This article discusses teachers’ images on statistics and its teaching. It began with their trajectories to explain the formation of images on statistics and how through participation in a professional development program these images were transformed. The participants of this research were 10 in-service teachers who were responsible for teaching statistics either in elementary (6-11 years), middle (11-15 years) or high school (15-17 years) in public schools in Medellin, Colombia. The teachers participated in a professional development program inspired by the social learning theory in which they designed statistical lessons, put them into practice and reflected on the implementation. The sources of information were their discourses in the program, autobiographical writings, reflective writings and semi-structured interviews. The results revealed that teachers began with static, technical, and un-transformable images of statistics and they started to construct images of statistics as a tool for empirical inquiry.
