SAFFORD, PHILIP L. – 1967
THE RELATIVE EFFECTIVENESS OF TASK SCORES VERSUS IQ AS PREDICTORS OF ACADEMIC ACHIEVEMENT WAS INVESTIGATED, AND THE CORRELATIONS BETWEEN TASK SCORES AND IQ RE-EXAMINED. SUBJECTS WERE 99 UPPER-MIDDLE CLASS ELEMENTARY SCHOOL CHILDREN WITH A MEAN STANFORD-BINET IQ OF 126 (SD EQUALS 19). THE INSTRUMENTS USED WERE DUNN'S OBJECT SORTING TASK (OST),…

Brown, Roscoe C., Jr.; Henderson, Edward H. – 1967
The document presents the findings of a multiple regression analysis and a factor analysis of variables used in the prediction of student performance after two years of participation in Project APEX. This project seeks to demonstrate that 24 disadvantaged students with college potential can succeed in a special university program. Subjects were…

Wilson, Barry; And Others – 1977
The Brain Wave Analyzer (BWA Ertl 02) was used to measure the brain potentials of 110 public school children. Resulting scores were correlated with concurrent measures of school achievement. Results indicate that certain brain wave scores have relatively low correlations with school achievement compared to traditional intelligence measures but may…

Einbecker, Polly Godwin – 1974
The purpose of this investigation was to determine the relationship between reading ability and academic performance of junior college freshman and to what degree a measure of reading ability could predict academic performance. The 313 Pensacola Junior College freshman for whom 1970 Reading Index Scores on the Florida Twelfth Grade Test were…

Tsai, Yung-mei; Perry, Floyd, Jr. – 1975
The study's purpose was to: (1) identify factors affecting college students' academic performance measured by college grade point average (GPA) and persistence identified by whether or not withdrawn from the university initially attended; and (2) compare these factors among Black, Mexican American, and Anglo students. Data were obtained from the…

Levin, Joel R.; Marascuilo, Leonard A. – 1971
Marascuilo and Levin's (1970) notion of Type IV errors is extended, with respect to the interpretation of interactions in analysis of variance (ANOVA) designs. To help clarity what an interaction is and what it is not, in terms of the ANOVA model, the following points are made: (i) interactions should be thought of as linear contrasts involving…

Morris, John D. – American Educational Research Journal, 1979
Computer-based Monte Carlo methods compared the predictive accuracy upon replication of regression of five complete and four incomplete factor score estimation methods. Prediction on incomplete factor scores showed better double cross-validated prediction accuracy than on complete scores. The unique unit-weighted factor score was superior among…

Ottenbacher, Kenneth J. – Journal of Special Education, 1990
The agreement between visual analysis and the results of the split-middle method of trend estimation was examined using a set of 24 stimulus graphs and 30 raters. Results revealed poor agreement between the two methods, and low sensitivity, specificity, and predictive ability for visual analysis in relation to statistical inferences. (JDD)

Hilton, N. Zoe; Harris, Grant T.; Rice, Marnie E. – Counseling Psychologist, 2006
In their meta-analysis of clinical versus statistical prediction models, Aegisdottir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians' experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest…

Ervin, Nancy S. – 1988
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…

Guinn, Nancy; And Others – 1977
A sample of 4,502 airmen assigned to the security police career field were administered a test battery consisting of biographical, attitudinal, and interest measures. Using a criterion of in/out of service after a minimum period of one year on the job, regression analyses were accomplished to determine the effectiveness of the predictor…

Disch, James G.; Morrow, James R., Jr. – 1979
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…

Smith, John E.; And Others
The purpose of this study was to construct and validate a self-rating scale which can be easily administered and quickly scored for discriminating between those high school students who will dropout and those who will not. A 34-item scale was constructed for subjects with a fifth grade reading level. This scale was administered to 113 high school…

McMorris, Robert F. – 1971
The extent of error likely to occur with each of several approximations for the standard deviation, internal consistency reliability, and the standard error of measurement is analyzed. Approximations were compared with exact statistics obtained on 85 different classroom tests constructed and administered by professors in a variety of fields. Means…
