The data collection technique used essay test related to graphics representation. In addition, an interview was also conducted to confirm students? answer. This research finding shows that statistical reasoning of semester IV students of Mathematics Education whose statistics ability is poor belong to pre-structural level and whose statistics ability is high belong to multi-structural and relational level. The high skilled students could conclude the data with statistical reason even though they used informal terms. Students with multi-structural and relational level regard that variety is a standard showing the numbers of different data among others, not on the different value from the average.

Guru Siswa SDN Panjeng dan MI Muhammadiyah Sidoharjo Pulung belum mampu mengakomodasi kemampuan siswanya dengan lebih. Sementara ini, pendampingan yang dilakukan adalah pendampingan dalam meningkatkan kemampuan pemahaman matematika. Dengan demikian, pihak sekolah membutuhkan pendampingan lebih dari pihak luar agar dapat meningkatkan atau optimalisasi kemampuan siswanya seperti kemampuan problem solving. Kegiatan pengabdian ini dikemas dalam bentuk pendampingan berbasis masyarakat. Peserta pengabdian ini adalah siswa SDN Panjeng dan MI Muhammadiyah Sidoharjo Pulung. Kegiatan pengabdian kepada masyarakat bertujuan untuk mengoptimalisasi dan meningkatkan kemampuan lebih, yaitu kemampuan problem solving pada soal olimpiade matematika dalam bentuk pendampingan yang berbasis masyarakat.
