Recent research findings concerning analysis of covariance (ANCOVA) are reviewed, its use is illustrated, and a method for performing it using the Statistical Package for the Social Sciences is presented. In addition, methods for examining Elashoff's seven assumptions as a prerequisite to the correct application of ANCOVA are discussed.…

A research project developed a computer program for analyzing time series quasi-experimental data. The program generates a nonstationary, integrated moving average time series model; it is used to estimate a parameter which indexes the instantaneous change in level of the time series due to a predesignated treatment. The entire method is based on…

Scott's coefficient is an improved method for estimating observer reliability using any system which assigns events to mutually exclusive categories. The formula is the ratio of the actual difference between obtained and chance agreement to the maximum difference between obtained and chance agreement. A FORTRAN program for calculating this…

The purpose of this discussion is both to demonstrate that the trend in educational research is definitely moving towards a quantitative-empirical dominance and to show that quantitative analysis and computer methods are independent of subject matter emphasis while providing insights into extremely important policy issues in education.

The Mann-Whitney U Test provides an alternative to the parametric test when applied to the kinds of ordinal data typically generated by semantic differential and Likert-type scales. The application of this test to survey research problems in business education is discussed, and a computer program is given for the use by the business education…

Description of Sociology Library (SOLIB), presented as a package of computer programs designed for smaller computers used in research methods courses and by students performing independent research. (Author/ND)

Student data banks for ongoing research and evaluation have been implemented by a number of professional schools. Institutions selecting software designs for the establishment of such systems are often faced with making their choice before all the possible uses of the system are determined. Making software design decisions involves "rational"…

The objective of this project was to investigate the adequacy of statistical models developed by G. E. P. Box and G. C. Tiao for the analysis of time-series quasi-experiments: (1) The basic model developed by Box and Tiao is applied to actual time-series experiment data from two separate experiments, one in psychology and one in educational…

Discusses the application of the Kolmogorov-Smirnov two-sample tests, as an alternative to the Chi-square test, for survey research problems in business education and includes a computer program written for the convenience of researchers. The two-sample test is recommended for differentiating independent distributions. (MF)

Reported is a method for the analysis of qualitative data, based on the linguistic device of systemic networks used to represent a structure of possibilities. Some initial applications are described, and work in progress, including a computing system, is outlined. (Author/HM)

This document contains summaries of six courses presented at the Second Annual Presessions of the American Educational Research Association: (1) Bayesian statistical analysis, (2) curriculum research and evaluation, (3) design and analysis of comparative experiments in education, (4) educational research management procedures, (5) multivariate…

The main purpose in developing the "package" of computer programs described in this guide is to use the automated capability of computers in the enormous job of handling anthropological field data. It is held that ethnography may be threatened with absolescence simply becasue so many man hours are involved in filing and sorting these…

The primary purpose of this volume is to serve as a "how to" manual for individuals interested in replicating or expanding the data collected by the Studies. Two introductory sections discuss the development of the methodology and the organization of the methodology description. The three subsequent chapters, which constitute the body of…

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…

Recent research results strongly suggest that the theoretical problems of change measures have limited practical significance for measuring individual growth, and it is important to determine whether this is also the case for measuring school impact. Accordingly, in this study artifical data were used to assess the correlation between several…
