Statistics is a subject taught in higher education, usually as part of research subject that involves the data analysis routine. One biggest obstacles faced by the students in their research subject is in processing and in interpreting the obtained data. The aim of this study was to apply "lesson study" approach enabling students to collaboratively plan, do, and reflect on their data collection and analysis routines. The study employed qualitatively approach with descriptive method. It is applied to Statistics subject class in four cycle processes consisting of 'Plan, Do, and See'. The participants of the study were the sixth semester students of English Education Study Program. Lesson study was implemented in every cycle as a tool to enhance students' improvement in learning statistics. The exploration of lesson plan was discussed within a team based on the findings in each cycle. As a result, the students were able to process data correctly and meaningfully. They are also able to create informative decision based on the calculated data.
