Statistical literacy is the ability of understanding, interpreting, and evaluating information critically. The ability of statistical literacy is a benchmark in order to know students’ awareness about information. Therefore, it is important to identify students' statistical literacy abilities and how far students are able to use the information in a better way. The aim of this study is to reveal the students’ statistical literacy ability of junior high school students in mathematics class, based on four indicators, (1) understanding the basic terminology of statistics and the opportunity to understand information; (2) interpreting statistical messages; (3) making conclusion and a decision; (4) evaluating information critically. The research method is descriptive. The subjects of this research are 7th grade students of  SMPN 2 Bangkalan. The results show that, students have good understanding of statistics and probability terminology, students were able to interpret statistical messages in graphical form, but most of the students are weak to interpret data that is presented in the form of pie charts. The ability to evaluate and make a conclusion that is made by most students is not based on mathematical calculations, so that the effect in making decisions is not efficient. The conclusion is the subjects have statistical literacy ability in understanding, interpreting, and making conclusions, but have not reached the stage of evaluating information critically.
