The Cost and Funding Studies project of the proposed Western Interstate Bibliographic Network began activities in July 1975. The goals of the project were to: (1) determine representative costs of present library services in the West, (2) estimate future costs of library services in the West with proposed network support, (3) evaluate and compare…

The unbiased estimate of a "treatment effect" reached by analysis of covariance in a nonrandomized experiment would often require that a different covariate be used in each treatment. A sufficient but unlikely condition for an unbiased estimate is that the covariate for each treatment is (1) the complete covariate that predicts the outcome as…

The optimum weighting of variables to predict a dependent-criterion variable is an important problem in nearly all of the social and natural sciences. Although the predominant method, multiple regression analysis (MR), yields optimum weights for the sample at hand, these weights are not generally optimum in the population from which the sample was…

This study investigated the effect of a program designed to prepare teachers for integration of handicapped students into the regular class. (Editor)

Research design sampling models regarding educational research of within-grade influences on overall educational experiences are discussed and limitations of each model noted. (DEP)

This article reviewed literature relating to growth stages in children and how these growth stages influence what is drawn. Additionally, a review of research was presented using the human-figure drawing in measurement of intelligence, personality assessment and prediction of learning performance. (Author/RK)

The DELPHI procedure requires respondents to reply to several questionnaire iterations with subsequent rounds containing previous round feedback. This study investigated the methodology (response rates, effects of feedback) and offered evidence that large-scale DELPHI surveys are not as advantageous as has previously been indicated. Suggestions…

A debate concerning specific issues and the general usefulness of the Rasch latent trait test model is continued. Methods of estimation, necessary sample size, and the applicability of the model are discussed. (JKS)

A national sample of pupils in multiracial schools answered questions about their actual and desired friendship choices. The sample comprised 1288 pupils in the second and fourth years of junior schools and 3012 pupils in the second and fourth years of secondary schools. (Author)

Describes how a computer program which simulates four techniques of town sampling can be used to teach survey sampling in a college level social research methods course. (Author/DB)

Linear conversions were developed relating scores on recent forms of the Graduate Record Examinations. Conversions based on specially selected subpopulations were compared with total-group conversions and evaluated. Conclusions indicated that the data clearly support the assumption of population independence for homogenoeous tests, but not quite…

Khuri's and Satterthwaite's methods of obtaining confidence intervals of variance components are compared. The article discusses that Khuri's method may be applied to obtain confidence intervals for the variance components and other linear functions of the expected mean squares used in generalizability theory. (Author/JAZ)

This "Technical Guide" describes the methodology and concepts used to measure and grade the performance of the 50 states in the higher education arena. Part I presents the methodology for grading states and provides information on data collection and reporting. Part II explains the indicators that comprise each of the graded categories.…

This study addressed statistical techniques that might ameliorate some of the sampling problems currently facing states with small populations participating in State National Assessment of Educational Progress (NAEP) assessments. The study explored how the application of finite population correction factors to the between-school component of…

This report is the last in a three-part series examining the relationship between school resources and student achievement in California. The central focus in all three reports has been the standards-based reform of California public schools. Between 1995 and 1998, California introduced academic content standards specifying what students should…
