Mathematics is a subject that inspires vision and sets a standard for scientists, particularly in the realm of logical intelligence. Mathematics research is increasingly focused on global challenges. for students are constructing breakthroughs in critical thinking and problem-solving.This research aims to describe the types of errors students make while solving Higher Order Thinking Skills (HOTS).Type statistics math problems and identify factors causing errors in solving HOTS.The research method uses both experimental and qualitative methods, including case studies. Nineteen students from class VIII-A were involved in using test, interview, and documentation methods for data collection. The techniques employed in analyzing data include data reduction, presentation, and conclusion. To ensure data accuracy, triangulation techniques are employed, precisely source triangulation. The results indicated that students made various errors in question 1, including reading, comprehension, transformation, skill, and final answer writing errors. Question number 2: errors can occur in reading, understanding, transforming, skill application, or last answer writing.3) Question number 3 includes reading, transformation, and process skills errors. The errors are caused by students needing to read statements and questions carefully. The crucial factor for students to solve problems is retrieving data from the details of the questions for error analysis, Newman, HOTS, and statistics.
