Abstract
Word problems in mathematics has always been a challenge for students and teachers. This study aims to investigate students^ errors in solving statistical word problems using case study methodology. 88 Grade 9 students were given a test consist of four word-problems. The problems used were integrating statistical elements such as tables and diagrams. Students work were analyzed to find the conceptual, procedural, and technical errors. Eight students were selected and interviewed to gather information about their thinking and strategies in solving the problems. This information provides complimentary data on their errors. The results show that the conceptual errors include using incorrect formulas, and misunderstanding the statistical concepts. The procedural errors made by the students include incomplete steps in solving problems for example missing the conclusion. Students made technical errors when calculation decimal numbers.
