ABSTRACT
All this time, there is not much information about the level of student statistical thinking and the increase in student learning achievement in class. Therefore, a study was conducted with the aim of explaining students’ statistical thinking skills at each level of statistical thinking, and the achievement of the improvement during one semester of learning. The results will be used to develop lesson plans for teaching needs. In addition, there is an urgency to reform conventional learning into online classes that teach introductory statistics, how students learn statistics, and how to assess learning outcomes.
