Compares four closed-formula estimators (Burkett, Claudy, Rozeboom, Browne) and the omit-one method for estimating TRS, the true shrunken correlation (not to be confused with TR, the true multiple correlation). Recommendations are based on artificial populations with known TRS. (Author/SV)

Refutes Mauger and Kolmodin's (1975) conclusion (see EJ 133 651) that their data does not support the author's (1968) conclusion that senior college grades are much less predictable from entrance information than freshman grades. States that their conclusion was not supported by their data and that the design of their study would allow no outcome…

Earlier studies have suggested that higher education institutions could harness the predictive power of Learning Management System (LMS) data to develop reporting tools that identify at-risk students and allow for more timely pedagogical interventions. This paper confirms and extends this proposition by providing data from an international…

Two forms of Holland's Hexagon Model (circular order and circumplex structure) are proposed and evaluated to demonstrate a randomization test of hypothesized order relations and confirmatory factor analysis. The models and methods are illustrated with correlation matrices based on the Unisex Edition of the ACT Interest Inventory. (Author/SK)

Four commonly employed procedures were repeatedly applied to computer-simulated samples to provide comparative data pertaining to two questions: (a) which procedure can be expected to produce and equation that yields the most accurate predictions for the population, and (b) which procedure is most likely to identify the optimal set of independent…

In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. (Author)

One hundred culturally disadvantaged children were tested on culture-fair (Raven) and culturally biased (WISC) tests, and scores were correlated with academic achievement. (Author)

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

A method is presented to use school-level attributes in sample description and random assignment of schools to conditions in drug prevention programs. Utility of archival data was examined using multivariate canonical techniques, and it was found that a small set of data could predict observed variations in drug use. (SLD)

Describes an investigation which assessed predictive value of Iowa Test of Educational Development, Science Research Associates Inc.'s Computer Programming Aptitude Battery, and Wolfe Programming Aptitude Test for predicting secondary school students' success in computer science courses, to develop a prediction model, and to estimate mastery…

This study examined parental report as a source of information about toddlers' productive vocabulary in 105 low-income families living in either urban or rural communities. Parental report using the MacArthur Communicative Development Inventory-Short Form (CDI) at child age 2;0 was compared to concurrent spontaneous speech measures and…

An inquiry into methods of assessing the ability of non-English speaking children, conducted with the aim of devising new tests which can be used to assess the abilities of children from a different cultural background and with a poor knowledge of English, is discussed in this book. Cross-cultural tests which are essential in a multi-racial…

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…

This invitational conference was convened to report the principal findings of a six-year study of possible sources of bias in the prediction of job performance. The research was conducted jointly by Educational Testing Service and the U.S. Civil Service Commission, supported by the Ford Foundation. Data were gathered on test and job performance of…
