This document discusses bunking lectures and uses a Pareto chart to analyze the key factors responsible. It introduces the Pareto principle, which states that a small number of causes are responsible for the majority of problems. A survey found that 80% of reasons for bunking lectures were to attend coaching classes, dislike a subject, peer pressure, course content available elsewhere, and issues with the teacher. The document defines a Pareto chart as a type of bar graph used to visualize important situations or causes. Analyzing the major factors through a Pareto chart can help address the biggest problems and improve outcomes.
