The relation between average deviation, as determined using the Illinois Test of Psycholinguistic Abilities, and Stanford-Binet intelligence scores was examined using a preschool sample. Results revealed a curvilinear relation between total average deviation and Stanford-Binet intelligence scores. Use of average deviation as an index of…

This document contains statistical demographic information describing the gender, age, and ethnicity of the 57,772 students enrolled at City College of San Francisco (CCSF) during the fall 1997 semester, as well as the ethnicity of the faculty, classified staff and administrators working at CCSF at that time. The report includes 1996 figures for…

The mini-computer is found to be a viable alternative to large computer bio-medical information processing. (Author/RS)

Reviews the Sixth Berkeley Symposium on Mathematical Statistics and Probability, in which participants sought to establish a realistic cross-section of contemporary statistical thinking about the effects of pollution on health. Present information of health effects of pollutants is fragmental, and further studies are urgently required for…

Rebuttal to Gage's view that the elimination of racial differences depends on education, not on eugenics. (MF)

Discusses the heritability of intelligence. (MF)

Describes the problems, procedures, findings, and implications for education of a study designed to identify the ideal teacher as related to classroom behavior traits. (GR)

The reliability of simple difference scores is greater than, less than, or equal to that of residualized difference scores, depending on whether the correlation between pretest and posttest scores is greater than, less than, or equal to the ratio of the standard deviations of pretest and posttest scores. (Author)

Calls attention to limitations and dangers in routine application of multivariate analysis of variance (MANOVA), describes some alternative procedures, and laments the necessarily pervasive character of the statistical problem. (Author)

Data for four-, five-, and seven-position Likert formats from 292 undergraduates showed systematic error varied among formats, i.e., central tendency errors tended to increase with increasing number of categories and to reduce variances expected. (Author)

Basic rules are suggested to replace the signed coefficient rule to infer the form of moderator effects in terms of slopes of regression lines. Steps are provided to interpret the form of moderator effects that can be achieved using only the regression coefficients of the predictor variable and interaction term. (SLD)

Effects of different weighting schemes on selecting the optimal number of observations in multivariate-multifacet generalizability designs are studied when cost constraints are imposed. Comparison of four schemes through simulation indicates that all four produce similar optimal values and that reliability should be similar. (SLD)

Rasch model total-fit statistics and between-item fit statistics were compared for their ability to detect measurement disturbances through the use of simulated data. Results indicate that the between-fit statistic appears more sensitive to systematic measurement disturbances and the total-fit statistic is more sensitive to random measurement…
