Positive vs Normative Economics
Positive statements are normally used where we have factual evidence and normative statements are more commonly used when everyone may not agree on a particular topic.
Normative Statements
These are value judgments that include an opinion (they are also called subjective statements).
Example: Canadians should pay less in tuition.
Positive Statements
These describe the world as it is and do not include opinions (also called objective statements).
Example: Students in North America on average pay $9000 in tuition fees.
