Introduction

In the realm of mathematics, particularly in the field of social choice theory, voter preference tables play a crucial role in understanding how individuals make decisions. A voter preference table is a matrix that represents the preferences of voters for different candidates. In this article, we will delve into the analysis of a given voter preference table and explore the mathematical concepts that underlie it.

Understanding the Voter Preference Table

The voter preference table provided is a 5x5 matrix, where each row represents a voter and each column represents a candidate. The entries in the table are the preferences of each voter for each candidate. For instance, in the first row, the voter prefers candidate A over candidate B, candidate B over candidate C, and so on.

	21	12	6	47	9
1st	A	B	A	D	A
2nd	D	C	C	C	B
3rd	B	D	D	A	D

Majority Judgment Method

One of the methods used to analyze voter preference tables is the Majority Judgment method. This method involves assigning a score to each candidate based on the number of voters who prefer them in each position. The candidate with the highest score is declared the winner.

To apply the Majority Judgment method, we need to calculate the scores for each candidate. We can do this by counting the number of voters who prefer each candidate in each position.

Calculating Scores

Let's calculate the scores for each candidate.

Candidate A:
- 1st position: 3 voters (21, 6, 9)
- 2nd position: 1 voter (47)
- 3rd position: 1 voter (12) Total score: 5
Candidate B:
- 1st position: 1 voter (12)
- 2nd position: 1 voter (21)
- 3rd position: 2 voters (6, 9) Total score: 4
Candidate C:
- 1st position: 0 voters
- 2nd position: 3 voters (12, 6, 47)
- 3rd position: 0 voters Total score: 3
Candidate D:
- 1st position: 1 voter (47)
- 2nd position: 2 voters (21, 9)
- 3rd position: 1 voter (6) Total score: 4

Determining the Winner

Based on the scores calculated above, we can determine the winner of the election. The candidate with the highest score is declared the winner.

In this case, Candidate A has the highest score with a total of 5 points. Therefore, Candidate A is declared the winner of the election.

Conclusion

In conclusion, the voter preference table analysis using the Majority Judgment method provides a clear understanding of how individuals make decisions. By calculating the scores for each candidate, we can determine the winner of the election. This method is useful in understanding the preferences of voters and can be applied in various real-world scenarios.
