Another form of graph is cross-section graphs. Cross-section graphs have the advantage of simplicity. You can gather the information quickly by just looking at a cross-section graph. It is usually composed of cross-bars, however, you can use lines or dots instead of bars. There are several different relationships between two variables. They can be inverse relationship, positive relationship, or no relationship.
As mentioned before, economic issues arise when the limited resources do not meet our daily requirements. Economy allows us to find the most effective way to utilize our resources. Limited resources include: labour, land, capital and entrepreneurships. Labour is the work one can do to produce goods and services. Land is what we have for granted, such as air, water and mineral underneath. Capital is the projects that we produce to simplify the production of our goods and services, such as dams, and highways. Human capital is also a kind of capital, they are the knowledge that we possess to do things more effectively and smart. Our wants are unlimited, if we want to have an easier and better life, we have to improve ourselves and make our limited resources catch up with our soaring wants!!
