Statistical literacy provides the capacity of abstraction to be able to perform an exploratory analysis of data. For this reason, statistics is necessary in the education of citizens, since it allows them to understand and analyze their environment. This is how we see it present in all curricula from elementary school to university. For this reason, a study of statistical literacy and its components in future mathematics teachers is presented. This work was developed as a quantitative research. The results obtained show that future mathematics teachers have not mastered the basic concepts of statistics. They do not have the instrumental knowledge of statistics necessary for its application in practice, reflected in the conceptual errors identified: incorrect application of properties, they do not appreciate the effect of an outlier in the calculation of the mean, they are not able to discern when a value is outlier for a given context, there is no mastery in the interpretation of a graph and its association with the concept of arithmetic mean. Despite this, they have a positive attitude towards statistics.
