Data collection used is by collecting student learning style questionnaires then students with visual learning styles are grouped into high, medium, and low groups based on communication skills tests on statistics problems based on written mathematical communication skills. Furthermore, one student from each group category was taken and an interview was conducted related to the achievement of students' oral mathematical communication indicators.
