequencies as the observed tables. (Author/JKS)

Two revisions of computer-interactive multidimensional scaling data selection procedures are presented. One revision--based on randomly ordering the list of stimuli--improves the estimates of the multidimensional scaling parameters and the other permits more efficient data designs. (Author/JKS)

An iterative procedure to obtain maximum likelihood estimates of latent structure analysis parameters is described. The procedure is defended against a critic (EJ 187 975) who contended that it would permit unacceptable estimates. (JKS)

Suggests that social science information services generally follow patterns set by science information services a decade or so earlier. Topics discussed include library research, the structure of communication and knowledge in the social sciences, communication patterns, shifts in methodology, and reassessment of achievements. (DB)

The effect of missing individuals upon the stability of the partition hierarchy yielded by the complete-link clustering technique was investigated. Empirical distributions of indices measuring the goodness-of-fit between partition hierarchies based on full and reduced sets of objects were obtained for data sets in which individuals were missing.…

While preserving the distinctive features of the case study, the case cluster method employs replicable sampling and, if desired, quantitative measurement procedures to complement qualitative analysis. It creates units of analysis that are based on theory and that have meaning for the actors and observers of the case. (Author/IRT)

A theoretical foundation is provided for a method of identifying those books in a library's stack that determine any given percentage of the current circulation. Basic components and requirements of the technique are described, and the theory is applied in an example that manipulates data from a university library. (Author/MBR)

Attempts to evaluate the hypothesis that rats are more hesitant to ingest novel-flavored substances while they are under the influence of a toxic agent than in the normal state. (Author/RK)

Questions the validity of a multiple-choice evaluation in which university students evaluated a lecture which had been cancelled. Comparison of this evaluation with evaluation of a film on sex and communication, which had been viewed by approximately 50 percent of the students, is offered. (Author/DB)

A total of 36 susceptible and 36 insusceptible subjects were tested to examine the effect of markedly contrasting styles of interpersonal orientation of the hypnotist on responsiveness in the hypnotic situation. (Editor)
