About This Chapter
Mathematical Methods for Elections - Chapter Summary and Learning Objectives
An enormous amount of money is spent during elections. The outcome means a lot to people, and so can the subject of this chapter, which explains the math behind figuring out who the winning candidate is. Our instructors use short videos for presenting their lessons, and they supply a quiz to take at the end of each lesson for self-assessment. For any needed re-study, you can use the video transcript of the lesson or a keyword-based timeline tool to return to the specific section you want to watch again. At chapter's end, you will be educated on:
- Understanding the plurality method in elections
- Using the Borda count method in elections
- Implementing the plurality-with-elimination election method
- Working with the pairwise comparison method in elections
- Ranking candidates using recursive and extended ranking methods
|The Plurality Method in Elections||Find out how in the U.S., there is more to victory than the one with the most votes wins.|
|The Borda Count Method in Elections||Analyze the Borda count method of determining a winner.|
|The Plurality-with-Elimination Election Method||Examine how the run-off works in plurality-with-elimination method of elections.|
|The Pairwise Comparison Method in Elections||Take a look at how the pairwise method compares candidates head-to-head.|
|Ranking Candidates: Recursive & Extended Ranking Methods||See who would come in second and third using recursive and extended ranking methods.|
1. The Plurality Method in Elections
The plurality method of voting is the most common form of voting in the U.S. The basic principle is that the candidate with the most votes wins; however, there really is more to it than that.
2. The Borda Count Method in Elections
Have you ever wondered how a winner is determined when you must rank the choices in a voting scenario? This lesson covers the Borda count method of determining a winner in preferential elections.
3. The Plurality-with-Elimination Election Method
When a run-off is needed in an election, do all the voters have to return to the polls? In the plurality with elimination election method, the run-off can happen instantly. This lesson explains how.
4. The Pairwise Comparison Method in Elections
The pairwise comparison method in elections is a method of comparing candidates to each other in head-to-head contests. This lesson reviews the pairwise comparison method.
5. Ranking Candidates: Recursive & Extended Ranking Methods
If you have ever wondered who would come in second place in an election (or third or fourth), this lesson will give you two ways - the recursive and extended methods - to determine just that information.
