The CBSE Class 12 Data Science question paper and marking scheme are structured to assess students’ competence in one of today’s most dynamic and in-demand fields. The paper evaluates both theoretical knowledge and practical application skills across areas such as data collection, preprocessing, analysis, visualization, and interpretation. Core topics include statistical methods, machine learning algorithms, and Python programming for data handling and analysis.
The marking scheme offers a clear distribution of marks, outlining the weightage for multiple-choice, short-answer, long-answer, and practical coding problems. Students are expected to apply their understanding to tasks such as data cleaning, exploratory data analysis, and model evaluation. The practical component emphasizes writing effective Python programs to analyze datasets, generate visualizations, and extract meaningful insights, with a focus on accuracy and problem-solving.
This structured question paper and marking scheme help students sharpen their analytical thinking, computational skills, and practical application of data science concepts. It also provides a strong foundation for those aspiring to pursue advanced studies or careers in data analytics, machine learning, artificial intelligence, and related domains.
