Going through the literature acquaints you with the methodologies that have been used by others
to find answers to research questions similar to the one you are investigating. A literature review
tells you if others have used procedures and methods similar to the ones that you are proposing,
which procedures and methods have worked well for them, and what problems they have
encountered. By becoming aware of any problems and pitfalls, you will be better positioned to
select a methodology that is capable of providing valid answers to your research questions. This
will increase your confidence in the methodology you plan to use and will equip you to defend
its use.
