What Are Preference Ballots and Preference Schedules?

1. What Are Preference Ballots and Preference Schedules?

Preference voting is not the most commonly used form of voting in the United States. Even so, it is very interesting and has its place in our society. This lesson reviews preference ballots and schedules.

The Plurality Method in Elections

2. 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.

The Borda Count Method in Elections

3. 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.

The Plurality-with-Elimination Election Method

4. 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.

The Pairwise Comparison Method in Elections

5. 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.

Ranking Candidates: Recursive & Extended Ranking Methods

6. 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.

Arrow's Impossibility Theorem & Its Use in Voting

7. Arrow's Impossibility Theorem & Its Use in Voting

This lesson reviews Arrow's Impossibility Theorem, which states that there is no preferential voting method that adheres to reasonable fairness principles. An example is used to illustrate his theorem.

Voting Age History

8. Voting Age History

The voting age in America is set at 18, but how was this decision made? The history of the voting age reveals a deep debate about federal authority dating back to the drafting of the US Constitution. We'll explore this history and see how the debate changed over time.
