Abstract	Tested the effects of visualizing statistical information. In their research articles, scholars often use 2 x 2 tables or tree diagrams including natural frequencies in order to illustrate Bayesian reasoning situations to their peers. The present article reports on an empirical study (3 x 2 x 2 design) which systematically varied visualization (no visualization vs. 2 x 2 table vs tree diagram) and information format (probabilities vs natural frequencies) for two contexts (medical vs economical context; not a factor of interest). Each of 259 high school students (age 16-18 years) had to solve two typical Bayesian reasoning tasks (mammography and economics problems). Results indicate that 2 x 2 tables and tree diagrams, particularly when natural frequencies are included, can foster insight into the notoriously difficult structure of Bayesian reasoning situations. In contrast to many other visualizations (e.g., icon arrays, Euler diagrams), 2 x 2 tables and tree diagrams have the advantage that they can be constructed easily. The implications for teaching Bayesian reasoning are discussed. (ZPID).
