This is a critical review of the analytical models developed by the U.S. Army to predict training device effectiveness. The Simulation Systems Technical Area of the U.S. Army Research Institute for the Behavioral and Social Sciences performed the research. Special consideration is given to a family of models known collectively as TRAINVICE. These…

A survey gathering word lists from 40 locations in the Zambales Mountains of the Philippines, for statistical comparison, resulted in the definition of six distinct Negrito languages: Abelen, Magqanchi, Aberlen, Magqindi, Ambala, and Mabeken. With the use of a computer program, WORDSURV, designed for word list comparison, an Ayta language tree was…

The most appropriate statistical model for the small-scale (n<100) studies common in language testing research is the Rasch one-parameter logistic model. The Rasch model provides a wide range of options for conducting research, refining existing examinations, and developing tailored (computerized adaptive) language tests. Three investigations…

This study introduced a probabilistic model utilizing item response theory (IRT) for dealing with a variety of misconceptions. The model can be used for evaluating the transition behavior of error types, advancement of learning stages, or the stability and persistence of particular misconceptions. Moreover, it apparently can be used for relating…

The Educational Research Service annually reports an important statistical measure, the Composite Indicator of Changes in Average Salaries and Wages Paid by Public School Systems (CIC), which is designed to reflect overall changes in average salaries and wages paid by school systems in much the same way that the Dow Jones Average or the Standard…

All social science serves some agenda: social science research is a value-bound, value-determined, context-situated, and ideologically loaded enterprise. Each researcher makes choices in the following areas, whether tacitly, implicitly, or deliberately: (1) a paradigm choice, either conventional (rationalistic) or emerging (naturalistic); (2) the…

How accurately deltas (statistics measuring the difficulty of items) established by pre-test populations reflect deltas obtained from final form populations, and the consequent utility of pre-test deltas for constructing final (operational test) forms to meet developed statistical specifications were studied. Data were examined from five subject…

With the increasing number of part-time and adult students entering universities over the past several years, students who tend not to follow the traditional pattern of study, the task of accurate enrollment predictions has become increasingly difficult. The use of the Statistical Analysis System (SAS) software package to effectively track both…

This report addresses issues related to the extent and nature of misreporting of income and family size on applications for government-sponsored school meal benefits. Findings are reported from 741 in-home audits conducted with school meal program participants in nine school food authorities. In-home audits, which consisted of personal interviews…

The purpose of this research study was to assess item response model-test data fit using residuals. First, a comparison of raw and standardized residuals for describing model-test data fit was carried out. Second, hypotheses concerning the relationship between residual sizes and several item characteristics were studied. The analyses with…

The major finding of the Law-Related Education Evaluation Project report for Year 1 (1981), that law-related education courses can reduce juvenile delinquency, is of limited use to educational decision makers and could be misleading. The research design leaves much to be desired; however, that fact must be considered in light of the difficulty of…

A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x test score x item 1 x ... x item k contingency table. If the subgroup membership is unknown, the models are the incomplete-latent-class models of S. J. Haberman (1979). The…

A case study examined employee perceptions of the communication climate within a newspaper. Using qualitative and quantitative techniques, data were collected from 150 employees in 7 departments of a small newspaper organization, "Southwestern Newspapers". Results indicated that this newspaper can improve its communications climate by…

The use of loglinear latent class models to detect item bias was studied. Purposes of the study were to: (1) develop procedures for use in assessing item bias when the grouping variable with respect to which bias occurs is not observed; (2) develop bias detection procedures that relate to a conceptually different assessed trait--a categorical…

This report examines the determinants of the high level of infant mortality in Washington, D.C. Data were analyzed for 36,872 black resident single-delivery births occurring in the years 1980 through 1984, and 762 infant deaths occurring to these birth cohorts from 1980 to 1985. Findings were the following: (1) poor birthweight distribution among…
