Abstract : The purpose of this study is to define the most effective data presentation style for a given type of task. Three display modes are proposed in this study: Color, 3-Dimensional bars and lines or 2-Dimensional. However, only the color condition has been tested. The study requires subjects to answer questions concerning the relative levels of each graphic dimension. However, one type of question requires integrative thinking (trend analysis) and the other requires focused thinking (point reading). Selection of the different display modes are based on the principle of proximity compatibility or providing an integrated format for integration based questions. The results support our hypotheses about the effectiveness of graphic displays. We constructed our own fictional database of information regarding cadet physical performance and designed balanced questions to test two types of information processing.
