These symposium papers discuss the instructional use of computers in psychology, with emphasis on computer-produced simulations. The first, by Rich Edwards, briefly outlines LABSIM, a general purpose system of FORTRAN programs which simulate data collection in more than a dozen experimental models in psychology and are designed to train students…

This is the second of two supplements to a manual on the self-evaluation of drug abuse treatment programs. Data based on treatment outcome information that agencies and clinics routinely collect or have available in the files of individual clients are presented. While it is possible to use this volume without referring to the discussion of…

A DESCRIPTION IS GIVEN OF ITEM SAMPLING, OR "PSYCHOMETRIC-STATISTICAL INFERENCE," AN APPROACH TO GATHERING AND USING EDUCATIONAL DATA THAT ALLOWS STATISTICAL INFERENCES TO BE MADE SIMULTANEOUSLY WITH PSYCHOMETRIC INFERENCES. THIS IS A PROCEDURE IN WHICH BOTH PEOPLE AND ITEMS ARE SAMPLED AND THE DATA FROM A SAMPLE OF PEOPLE TAKING A SAMPLE OF ITEMS…

Five papers published in a special edition of Human Factors, August 1973 are examined in an attempt to explain and illustrate the characteristics and applications of central-composite designs in the context of response-surface methodology (RSM). A detailed analysis is provided to show that the experimental papers (1) fail to illustrate the most…

In the controversy regarding the relationship of the cost per student to the size of the school, some argue that economics of scale exist while others insist that they do not. The purpose of this study was to estimate the net relationship between the enrollment size of an area vocational technical school and the expenditures per student. The…

This eight city pilot survey tested the feasibility of conducting a nationwide mail survey of training in business and industry, including feasibility of the project for specific industry groups. Other objectives were to specify subject areas on which data might or might not be available; suggest a single questionnaire or series of questionnaires;…

Teachers and assistant teachers (N = 32) from two rural counties in North Carolina rated five pre-school educational settings and one hypothesized ideal setting using a semantic differential in order to determine if the semantic differential could be used to reliably differentiate between pre-school educational environments. Five discrepancy…

THIS INVESTIGATION WAS DESIGNED TO PROVIDE DATA ABOUT THE CHARACTERISTICS OF SOCIAL-POLITICAL ACTION LEADERS AT ONE UNIVERSITY AND TO COMPARE THOSE CHARACTERISTICS WITH OTHER TYPES OR CATEGORIES OF STUDENT LEADERS. NINE RESEARCH HYPOTHESES IN NULL FORM WERE FORMULATED TO FACILITATE STATISTICAL TREATMENT OF THE DATA. FROM A TOTAL OF 559 ELECTED…

The National Food and Agriculture Council of the Philippines regularly requires rapid feedback data for analysis, which will assist in monitoring programs to improve and increase the production of selected crops by small scale farmers. Since many other development programs in various subject matter areas also require similar statistical…

Examines some questions arising in connection with the application and usefulness of Bradford's Law, which describes the dispersion of articles on a particular subject among journal titles. (Author)

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)

Several statistical rational and empirical procedures are presented for dealing with the problems of non-response or low return rates in surveys, namely mail surveys. Advantages and shortcomings of these procedures in educational research are discussed. (SLD)

To establish a sophisticated planning mechanism that will translate readily to affordable tactical steps, university planners must have a good understanding of the cost structure of individual academic and administrative departments and of the efficiency and effectiveness of the staffs of those departments. (MLW)

Microcomputer uses by social researchers include writing programs, standard spreadsheets and data base management. In addition, microcomputers can increase the effectiveness and efficiency of information gathering by improving notetaking and organizing. Software developments will help make microcomputer data base management tools, now not…

Enrollment data for 1977-1982 are used to produce an innovative map of top 42 elective courses in Drexel University's School of Library and Information Science. Data gathering and computing procedures are given in sufficient detail for replication and evidence is relevant to accreditation standards of American Library Association. (Sixteen…
