The 1990 National Household Survey on Drug Abuse is the 10th study in a series of national surveys to measure the prevalence of drug use among the American household population aged 12 and over. This report, which presents estimates of drug use prevalence for the civilian and noninstitutionalized population of the United States, is intended as a…

The two reports contained in this document are products of the 1988 National Household Survey on Drug Abuse, the ninth in a series of national surveys designed to measure the prevalence of drug use among the American household population aged 12 and over. The Main Findings report provides details of the National Household Survey methodology as…

It has been increasingly realized that (1) multivariate methods are essential in most quantitative studies (Fish, 1988; Thompson, 1992), and (2) all conventional parametric analytic methods are correlational and invoke least squares weights (e.g., the beta weights in regression) (Knapp, 1978; Thompson, 1991). The present paper reviews one very…

A study investigated the correlation between students' learning styles and their academic achievement on report cards and standardized tests. Subjects were 58 fifth-grade students in a suburban middle school. The "Learning Style Inventory" by Brown and Cooper was administered to this population, and students' academic averages and…

Aptitude test scores have been correlated with grades in twenty-six courses and with overall indices of academic performance, based on over 500 students attending a public high school. There is little evidence of differential validity for the major academic subject areas; instead, five tests (English Vocabulary, Graphoria, Silograms, Analytical…

Statistics used to estimate the population correlation ratio were reviewed and evaluated. The sampling distributions of Kelly's and Hays' statistics were studied empirically by computer simulation within the context of a three level one-way fixed effects analysis of variance design. (Author/RC)

The objectives of the study were to ascertain the effectiveness of seventh grade performance on a standardized achievement test and of selected items of life history information as predictors of the cumulative senior high school grade point average. (Author/KM)

It is a widely held belief that an anchor test used in equating should be a miniature version (or "minitest") of the tests to be equated; that is, the anchor test should be proportionally representative of the two tests in content and statistical characteristics. This paper examines the scientific foundation of this belief, especially…

This paper explores the relationship of developmental advising and frequency of faculty-student contact to college students' cognitive growth. The study involved freshmen at two metropolitan Atlanta (Georgia) women's colleges: Agnes Scott College and Brenau College. Brenau freshmen participate in a two-quarter seminar which includes academic…

To develop a taxonomy of Cross Examination Debate Association (CEDA) critics, a study associated professed judging philosophy and responses to survey questions with ballot behavior and elaborated judging profiles. Subjects were debate critics who judged rounds at CEDA tournaments in the Northeast during the Spring 1989 season. In all, 13 critics…

Research findings on effective teaching are being used to identify potential "master teachers." This paper discusses six problem areas with respect to using research results in this manner. The first problem area is the question of whether the concept of "master" is necessarily implied by the concept of "effectiveness." In effect, does knowledge…

A set of 150 experimental personality items was constructed for an alternate form of the word association personality worksample developed by the Johnson O'Connor Research Foundation. The items were intended to possess several semantic properties hypothesized to facilitate discrimination between objective and subjective examinees. Specifically,…

Methods of probability modeling to analyze rater agreement are described, emphasizing their basic similarities and viewing them as variants of a common methodology. Statistical techniques for analyzing agreement data are described to address questions such as how many opinions are required to make a medical diagnosis with necessary accuracy. Kappa…

The nature of the criterion (dependent) variable may play a useful role in structuring a list of classification/prediction problems. Such criteria are continuous in nature, binary dichotomous, or multichotomous. In this paper, discussion is limited to the continuous normally distributed criterion scenarios. For both cases, it is assumed that the…
