To determine the effect of format on the communication of information and the range of qualitative reaction, data was presented by bar graphs, data tables and natural language text to 24 staff members of the Southwest Regional Laboratory. No difference in acquisition of information among the staff members was shown. Subjects preferred data tables, and costs and complexities of preparing these tables were found not to be significant in small volume. Procedures of the study are detailed, and attachments provided showing the format used. (SK)
