Using a Monte Carlo simulation, a bootstrap procedure was evaluated for setting a confidence interval on the unrestricted population correlation (rho) assuming various degrees of incomplete truncation on the predictor. Sample size was the most important factor in determining accuracy and stability. Sample size should be at least 50. (SLD)

Compares coverage of five subjects in eight daily newspapers, employing both factor analysis and Pearson correlations. Computes correlation coefficients among newspapers by using (1) size of individual stories as items; and (2) space measurements by categories. Finds that different ways of coding the same raw data produced different results. (SR)

Investigates whether cognitive skills training influences college students' calibration of comprehension. Finds a significant correlation between students' judgments of their comprehension and performance on an objective comprehension test. Suggests that brief cognitive skills training can temporarily alter "normal" calibration of comprehension.…

Examines the relationship among four dimensions of patient satisfaction with physician care and nonverbal immediacy. Finds a significant positive correlation between nonverbal immediacy and overall patient satisfaction, with the strongest correlation to the attention/respect factor. (SR)

Eight-seven adult outpatients in Edinburgh (Scotland) were tested with the Wechsler Adult Intelligence Scale--Revised (WAIS-R) and a test of visual inspection time (IT). Factor analysis confirms that IT correlates more strongly with performance than with verbal intelligence quotient (IQ) scores. Implications for the study of IT and mental tests…

Examines the changes in dialect usage and the predictive relationship between dialect usage and reading achievement, controlling for differences in the acquisition of language forms common across dialects. Suggests that dialect usage might be a distinguishing variable between average and poor readers. Finds that correlations do not support the…

Discusses the intellectual structure of the sciences and describes a study that was conducted to test the usefulness of author cocitation analysis for empirically deriving groupings of intellectual leaders in the field of sociology. Results are contrasted with traditional subjective methods of codification of a field. (35 references) (LRW)

Discussion of models for library circulation data highlights a new statistical prediction model that creates a flexible regression curve. Linear graphs that result from previous models are discussed, bivariate discrete distributions are explained, and graphs that show library circulation for one year at a time are presented. (nine references) (LRW)

Investigates document ranking methods in thesaurus-based Boolean information retrieval systems and proposes a new thesaurus-based ranking algorithm called the Extended Relevance algorithm. Performance comparisons are made between the Extended Relevance algorithm and previous thesaurus-based ranking algorithms. (Contains 20 references.) (LRW)

The adequacy of multidimensional trait and item parameters using multidimensional item response theory analysis was studied through simulation using different degrees of correlation between two trait dimensions and the existence of a restricted trait on the second dimension. Conditions allowing adequate recovery of trait and item parameters are…

It is argued that the relative scoring method used to score the Ways of Coping Checklist introduces an artifact that confounds multivariate analyses and ignores the individual's general reactivity to the problem. Multivariate analysis is shown to suggest an intricate structural relationship between components of coping and depression. (SLD)

Use of linear combinations of Fisher's "z" transformations as a combined test for the common correlation parameter based on "k" independent sample correlations has been previously studied. This article considers additional "z" additive properties and methods of combining independent studies when planning the number of…

Investigates whether three cognitive components of language proficiency--metalinguistic awareness of symbol, syntax, and ambiguity--are associated with students' success in learning algebraic notation. Reports that very few students with low metalinguistic awareness scores achieved high algebra scores in a total sample of more than 1500 students.…

Models the relationship between a variety of Schools and Staffing Survey (SASS) (National Center for Education Statistics) school-level data and average student assessment scores. Findings demonstrate the potential value of combining SASS with school-level assessment data as well as some limitations of the restricted set of analyses reported.…

Explores whether indirect measures of memory are associated with age. Results, based on 30 younger and 30 older adults, suggest that direct measures, such as number of words recalled, were related to age, whereas indirect measures (consistency of order of presentation of words recalled) were not associated with age.
