Economics relies on a contrast between positive assertions, which describe the world as it is, and normative claims, which describe how the world should be, in order to characterize economic behavior as it actually occurs.
What are economics?
Economics is the study of scarcity and how it impacts a wide range of complex societal challenges, including the use of resources, the creation of goods and services, the increase in productivity and welfare through time, and many other complex problems. Economic analysis' fundamental purpose is to examine individuals. It seeks to make clear the motivations underlying people's choices, deeds, and reactions to successes or failures. Sociological, psychological, historical, and psychological topics are all included in economics research.
What is the difference between positive economics and normative economics?
Different economic phenomena are described and explained by positive economics. The goal of normative economics is to determine what the economy "should" or "ought" to be. Normative economics is founded on value judgments, as opposed to positive economics, which is based on truth and cannot be approved or disapproved.

Answer:
constant, measured variable, manipulated variable.

Explanation:
In the past, learners were required to achieve at least 50% in four specific designated subjects that were the same nationwide. However, this was recently changed - the new requirements include attaining the same percentage in any four subjects that have 20 credits from a list of subjects.
This change has certain advantages and disadvantages. The advantage is that there will be more students with better percentages applying for various high education institutions as it should now be easier for them to pick subjects they are most confident in and that will be relevant for their further education. Their focus will also be on those most important subjects for them and their studies instead of on something they might not even need in their future career.
However, a disadvantage is that students might pick subjects they find easiest just to secure their place in a university. Those subjects ultimately might not provide them with needed strategies for thinking and learning that otherwise designated subjects might have. Furthermore, some higher education institutions might have their own lists of designated subjects and minimum entry requirements that might not be the same as the student's choices
