Abstract
Visual displays are often used to facilitate communication of important medical information to patients. However, even the simplest graphs are not understood by everyone. In this chapter, we develop and test a scale to measure health-related graph literacy and investigate the level of graph literacy in the USA and Germany. The scale was developed in the laboratory and tested on national samples in the two countries. The graph literacy scale predicted which patients can benefit from visual aids and had promising measurement properties. Results showed that approximately one-third of the population in the USA and Germany had both low-graph literacy and low-numeracy skills.
In this chapter, we partially reproduced the article Galesic, M., & Garcia-Retamero, R. (2011). Graph literacy: A cross-cultural comparison. Medical Decision Making, 31, 444−457.
