Exploring the facts is called research. The method which is used for exploring the facts is called the Scientific Method.
Science is an organization of facts which is the result of hard work for long period of research. Man has been trying to search out the secrets of this universe. The concept of curiosity is natural in man. He thinks on the events and their causes happening around him. He has been thinking to control the causes of the events. By this way, he has been trying to control the events. It was all due to the store of knowledge available to him. By the application of the scientific method and theoretical knowledge, he was able to find out causes of the phenomena and then control the events. He was able to predict for the future events.
The only method of exploring facts is the method of scientific observation. Thus he collected information and found relationship among them. He came to a conclusion as why such a phenomemon occurs and in what conditions? The experiements made man, in this way, provided him theoretical knowledge which became theories and laws of science.
We see that the slum areas and the dirty houses are the origion of tuberclosis along with insufficient and impure food available to them. Worries and tensions added being the major factors of the phenomenon (T.B.). These factors are responsible for occurrence of this phenomenon (T.B.). It was all due to the exploration of facts.
The facts which we collect after research are inter-related togeth at a certain point. The Inductive method of logic provides us these facts after research. Relationship among them provides knowledge to the scientist which becomes a part of Science.
It means that organization among facts is called theory and hence, theory is a scientific knowledge.
The man is researcher who tries to discover facts after research. Research is done in a laboratory. In Sociology, social group is our laboratory in which we study the phenomenon. For example we study illiteracy in a village. Then village is our laboratory and Illiteracy is our phenomenon. The man who conducts research is a researcher. The method applied during research is called the Scientific Method. It includes deductive and inductive methods of logic. The researcher is a person who is neutral in his study and free from his personal values. He is expert in applying the Scientific Method. He is unbiased in the study of the problem.
