📚 US Presidency: Mathematical Perspectives on Elections and Power | 美国总统制：选举与权力的数学视角
The US Presidency is often studied through political and historical lenses, but mathematics offers a powerful framework for understanding presidential elections, approval ratings, and campaign strategy. This revision article connects key concepts from Edexcel A-Level Mathematics such as the binomial distribution, normal approximation, confidence intervals, hypothesis testing, and conditional probability to the mechanics of the US presidential system. By modelling voter behaviour and electoral structures, students can see how abstract statistical tools apply to real-world political contests.
美国总统制通常从政治和历史角度研究，但数学为理解总统选举、支持率和竞选策略提供了强有力的框架。这篇复习文章将 Edexcel A-Level 数学中的关键概念——如二项分布、正态近似、置信区间、假设检验和条件概率——与美国总统制的运作机制联系起来。通过对选民行为和选举结构进行建模，学生可以看到抽象的统计工具如何应用于真实的政治竞争。
1. The US Presidency and Quantitative Reasoning | 美国总统制与定量推理
The President of the United States is elected every four years through an indirect system known as the Electoral College. To win, a candidate must receive at least 270 of the 538 electoral votes. Mathematical reasoning helps us analyse whether the system is fair, how likely a candidate is to win given polling data, and how campaigns should
