Current Affairs Connections
New Education Policy 2020 introduces weighted assessment system
July 2020The National Education Policy 2020 emphasizes continuous and comprehensive evaluation with weighted assessment where different components like projects, assignments, and examinations carry different weights in final evaluation. This directly relates to weighted average calculations where students need to compute their overall performance based on different weightages assigned to various assessment components. Understanding weighted average becomes crucial for students to calculate their cumulative grades under the new system.
UPSC Angle: CSAT questions may incorporate scenarios from the new education system where candidates need to calculate weighted averages of student performance across different assessment components, making this concept highly relevant for current exam patterns.
COVID-19 vaccine efficacy calculations use weighted average methodology
March 2021During the COVID-19 pandemic, vaccine efficacy rates were calculated using weighted average methods where different age groups, comorbidity conditions, and demographic factors were given different weights based on sample sizes and risk factors. For instance, if a vaccine shows 95% efficacy in 1000 young adults and 85% efficacy in 500 elderly participants, the overall efficacy is calculated using weighted average: (1000×95 + 500×85)/(1000+500) = 91.67%. This real-world application demonstrates the practical importance of weighted average in public health decision-making.
UPSC Angle: CSAT may include questions based on health statistics, vaccine efficacy, or medical research data where candidates need to apply weighted average concepts to analyze combined results from different population groups or study samples.
