This paper considers the model of school effectiveness (SE) currently dominant in research, policy and practice in England (although the concerns it raises are international). It shows, principally through consideration of initial and propagated error, that SE results cannot be relied upon. By considering the residual difference between the…

This document reviews "The Collected Works of George E. P. Box," edited by G. C. Tiao. The two-volume collection is divided into five parts. Each part is prefaced with an introduction by a statistical researcher giving his view of the motivation and highlights of the papers presented. The 16 papers in Part 1 on statistical inference,…

Approximations to the distribution of a common form of effect size are presented. Single sample tests, confidence interval formulation, tests of homogeneity, and pooling procedures are based on these approximations. Caveats are presented concerning statistical procedures as applied to sample effect sizes commonly used in meta-analysis. (Author)

Methods for selecting relevant and appropriate quasi-experimental studies for inclusion in research synthesis using the threats-to-validity approach are presented. Effects of including and excluding studies are evaluated. (BS)

This study examines the relationship between high-stakes school accountability and its effects upon student test scores and school policies. The authors seek to understand the extent to which accountability sanctions and incentives for the poorest-performing schools in Florida explain subsequent changes in school practices and policies as well as…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

This study presents a scheme for yearly, comparative, computation of state and local government tax capacity and effort. Figures for all states for fiscal year 1975 are presented in extensive tables. The system used is a simplified version of the Representative Tax System, which identifies tax bases, determines national average tax rates for those…

This paper examines interaction in a school class through the factor-analytical P-technique, considers the behavior of the factor scores in combination with certain other variables included in the interaction matrix, explores the formation of homogeneous groups of lessons in a grouping analysis based on the factor scores, and compares this latter…

Extending the classical twin method, Arthur R. Jensen claims to find unique estimates of the variance and covariance of the genetic and environmental components of IQ. The analyses presented in this paper show that a wide variety of parameter estimates are compatible with his model and data. But the extent of indeterminancy is deemed to be even…

This study bears on Arthur R. Jensen's latest statement on the heritability of intelligence. Allowing for gene-environment correlation, Jensen (1975) reports that under a wide range of assumptions, the twin data show that one-half to three-fourths of IQ variance is accounted for by genetic factors. This conclusion falls when an arbitrary…

Examines the importance of defining terms in the process of gathering statistical data. Cites the example of the debate over the number of children abducted by strangers. Concludes that statistics are part of the persuasive rhetoric of social problem promotion and have social consequences. (FMW)

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

In part stimulated by the information needed by the Private Industry Councils (PICs) under the Comprehensive Employment and Training Amendments (1978), a growing number of groups and agencies have conducted surveys of local employers to gather various types of occupational data. Such activities may be useful and productive, if the data collection…

Understanding that the behavior of people takes place within a context, over the past 20 years research in education and the sport sciences has witnessed an increasing development of multilevel frameworks that are both conceptually and methodologically sound. Despite these advances, the use of multilevel models and research designs in education…

COMPUTER PROGRAMS AND OPERATING INSTRUCTIONS WERE REPORTED FOR USE IN PROCESSING DATA ON TEACHER ROLES. INCLUDED IN THE OVERALL DATA-PROCESSING METHOD WERE--(1) A PROGRAM FOR TABULATING CONTINGENCY TABLES FROM DATA ON PUNCHED CARDS, (2) A PROGRAM FOR SELECTING AND COMBINING ROWS AND CALCULATING MANN-WHITNEY MEASURES OF SIGNIFICANT DIFFERENCES…
