Issues relevant to the nature of attitudes are discussed. The reader is referred to works indexing a variety of existent attitude scales. The way in which one constructs, administers, scores, interprets, and presents findings of an original attitude measuring device is discussed comprehensively, and yet in a nontechnical fashion for…

A pattern-analytical technique, Similar Response Analysis (SRA), was developed, validated with contrived data, verified using previously reported data based on other pattern-analytical methods, and used successfully with "real" data. This technique orders subjects on the basis of the similarity of responses of adjacent individuals, not…

Two papers are presented. The first, "Report of the AISI Research Project on the Paintability of Galvanized Steel," was a project aimed at determining optimum procedures for painting bright-spangled galvanized sheet steel products using three classes of trade sales paints--metallic zinc-dust, portland cement-in-oil, and water base emulsion paints.…

Part-time indexers were trained according to a previously established training program. The performance of experienced indexers was compared to the performance of these index trainees. Several makes of microfiche readers were evaluated, particularly with regard to their use by indexers. One make offered the most advantages, and a number of these…

The Bibliography of Guidance and Guidance-Related Materials includes lsitings of the following: (1) audio visual materials, (2) books, and (3) booklet series. Books and booklet entries are annotated and are grouped under the following headings: (1) general education, (2) guidance, (3) psychology-mental health, (4) sociological grouping, (5)…

To differentiate student creativity by various tasks, the investigator used two classes with many minority-group students for whom certain admission requirements had been waived. In lieu of final exam, 17 experimental (Minority) and 28 control students received tests of creative thinking. Two forms were used, each with three separate figural…

Piaget's conception of cognitive development as the development of a set of skills resulting from interaction with the environment has had a great effect on contemporary educational theory and spurred the Educational Testing Service (ETS) to develop a set of written exercises based on this concept. Piaget's emphasis, however, was on concrete…

A classroom test is a work sample of all the behaviors the student must master in a given curriculum or part of the curriculum. Student performance on this sample enables the teacher to generalize concerning progress and mastery in the portion from which the sample is drawn. Each behavior to be mastered demands a suitable test or test items…

Techniques for detecting synergistic effects in analysis of variance designs are presented and discussed. These techniques make it possible to apply some kinds of theoretical insights to the data analysis phase of a study: either by seeking synergistic effects implied or predicted by theory, or by seeking evidence of synergies as alternative…

A study was made of the problem of representing the expectations of mean squares associated with analysis of variance sources of variation for experimental designs. These designs have a factorial structure over repeated measures or, for some other reason, have variates within a factorial design not all of which are mutually independent. A simple…

The Fisher Exact Probability Test considers independent groups and dichotomous criterion in a 2 by 2 (fourfold) contingency table. Fisher's test requires a determination of the combined probability of the observed frequency distribution and of the more extreme (in the same direction) frequency distributions. Typically, Fisher's test is for a small…

Since at least 1897, educational researchers have reported, with great frequency, "no significant differences" with respect to studies investigating the effects on educational outcomes of various treatments, suggesting that many educational variables are relatively impotent. A possible reason for at least many of the no-difference findings may lie…

The power of the t, expected normal scores, Mann-Whitney U, Tukey, a modified Mann-Whitney U, and an adaptive procedure were investigated when sampling from population models empirically developed from test score distributions. The models used were selected members of the beta family. This investigation was unique in that not only did the means of…

Researchers have long been aware that "pretest sensitization" is a potential threat to the external validity of experimental studies. Only recently, however, has it been suggested that "posttest sensitization" might also limit the generalizability of results. This latter phenomenon would exist to the extent that the effects of…

Multivariate models are demonstrated to analyze repeated measures profile and growth curve data when univariate or multivariate mixed model assumptions are not tenable. Standard mixed model tests are recovered from certain multivariate hypotheses. The procedures are illustrated using numerical examples. (Author/RC)
