Research is “the systematic and creative effort undertaken to add to the existing stock of knowledge”. It usually involves the collection, organization, and evaluation of data to improve knowledge of a subject or area. A research project can also be an extension of past research in the area. It should not be confused with study abroad, which is the systematic study of a foreign country, as in this case the efforts are directed towards learning the language and culture of that country. The two areas are often used interchangeably; however research is sometimes considered the process of learning about another culture.
