Final answer:
A plurality is when an option receives more votes than any other but not necessarily over half, while a majority is more than half. Hence, not every plurality is a majority.
Step-by-step explanation:
The statement 'Every value that is a plurality is also a majority' is false. A plurality refers to the condition when a choice receives more votes than any other, but not necessarily more than half of the votes. On the other hand, a majority means more than half of the votes. Therefore, it is possible for a plurality to exist without a majority, especially in situations with more than two options.
