Materi statistika merupakan salah satu materi yang dianggap sulit yang menyebabkan siswa belum memenuhi Kriteria Ketuntasan Minimal (KKM) dan berakibat hasil belajar pada materi statistika masih tergolong rendah. Salah satu faktor penyebabnya yaitu model pembelajaran yang diterapkan oleh guru masih belum sesuai. Model pembelajaran Problem Based Learning (PBL) merupakan salah satu model pembelajaran yang dapat diterapkan untuk mengefektifkan pembelajaran pada materi statistika. Penelitian ini bertujuan untuk mengetahui efektivitas penerapan model pembelajaran Problem Based Learning (PBL) efektif pada materi statistika kelas VIII di SMP Negeri 3 Banda Aceh. Penelitian ini merupakan penelitian kuantitatif secara deskriptif, dengan menerapkan pre-experimental design dan bentuk penelitian yaitu one-shot case study. Sampel pada penelitian ini adalah kelas VIII-4 SMP Negeri 3 Banda Aceh dengan jumlah 29 siswa, yang diambil secara acak. Hasil analisis data menyatakan bahwa penerapan model pembelajaran Problem Based Learning efektif pada materi statistika kelas VIII SMP Negeri 3 Banda Aceh.Berdasarkan hasil penelitian dan pembahasan yang telah dikemukakan maka dapat
disimpulkan bahwa penerapan model pembelajaran Problem Based Learning (PBL) efektif pada materi statistika kelas VIII di SMP Negeri 3 Banda Aceh. Hal ini diperoleh dari (1) kemampuan guru mengelola pembelajaran termasuk dalam kategori sangat terlaksana dengan nilai rata-rata 3,82; (2) aktivitas siswa setelah pembelajaran mencapai 90,84% dalam kategori sangat aktif; (3) ketuntasan belajar klasikal
mencapai persentase sebesar 93,10%; dan (4) angket respon siswa mencapai persentase 89,25% dalam kategori baik.

Statistics material is one of the materials that is considered difficult which causes students not to meet the Minimum Completeness Criteria (KKM) and results in learning outcomes in statistics material are still relatively low. One of the factors causing this is that the learning model applied by the teacher is still not appropriate. The Problem-Based Learning (PBL) learning model is one of the learning models that can be applied to streamline learning in statistics material. This study aims to determine the effectiveness of the application of the effective Problem-Based Learning (PBL) learning model in statistics material class VIII at SMP Negeri 3 Banda Aceh. This research is descriptive quantitative research, by applying pre-experimental design and the form of research is a one-shot case study. The sample in this study was class VIII-4 SMP Negeri 3 Banda Aceh with a total of 29 students, who were taken randomly. The results of the data analysis state that the application of the Problem-Based Learning learning model is effective in statistics material in class VIII SMP Negeri 3 Banda Aceh. Based on the results of the research and discussion that has been stated, it can be concluded that the application of the Problem-Based Learning (PBL) learning model is effective in class VIII statistics material at SMP Negeri 3 Banda Aceh. This is obtained from (1) the teacher's ability to manage learning is included in the category of highly implemented with an average score of 3.82; (2) student activity after learning reached 90.84% in the very active category; (3) classical learning completeness reached a percentage of 93.10%; and (4) student response questionnaire reached a percentage of 89.25% in the good category.
