The scholarly or systematic investigation about a specific subject is called research. It is a detailed inquiry about a specific problem or a concern employing scientific method. There are different types of research in several subject fields. Usually, a research will start from a certain question based on observation. A hypothesis is made and will soon be verified after the research is being conducted. Researches must be conducted with objective purposes and must be bias-free in order not to defeat the purpose of research that is to educate and to inform the public.
