Final answer:
The statement 'It is wrong to cheat on exams at school' is a value proposition, expressing a moral judgement rather than a verifiable fact.
Step-by-step explanation:
The proposition 'It is wrong to cheat on exams at school' is an example of a value proposition. Unlike factual statements, which assert that something is the case, value propositions express a judgement about the worth, desirability, or correctness of something. The statement in question is not about a factual matter that can be empirically verified; rather, it expresses a moral judgment about the act of cheating.
When considering propositions, we can contrast factual statements, which can be proven true or false, with statements of value, which express an opinion or belief regarding something's merit. Moreover, this should not be confused with policy propositions, which advocate for a specific course of action or a set of guidelines to be followed.
