Why
do we do a literature review?
- To
see what has and has not been investigated.
- To
develop general explanations for observed variations
in a behavior or phenomenon.
-
To identify potential relationships between concepts
and to identify researchable hypotheses.
-
To learn how others have defined and measured
key concepts.
- To
identify data sources that other researchers have
used.
- To
develop alternative research projects.
- To
discover how a research project is related to
the work of others.
