This study was designed to investigate the impact that collective negotiations have had on teachers' salaries in Ohio; and the relationships between the incidence of work stoppages and the characteristics of Ohio school districts. Since the focus of this was twofold, it was found necessary to employ several statistical techniques to accomplish the objectives of the study. The first part of this report deals with the model and data base used to explain the variance of average salaries for public school teachers in Ohio. Another section sets forth the research design used in ascertaining the characteristics of school districts that had strikes. Empirical data presented in the report show the results of the factor and discriminant analysis. Conclusions and recommendations are also presented. (Author/JF)
