N2 - In this work we present the process of construction and pilot implementation of an instrument to evaluate the knowledge about stochastic of prospective mathematics teachers, in relation to descriptive statistics content. The tests were carried out in a sample of 126 prospective mathematics teachers, from Spain and Chile. The results are organized starting with some indicators on the psychometric properties of the items analysed and the overall results of the questionnaire. From here, we jointly study the items that conform each category of knowledge of the content in focus, between common or expanded, looking for differences amongst the sample groups. We conclude that the instrument has acceptable characteristics, as well as the items analysed, and its reformed application is projected into the future.
