A) Qualitative and quantitate analysis
B) Key words and databases to be used
C) Time frame and study design
D) Setting used in the study
B) Key words and databases to be used
When performing a search, the first thing that a researcher ought to investigate is what kind of database would they need to use, as well as what are the proper keywords to help in recognizing the research short articles. The keywords to be used may be complex, and the researcher should devote timein determining all the possible key words in advance.
