This study compared the object naming, object recognition, reading, and spelling abilities of 22 adults, half with written language difficulties and half without. Significant positive relationships were obtained between object naming ability and reading ability, object naming and spelling, and reading and spelling performance. Results suggest that…

An equation derived by W. A. Nicewander and J. M. Price relating statistical power to reliability of dependent variable measures when true score regression is homogeneous across treatment conditions is enhanced through overcoming the problem of directly estimating the squared linear correlation between true scores for X and Y. (SLD)

A technique is presented to transform incomplete categorical data into complete data by imputing appropriate scores into missing cells. A solution of the optimization problem is suggested, and relevant psychometric theory is discussed. The average correlation should be at least 0.50 before the method becomes practical. (SLD)

The degree of agreement between two raters rating several objects for a single characteristic can be expressed through an association coefficient, such as the Pearson product-moment correlation. How to select an appropriate association coefficient, and the desirable properties and uses of a class of such coefficients--the Euclidean…

Describes an ongoing project that is investigating the correlation between journal cost and citation ratings in the fields of political science and genetics. Previous studies that relate journal costs to other variables are reviewed; the conceptual framework is explained; limitations of the study are considered; and further research is suggested.…

Investigated correlations between two intelligence measures for exceptional children. Corrected correlations between the tests indicated differences with correlations reported in one manual. Relationships were generally higher than those reported elsewhere. Implications are discussed, especially those involving the use of correlations between…

Three heuristic methods of assessing the dimensionality of binary item pools were evaluated in a Monte Carlo investigation. The indices were based on (1) the local independence of unidimensional tests; (2) patterns of second-factor loadings derived from simplex theory; and (3) the shape of the curve of successive eigenvalues. (SLD)

A brief overview is provided of the Conger-Lipshitz approach to estimating the reliability of a profile or test battery. A computational example from a recent study shows how canonical reliability can be obtained through existing statistical software. (SLD)

Describes a study comparing the grades of community college students under and over 25 years of age in selected classes at 6 Virginia community colleges. Older students had higher grades on their first major exam and higher final grades in both transfer and development courses. Reviews prior research. (DMM)

Client satisfaction with outpatient psychotherapy in New Zealand was studied for 93 adult subjects who completed the Client Satisfaction Questionnaire. Clients reported a high degree of satisfaction, and there were positive correlations between satisfaction and symptom change on both client-related and therapist-related outcome measures. (SLD)

Use of parallel analysis (PA), a selection rule for the number-of-factors problem, is investigated from the viewpoint of permutation assessment through a Monte Carlo simulation. Results reveal advantages and limitations of PA. Tables of sample eigenvalues are included. (SLD)

Investigates whether the vocabulary of written comprehension questions is an independent factor in determining students' reading comprehension performance. Finds that academic vocabulary in comprehension questions significantly decreased question-answering performance. Computes simple, multiple, and semipartial correlations between vocabulary…

Finds that New Zealand students sampled were significantly less willing to communicate and experienced greater communication apprehension than U.S. students. Finds significant negative correlations for United States students between communication apprehension and humor variables (liking of humor, sensitivity to humor, and coping humor), whereas…

The relationship of teacher participation in Quality Circles to teacher satisfaction was examined for 64 elementary school teachers participating in 9 Quality Circle decision-making groups. Participation in the Quality Circles did not meet subjects' needs for achievement, recognition, or growth; and it did not increase job satisfaction. (SLD)

Describes study of undergraduate students in the United States and in China that was conducted to compare their attitudes toward computers, specifically computer anxiety. Attitude measures are discussed, statistical procedures for examining the invariance of constructs obtained from measurement scales are explained, and results indicate similar…
