What is the course about?

GCNU1017 begins with an introduction to the way in which statistical information can be used to interpret and affect election phenomena and other everyday issues. Students will learn a number of election systems and address the problem of finding the best decision-making procedures. Moreover, a variety of possible methods of electing our future Chief Executive are investigated (although we cannot promise you that he or she will ever be elected through universal suffrage). After equipping you with the knowledge of different electoral systems, we then introduce you to the weighted voting system, in which voters may be treated unequally. Next, the course turns to an investigation of a number of simplified but real-life cases, such as the distribution of seats in the Legislative Council of Hong Kong. Finally, we address the mathematically well-known cake-cutting problem, which is formally known as the fairness problem. You will find the answer to many fairness-related questions in this course.
