This study examines how GRE scores can be used to better understand Education doctoral candidates' methodology choices for the dissertation as well as their persistence behaviors. Candidates' of one online doctoral education program were examined. Results of a MANOVA suggested that there is no difference in GRE scores based on doctoral candidates'…

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)

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…

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)

Assessed whether accounting for variables in the scoring of the Social Readjustment Rating Scale (SRRS) would improve the predictive validity of the inventory. Results from 107 sets of questionnaires showed that income and level of education are significant predictors of the capacity to cope with stress. (JAC)

The authors of "Differential Validity: Ethnic Group as a Moderator in Predicting Job Performance" (EJ 100 533) replied to criticism of their article by Wayne K. Kirchner (AA 521 804). (RK)

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

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)

Argues that the complex human behavior studied by educational researchers is by its nature unpredictable if not indeterminate. Concludes that research should focus on descriptions and interpretations of educational phenomena and not on the prediction and control of educational outcomes. (FMW)

A study examined the validity of using questions concerning retirement expectations in large-scale micro surveys. A simple static labor supply model that considered wages, hours worked, and health data was developed for this purpose. Next, the model was implemented using data from the National Longitudinal Survey (NLS) on the Labor Market…

The use of various physiological tests and measurements accurately predicts the performance ratings of female athletes. A study involving 180 female intercollegiate volleyball players, 142 female intercollegiate basketball players, and 115 female college-age nonathletes yielded a set of statistical differentials concerning arm length, lean weight…

Statistical validation is reported for the Child Care Perceiver Interview instrument, used in employing residential child care workers. Results indicate that the interview is effective in predicting job performance in group care settings and is acceptable in meeting Equal Employment Opportunity requirements. (Author/BB)

The utility of employing teacher reports about characteristics of students and their parents to assess family economic status was investigated using multiple regression analyses. The accuracy of teacher reports about parents' educational background was also explored, in addition to the effect of replacing missing data with logical, mean, or modal…

The Bean and Metzner Nontraditional Undergraduate Student Attrition Model appeared to be a good model to address community college student attrition because it takes into account the environmental variables that colleges must consider to enhance persistence. A study was conducted to determine how well the Bean and Metzner Model fit with community…
