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.…

The attached materials have been developed for use on the CSU CYBER Computer's Statistical Package for the Social Sciences (SPSSONL). The assignments are graded in difficulty and gradually introduce new commands and require the practice of previously learned commands. The handouts begin with basic instructions for logging on; then XEDIT is taught…

This document discusses the creation of a new formal language for the field of counseling psychology. Constructs for such a language are applied specifically to the communication of research information (especially research concerned with the effects of counselor action on clients) for experimental replication. Grammatical concepts of a formal…

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"…

This study was conducted to determine the effects of using various levels of tutorial statistical software for the tentative identification of nonseasonal ARIMA models, a statistical technique proposed by Box and Jenkins for the interpretation of time-series data. The Box-Jenkins approach is an iterative process encompassing several stages of…

Traditional measures of proximity all share three common weaknesses: (1) they are based on ratio-level measurement of physical distance that may not correspond to "psychological distance;" (2) they measure distance as a fixed rather than variable quantity; and (3) they measure distance between pairs of individuals rather than larger groups of…

This document presents a modified cohort survival model which can be of use in making enrollment projections. The model begins by analytically profiling an area's residents. Each person's demographic characteristics--sex, age, place of residence--are recorded in the computer memory. Four major input variables are then incorporated into the model:…

EXPER SIM has been translated into two basic software systems: the Michigan Experimental Simulation Supervisor (MESS) and Louisville Experiment Simulation Supervisor (LESS). MESS and LESS have been programed to facilitate student interaction with the computer for research purposes. The programs contain models for several statistical analyses, and…

An interactive, computerized model developed for Old Dominion University utilizes university historical data, demographic characteristics, projected selected economic variables and population figures by various age groups and planning districts to forecast enrollment, financial projections, and future fiscal conditions of the institution. The…

A method for modeling the structure of large social systems has been developed which is based on the interpersonal communication networks present in the functioning system. Recent developments in techniques and computer software have made possible the analysis of networks of several thousand persons. The new technique provides a method for…

This report treats some of the technical difficulties encountered in lexicological studies that were undertaken in order to establish a basic vocabulary. Its purpose is to show that the computer can overcome some of these difficulties, and specifically that computer programming can serve to establish a vocabulary common to scientific and technical…
