This study presents a novel method for the collection and graphical representation of group evaluation data that enables the simultaneous display of outcomes across units of analysis. This method affords the researcher/practitioner improved options for simultaneously evaluating and comparing individual and group change over time. Data for this study are drawn from 10 experiential, group psychotherapy training groups that met on a weekly basis. A total of 185, second-year graduate social work students evaluated their satisfaction with their personal and group experience across eight dimensions. A multiple page Excel spreadsheet was developed for the collection, computation, and visual representation of scores from the evaluation instrument. Three-dimensional surface plots are used here to simultaneously represent individual and group outcomes. Surface plots provide a visual display of the topography of group and individual change over time. This data visualization method utilizes readily available technology to display group outcomes at multiple levels of analysis.
