This paper reviewed two different approaches to statistical literacy. The first approach is made by Gal. While the second approach is done by Watson. Gal describes the statistical literacy in a statistical model containing two elements, the knowledge element and the disposition element. The knowledge element of the Gal’s model consists of five skills, that is literacy skills, statistical knowledge, mathematical knowledge, context knowledge and critical questions. While the element of disposition consists of critical stance and beliefs and attitude. Unlike Gal, Watson describes the statistical literacy in a hierarchical way. In the Watson’s model, the statistical literacy is consist of six levels. This paper begins by explaining the importance of statistical literacy for individual daily life and the importance of teaching statistical literacy since school age. Then the authors examine the relevance of both models, from equations and differences. In this paper also examines how the implications of these two statistical literacy approaches to school instruction.
