The representation of statistical information in the form of natural frequencies is one of the main factors that support Bayesian reasoning. However, materials for professionals in the fields of medicine or law usually present information in the form of probabilities. Therefore, one aim of our research is to develop a training for professionals in those fields. In this paper, we present a short intervention that uses unit squares as visualization of statistical information. We report on a pilot study where students at university were trained how translate the usual probability format to a frequency format and how to visualize the statistical information. The results encourage the approach to use unit squares as visualizations of statistical information for training Bayesian reasoning.
