Abstrak:
Kemampuan berpikir kritis matematis dan kemampuan komunikasi matematis merupakan kompetensi penting dalam pendidikan matematika abad ke-21, namun sebagian besar siswa masih menunjukkan capaian rendah pada kedua kemampuan tersebut, khususnya dalam pembelajaran statistika. Penelitian ini bertujuan menganalisis kemampuan berpikir kritis matematis dan kemampuan komunikasi matematis siswa dalam menyelesaikan soal statistika dengan mengidentifikasi indikator kemampuan pada setiap tahap pemecahan masalah. Penelitian menggunakan pendekatan kualitatif deskriptif dengan 24 siswa kelas VIII SMP Negeri 15 Kota Cirebon yang dipilih melalui purposive sampling. Data dikumpulkan melalui tes essay dan kemudian dianalisis menggunakan model Saldaña dengan triangulasi teknik. Kemampuan berpikir kritis matematis rata-rata 50,76% berkategori rendah, tertinggi pada analisis masalah (69,79%) dan terendah pada membuat kesimpulan (41,67%). kemampuan komunikasi matematis rata-rata 37,40% berkategori rendah, tertinggi pada penggunaan simbol (80,83%) dan terendah pada penjelasan verbal (63,33%). Diperlukan strategi pembelajaran yang mengintegrasikan aktivitas analitis, argumentatif, dan representatif dalam pembelajaran statistika. Penelitian ini menawarkan analisis terintegrasi kedua kemampuan dalam konteks pemecahan masalah statistika sehingga mengungkap keterkaitannya dalam proses penalaran siswa.
