Science will be growing, so produced results that are
beneficial to humans. So,
what's the importance of science. Like
a mighty tree, which will be pierced in to the center of the earth, branches
twigs cover the corners of the horizon and the high clouds to reach even the
sky. But
since emerging from the ground "tree" that has manifested itself two
main stem, so that all the branches and twigs "tree" that grows from
both the main stem. Both
the main stem is a Natural Sciences and Social Sciences.
Natural Sciences in accordance with its name, investigating the state of nature and its contents. Natural sciences, earth sciences, mathematics, chemistry, etc. are examples of Natural Sciences. While the Social Sciences made man and society as a conversation. Within the scope of the social sciences, there exists Social sciences, Law, Economics, Religion, etc.
On the other hand science is divided into 2, namely:
1. Pure science
Pure science and served untui further enhance the preservation of life and the development of science itself.
2. Applied Science Applied science useful to apply in your life and the lives of everyday people
Examples of both these sciences such as Sosiolologi Sosiatri as pure science and applied science, psychology as a pure science and applied science Psychiatry. And some other branch of science that does not have a specific name for pure science and science that belongs to its application as Sociology and Psychology. Economics, for example, the parts named Pure Economics or Economic Theory and Applied Economics.
Subjects of Economics as part of the social sciences and the second is the first human bodies that are involved in economic activities, such as shops, companies, finance departments, consumer organizations, etc.. The object of economics is the means and the actions taken by the man in the allocation of existing resources.
Economics as a part of the Social Sciences dubbed as The Queen of the Sosicial Science (maharani social sciences) since economics is one of the social sciences using quantitative methods in the analysis-analysis.
Behind lies the kuantititif method of qualitative methods. As an example of these methods are as follows: a qualitative analysis can only state: "if the price goes up the number of items purchased something society will be reduced", whereas an analysis using quantitative methods dat ynag states: "if the price goes up by a few dollars amount purchased goods decreased by so many people ".
Economics have two kinds of main tools for analysis are:
1. Methods of induction and deduction
This method is widely used in the analysis of qualitative analysis, quantitative analysis also needs it though. Induction method is a method of inquiry, in which the particulars concluded matters of a general nature. Example of the division of society into castes ketatseperti sitem contained in Hindu religion in India is the cause inhibition of the rate of economic growth, as well as control over land rights to the Christian church groups in Europe before the revolution by Martin Luther, Protestants have also curtailed economic growth
2. Mathematics and statistics
Math: mathematical economics in particular. Math can be formulated with the applicable functions among variables (variables) economy.
Example: In the economic theory: The demand for a product is the manifestation of the relationship between the price of goods TSB (P) by the number of items they will be (Q) which purchased the community at various price levels. Can formulate a mathematical function of two variables that form the price (P) and the number of goods (Q).
Ill all the principles of the science of mathematics applied in reviewing this ekonomi.Dalam mathematics devoted to economics rather than vice versa. Negative values are not used in mathematics in economics.
Statistics is a continuation of the method of induction, deduction and mathematics. Dilasanakan statistics by collecting data terdpt in the real world. Statistics is closely connected with the real world
Both of these tools (mathematics & Statistics) part of the science has been regarded as the main tool for solving economic problems. Mathematics & Statistics together with pure economic theory both of them are members of a so-called economics Econometrics.
Derived from the Economics Econometrics (Economics) and Metric (measurement / measuremen). Econometrics means: The method of measurement in economics
Economical symptoms are: all events, fact, event, as well as human behavior that have economic value.
Example: Inflation (symptoms of excessive money supply in the community)
Poverty (national and symptoms of declining revenues per capita income), etc.
Among the symptoms are mutual economic relations. The relationship between economic symptoms can be classified into two, namely:
• The causality (casual relationship): which one is the cause of the symptoms are the other symptoms as a result.
Example: natural disasters and crop yields
Cause and effect
• Functional Relationship : Symptom-contained economic gajala influence.
Example: P & Q were purchased
If P as an independent variable and Q as the dependent variable if P then Q will climb down.
If Q as the independent variable and P as the dependent variable if Q then P rose up
Assumption / critical assumption in terms of the degree of truth of economics.
Economics benefits:
1. Individual
2. The business world
3. Government
