The purpose of this longitudinal study was to determine if there were changes in familism scores among a sample of African American and non-Hispanic White youths as they progressed through middle school, and if changes differed by race. Results indicated that African American subjects reported higher levels of familism than their non-Hispanic…

The Workshop on Integrating Federal Statistics on Children provided a forum for assessing strengths and shortcomings of existing and proposed federal statistical data sources for children and families. In particular, these data sources were assessed with respect to their capacity to fill the most pressing information needs of those who formulate,…

This paper reports the results of a Monte Carlo investigation of Type I errors in the single group repeated measures design where multiple measures are collected from each observational unit at each measurement occasion. The Type I error of three multivariate tests were examined. These were the doubly multivariate F test, the multivariate mixed…

The purpose of this study was to investigate the effectiveness of computer-aided instruction as compared with the traditional lecture method of cognitive learning of new curriculum materials. It was hypothesized that students instructed by the computer-aided instruction method would gain higher knowledge of the subject matter in terms of cognitive…

This 2-year study, which took a multidisciplinary approach to the problem of discovering principles for designing effective multimedia instruction, focused on the effects on instructional effectiveness of the discourse structure of instructional materials and the coordination of multiple instructional media. The task domain was a logic box said to…

This paper reviews multivariate hypothesis testing, interval estimation, and discriminant analysis procedures for an aptitude-treatment interaction (ATI) analysis and illustrates the procedures with data from a large experimental study of science education at the secondary school level. The treatment variable of interest is time allowed for study…

An experiment was designed to compare two alternative procedures for revising a preliminary version of an instructional program, one based on a subjective analysis of the program's behavioral goals, the other on an objective analysis of test data obtained from a trial of the unrevised program. Conforming to an experimental model, 20…

Unlike the past models guiding cross-cultural psychological research, a new paradigm facilitates multiple level investigations by incorporating both culture-specific (nested) and culture-general (crossed) independent variables within its partially-hierarchical framework. Based upon the generalizability analysis, this model generates sequential…

The VARAN (variance Analysis) program is an addition to a series of computer programs for multivariate analysis of variance. The development of VARAN exploits the full linear model. Analysis of variance, univariate and multivariate, is the program's main target. Correlation analysis of all types is available with printout in the vernacular of…

Alternative ways of analyzing data from Aptitude Treatment Interactions were examined over a two-year period. In light of past arguments the author maintains that the questions surrounding aggregation have been badly posed and that the customary methods of analysis were either incorrect or subject to misinterpretation. Therefore, the majority of…

Outlines the simple exercise of measuring the length of an object as a concrete paradigm of the entire process of making chemical measurements and treating the resulting data. Discusses the procedure, significant figures, measurement error, spurious data, rejection of results, precision and accuracy, and student responses. (TW)

Presents results from an exhaustive survey of Hertfordshire (England) primary schools which provides detailed information on microcomputer provision, classroom use, and headteachers' and teachers' aims and attitudes. An analysis of factors that influence microcomputer use is included. (Author/MBR)

A competency-based evaluation (skills test, minimum competence standard, attitude survey) conducted to measure effectiveness of large scale basic library skills workbook program showed that workbook instruction made statistically significant improvement in test scores, but failed to raise more than 53% of students to a minimum-competence level.…

This study compares the rates of single renewal and return from the home loan of English language books of The Ohio State University Libraries across subjects and patron status. The chi square test of equal proportionality is used to make comparisons between data sets. Ten sources are given. (Author/EJS)

A random sample of 113 members of the American Vocational Education Research Association (AVERA) was surveyed to obtain baseline information regarding AVERA members' perceptions of statistical significance tests. The Psychometrics Group Instrument was used to collect data from participants. Of those surveyed, 67% were male, 93% had earned a…
