Research - Systematic study undertaken to increase knowledge

"Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization, and analysis of information to increase understanding of a topic or issue. A research project may be an expansion on past work in the field. Research projects can be used to develop further knowledge on a topic, or for education. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. - Wikipedia"
