Suppose students at our school are voting for the sixth-grade field trip. The following is a list of options for your class to vote on.
Option 1: Baseball Game
Option 2: Amusement Park
Option 3: Museum
Option 4: Dance at School
| options | vote 1 | |||
|---|---|---|---|---|
| baseball game | ||||
| amusement park | ||||
| museum | ||||
| dance |
What percentage of voters are satisfied with these results (voted for the winning option)? What percentage were not satisfied?
Compare the satisfaction results for the plurality voting rule and the runoff rule. Did one produce satisfactory results for more people than the other?
Let’s analyze a different election.
In another class, there are four clubs. They plan to use the ranked-voting system. Everyone in each club agrees to make the same choice for the field trip for each round of voting. That means that everyone’s choices are set by their first vote. The table shows their choices.
Figure out which option won the election by answering these questions.
