The role and impact of diversity in higher education has permeated conversations about student access and achievement for many years. Language articulated by various courts suggests that higher education policies should reflect a broad conceptualisation of diversity beyond that of the magnitude and proportion of race and ethnicity, yet…

This dissertation provides a practical approach for measuring operational efficiency and operational effectiveness for IT organizations introducing the ITIL process framework. The intent of the study was to assist Chief Information Officers (CIOs) in explaining the impact of introducing the Information Technology Infrastructure Library (ITIL)…

We propose a new limited-information goodness of fit test statistic C[subscript 2] for ordinal IRT models. The construction of the new statistic lies formally between the M[subscript 2] statistic of Maydeu-Olivares and Joe (2006), which utilizes first and second order marginal probabilities, and the M*[subscript 2] statistic of Cai and Hansen…

The purpose of this study was to use data from the National Longitudinal Transition Study-2 (NLTS2) to (a) conceptually identify and empirically establish student, family, and school constructs; (b) explore the degree to which the constructs can be measured equivalently across disability groups; and (c) examine latent differences (means,…

In the push to bring data to bear on all of the important education issues of the day, one essential fact is often overlooked: Not all indicators are created equal. This book provides a comprehensive approach for understanding how statistical measures of achievement are developed, evaluated, and interpreted. Given the extent to which…

The Census Bureau has historically grouped high school diploma holders along with those who hold "high school equivalent" credentials. Among these is the credential earned through successfully passing the General Education Development (GED) test. Interest in identifying those with GEDs has recently increased, in part from debate within…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

Further explores the difficulties pertaining to limitations in the use and interpretation of the Index of Dissimilarity demonstrates some of the systematic biases resulting from these inadequacies and provides a mathematical refinement which overcomes some of the major problems inherent in the use of this index.

In appraising the Individually Prescribed Instruction system, three sources of information were utilized: a main instrument, the Degree of Implementation Study, and two additional investigations, the Report of Student Progress and the report of the school visitation monitors. To determine the degree of implementation, a sample of the student…

The high cost of providing public services in urban areas of high population density is not always matched by a high capacity to meet that cost. The additional costs that must be borne by taxpayers in urban areas are collectively termed the "municipal overburden." The literature on municipal overburden has failed to recognize that this…

This paper concerns situations in which a p x p covariance matrix is a function of an unknown q x 1 parameter vector y-sub-o. Notation is defined in the second section, and some algebraic results used in subsequent sections are given. Section 3 deals with asymptotic properties of generalized least squares (G.L.S.) estimators of y-sub-o. Section 4…

More attention should focus on sample sizes and the concept of statistical power in research in the field of health, physical education, and recreation. (JD)

Statistical indicators of inequality of educational opportunity developed through this study were applied to 1970 census information concerning school resources and revenues and pupil characteristics to assess the extent of inequality in elementary and secondary schools. Educational equality is defined as the prevailing view that all students…

Demonstrating good reliability for the difference score in measurement, the results of this study indicate that the difference score is often highly reliable when the correlation between true change and true initial status is nonnegative. In general, when individual differences in true change are appreciable, the difference score shows strong…
