Some empirical issues in research on academic departments: Homogeneity,aggregation, and level of analysis

This study investigated the appropriateness of the academic departmental level of analysis. Homogeneity of faculty members' responses to measures of organizational structure, environmental uncertainty, and task routineness was examined to determine the legitimacy of aggregating those responses to create departmental level variables. Analysis of variance suggested that the structure and environmental uncertainty subscales were measuring departmental level phenomena, but that the task routineness scales were not. Results demonstrate the importance of empirically testing, rather than assuming, levels of analysis in studies of academic departments.
