Paper discusses the nature of the suppressor variable, constraints upon the degree of gain in predictability by the addition of a suppressor, and the distinct aims of prediction and of construct measurement. (Authors/MB)

The relative predictive validity of girls' and boys' success in algebra is examined. Eighth-grade students completed the Orleans-Hanna Algebra Prognosis Test. These prognosis test scores were correlated with grades that students subsequently earned in first-year algebra. Algebra grades of girls proved to be the more predictable. (Author/DWH)

The idea that validity should be considered a property of inferences, rather than of assessments, has developed slowly over the past century. In early writings about the validity of educational assessments, validity was defined as a property of an assessment. The most common definition was that an assessment was valid to the extent that it…

An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

This paper presents results of a study examining the relationship between the American Board of Surgery's In-Training Examination and its Qualifying Examination. 1982 Test scores on both examinations of 764 candidates in their fifth year of training as Chief Residents were analyzed. Descriptive statistics, correlations, and standard errors were…

Data presented in this study of the Academic Interest Measures (AIM) include score distributions for a national sample of high school juniors grouped by sex, ability, and curriculum (effects of socioeconomic status were found to be negligible); relationships between AIM and many other variables, such as ability test scores, students' ratings of…

This study was conducted to determine the usefulness of a general global reading test, a cloze test, and a vocabulary test as predictors of success, as well as the effects of an extended required study skills program on success and achievement, for students in mechanics programs at Keewatin Community College in Manitoba, Canada. The three criteria…

Data from the Canadian Test of English for Scholars and Trainees (CanTEST) are compared to data from the Test of English as a Foreign Language (TOEFL) to establish CanTEST as a valid admissions tool for English-as-a-Second Language college applicants. Data are taken from four groups of examinees who took both tests. (eight references) (LR)
