Interpretation of emergent variables on the basis of structure coefficients (zero order correlations between original and emergent variables) is potentially very misleading and should be avoided in favor of interpretation on the basis of scoring coefficients. This is most apparent in multiple regression analysis and its special case, two-group…

It is recognized that parametric methods (e.g., t-tests, discriminant analysis, and methods based on analysis of variance) are special cases of canonical correlation analysis. In canonical correlation it has been argued that structure coefficients must be computed to correctly interpret results. It follows that structure coefficients may be useful…

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)

Five possible interpretations are given of very high correlations between scores on successively administered ability tests in a longitudinal sample of approximately 7,000 public school students tested in grades 5, 7, 9, and 11. At each of the four grades, students were given the appropriate level of the Sequential Test of Education Progress…

The Cognitive Abilities Test (CAT) provides separate ability estimates organized into three components; verbal, quantitative and non-verbal. There is no composite score. An analysis of scores obtained on the CAT and the Iowa Tests of Basic Skills (ITBS) by a sample student population indicated that discrepancies of twenty points or more among the…

The evidence used in condemning a test as racially biased is usually a validity coefficient for one racial group that is significantly different from that of another racial group. However, both variables in the calculation of a validity coefficient should be examined to determine where the bias lies. A study was conducted to investigate the…

External correlates of Minnesota Multiphasic Personality Inventory (MMPI) profile scales were investigated in a racially mixed urban sample of 247 adolescent psychiatric inpatients and outpatients (140 males and 107 females). Correlates included items completed by the patients' mothers. Gender plays a role as moderator of scale interpretation…

Research shows that there is a substantial degree of correlation between scores obtained on the Nelson-Denny Reading Test and the academic averages obtained by freshmen students at Harcum Junior College. This indicates that the reading test is a useful measuring instrument for predicting general levels of first-year academic achievement. (CK)

The purpose of this study was to determine the validity of the American College Test (ACT) in predicting academic achievement of students from an area which is culturally, economically, and educationally depressed. The population, chosen from 6 community colleges serving the Appalachian region of Kentucky, consisted of 1,127 full time (12 or more…

Reading test results and their interpretation are stressed because of their importance in student achievement. The Nelson-Denny Reading Test used at Harcum Junior College is a useful measuring instrument for predicting academic achievement, screening students, and diagnosing reading and learning problems. General hints for interpretation of the…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

The French and Guilford-Zimmerman measures of spatial orientation and spatial visualization factors are compared. Both approaches to measurement are described. A study to assess the two approaches is reported. Both tests were administered to 40 college sophomores in a classroom setting according to published instructions. Pearson product-moment…

The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and…

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…
