Research in simple terms, refers to a search for knowledge. It is also known as a scientific and systematic search for information on particular topic or issue. It is also known as the art of scientific investigation. Several social scientists have defined research in different ways.
In the Encyclopedia of Social Sciences, D. Slesinger and M. Stephension (1930) defined research as “the manipulation of things, concepts or symbols for the purpose of generalizing to extend, correct or verify knowledge, whether that knowledge aids in construction of theory or in practice of an art”.
