Educational research on the factors of student achievement has been limited by its failure to consider the multilevel or hierarchical nature of most data. This study used a nonexperimental regression-based procedure, hierarchical linear modeling (HLM), to empirically develop a predictive model of fifth-grade achievement in reading and mathematics…

Some issues in defining dropouts and reporting information about them are explored, with reference to the Common Core of Data (CCD) survey of the National Center for Education Statistics. There has not been any uniform national count of how many students leave school, and no commonly accepted definition has been developed that allows a number to…

This guidebook is designed for data analysts who are working with computer data files that contain records with incomplete data. It indicates choices the analyst must make and the criteria for making those choices in regard to the following questions: (1) What resources are available for performing the imputation? (2) How big is the data file? (3)…

Problems involved in providing practical research experience in research methods courses are discussed. The two points in the research process where time is most critical are selecting measures and data collection. This paper suggests using a data base from previous research and having students conduct simulated studies based on randomly selected…

Technological advances in microcomputer hardware and software, including size of memory and increasingly more sophisticated statistical application packages, create a new era in educational research. The alternative to costly main-frame computer data processing and statistical analysis is explored in this paper. In the first section, typical…

All secondary school assistant principals in Massachusetts were surveyed to assess the relationships between their backgrounds, training, and values and their concepts of, preparedness for, and processes for dealing with conflict situations. Data were collected through questionnaires and through the completion by the 122 survey respondents of the…

In order to assess the methodological merit of the published research in educational administration based on surveys, the authors analyzed data from a random sample of 24 survey studies published in the "Education Administration Quarterly" and the "Journal of Educational Administration." Each article was evaluated according to…

This manual is intended to improve both the design of longitudinal studies and analysis of the resulting data. Issues related to educational and developmental research have been emphasized in these eight chapters. Topics of particular interest to longitudinal researchers include stochastic models of developmental change, mathematical…

This document is part of a series of chapters described in SO 011 759. The chapter examines the merits of four estimators in the causal analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable). The four procedures are ordinary least squares, Kaplan-Meier least squares, maximum…

The degree to which the chosen units of analysis are likely to produce spurious findings in staged combinations of multiple linear regression procedures are examined. The effects of grouping variables (e.g., classroom, school, and school district) on Procedures such as Coleman's semipartial regression and Mayeske's commonalities, in light of…

Problems encountered in large-scale educational evaluations are discussed using the evaluation of the Emergency School Aid Act as an example. This extensive article focuses primarily on methodological issues. (JKS)

Within-class regression is a method, developed in this paper, of comparing a large number of nonequivalent groups. This study indicated that within-class regression was a less biased method of data analysis and will yield more accurate estimates of treatment effects than analysis of covariance. (PN)

Examines data analysis at three levels: analysis of data; secondary analysis is the re-analysis of data for the purpose of answering the original research question with better statistical techniques, or answering new questions with old data; and, meta-analysis refers to the statistical analysis of many analysis results from individual studies for…

Criticized in this response is research published previously in "The Journal of Environmental Education." Considered are the limitations of the project, experimental design, control of variables, and the use of the case study approach. Includes 35 references. (CW)

Illustrates how the combined use of qualitative and quantitative methods were necessary in obtaining a clearer understanding of the process of incest in American society. Argues that the exclusive use of one methodology would have obscured important information. (FMW)
