Abstract
Lack of mathematical problem-solving ability causes students to have difficulty solving problem-solving problems. This study aims to determine the mathematical problem-solving ability of students in solving statistical problems. The research method is qualitative with a descriptive type. The research subjects consisted of 4 students of class IX in one of the SMP Negeri Pakenjeng. Data collection techniques used test questions, interviews, and research notes, then analyzed using data reduction, data presentation, and concluding/verification. The results showed that the achievement for indicators identified data adequacy as much as 19%, for indicators making mathematical models of situations or everyday problems as much as 56.25%, for indicators applying strategies to solve math problems or outside mathematics as much as 62.50%, and for indicators explain or interpret the results according to the original problem and check the correctness of the results as much as 62.50%. Overall, students' mathematical problem-solving abilities in statistics material are of low qualification so they need to be improved.
