Abstract

The ability to represent mathematical concepts is one of the crucial skills. However, this skill has not developed well. This study aims to explain how ninth-grade junior high school students can demonstrate mathematical representation related to verbal, pictorial, and symbolic elements. The descriptive quantitative method is used in this study, which involves the analysis of descriptive statistical data. There are 33 junior high school students in Karawang Regency who are the subjects of the study. This study uses a series of tests consisting of six questions based on the metrics of mathematical representation ability. The collection of student ability categories, average, and standard deviation were calculated for data analysis. As shown by the research results, students do not have ideal mathematical representation skills. While most students have moderate scores, their average is still below standard. Image representation reached the highest level, while verbal representation reached the lowest level. These findings show that students struggle to convey mathematical concepts and relate various representations when solving statistical problems. Therefore, a more structured learning method is needed to strengthen students' abilities in mathematical representation.
