    Evaluation tends to be less complicated than research.  Many people engage in informal evaluation on a daily basis.  Formal evaluation and research processes are "systematic and rigorous," but they differ in that evaluation focuses on a program, determines value, and happens in real time, while research focuses on populations and stays value-free.

    There are a variety of purposes and approaches to research and evaluation.  Research pursues answers to questions to create new knowledge.  Evaluation uses data to guide decision making, determine if and how a program is meeting its goal and objectives, and establishes long-term effects of a program.

    Evaluation and research are generally seen as two separate and mutually exclusive classifications.  This is not always the case, as there may be some overlap between the two.  Evaluation may also be viewed as a subset of research, and vice versa.
