<![CDATA[Low levels of statistical literacy, as indicated by an average statistical literacy score of 40.6% among prospective teachers, are caused by a lack of connection between the theory taught in class and its application in real life. The integration of Case-Based Learning (CBL) with hypermedia can create an interactive and contextual learning environment, thereby enabling the development of statistical literacy. The objectives of this study include describing the development process, assessing the feasibility, and evaluating the effectiveness of hypermedia-assisted CBL e-modules in supporting statistical literacy. This study uses the Research and Development (R&D) method with reference to the Lee and Owens model. The research subjects consisted of three subject matter experts, three media experts, and 30 students from the Chemistry Education Study Program at a state university in Banten Province. Data were collected through interviews, questionnaires, and statistical literacy tests. Data analysis was performed using descriptive and inferential statistics. The development process went through the stages of needs analysis, design, development, implementation, and evaluation. The results showed that the hypermedia-assisted CBL-based e-module was feasible, practical, and effective in improving students' statistical literacy. This is evidenced by expert validation results showing a feasible category (78.5%), positive student responses (79%), and a significant increase in statistical literacy scores after using the e-module. These findings imply that the integration of CBL and hypermedia can be used as an alternative learning strategy that is more interactive and contextual to strengthen statistical literacy. This model is recommended for adoption in the development of digital learning media in statistics courses and similar fields that require data analysis skills. Abstrak Rendahnya tingkat literasi statistika ditandai dengan rata-rata skor literasi statistik sebesar 40,6% pada calon guru disebabkan oleh kurangnya keterhubungan antara teori yang diajarkan di kelas dengan penerapannya dalam kehidupan nyata. Integrasi Case-Based Learning (CBL) dengan hypermedia dapat menciptakan lingkungan pembelajaran yang interaktif dan kontekstual, sehingga memungkinkan berkembangnya literasi statistika. Tujuan penelitian ini meliputi mendeskripsikan proses pengembangan, menilai kelayakan, dan mengevaluasi efektivitas e-modul CBL berbantuan hypermedia dalam mendukung literasi statistika. Penelitian ini menggunakan metode Research and Development (R&D) dengan mengacu pada model Lee dan Owens. Subjek penelitian terdiri atas 3 ahli materi, dan 3 ahli media, serta 30 mahasiswa Program Studi Pendidikan Kimia di salah satu Perguruan Tinggi Negeri di Provinsi Banten. Data dikumpulkan melalui wawancara, angket, dan tes literasi statistika. Analisis data dilakukan menggunakan statistik deskriptif dan inferensial. Proses pengembangan melalui tahapan analisis kebutuhan, perancangan, pengembangan, implementasi, dan evaluasi. Hasil penelitian menunjukkan bahwa e-modul berbasis CBL berbantuan hypermedia layak, praktis, dan efektif dalam meningkatkan literasi statistika mahasiswa. Hal ini dibuktikan melalui hasil validasi ahli yang menunjukkan kategori layak (78,5%), respons mahasiswa yang positif (79%), serta peningkatan signifikan skor literasi statistika setelah penggunaan e-modul. Temuan ini mengimplikasikan bahwa integrasi CBL dan hypermedia dapat dijadikan alternatif strategi pembelajaran yang lebih interaktif dan kontekstual untuk memperkuat literasi statistika. Model ini direkomendasikan untuk diadopsi dalam pengembangan media pembelajaran digital pada mata kuliah statistik dan bidang serupa yang menuntut keterampilan analisis data.]]>
