Understanding data interpretation strengthens answers in the UPSC exams as it allows candidates to analyze and present evidence-based arguments effectively. Familiarity with graphs, tables, and charts helps to identify trends and make informed decisions regarding policy implications. Practicing data-related questions enhances analytical skills, which are essential for sections in both the mains and interview stages. Using data to back up claims in written answers adds credibility and depth. This skill also supports better performance in subjects like economics and social issues, where quantitative data is frequently applicable.
