The type of methodology adopted in a study is influenced by the nature of the reaches and the topic that is being studied. When a researcher is deicing on the methodology to adopt for a particular study, he/she must think of how the research questions and the hypotheses are going to be addressed. The methodology should clearly describe how the study can be replicated in another situation. Every stage of the process must be explained and justified.
Krueger (2008) describes secondary research is an approach to research in which existing information is summarized, collated, and synthesized. In secondary research, the researcher uses information and data that had been collected by other researchers. A variety of sources are used in secondary research. They include letters, documents, previous primary studies, books, journals, diaries, autobiographies, and archival records (Saunders et al., 2009). Magazines articles, marketing reports, and data from company websites can also be used in secondary studies. There are several advantages of using secondary research. First, it saves the researcher a lot of times. In this approach, the researcher does not have to go to the field to collect primary data. On the contrary, he uses information that is already documented. This allows him to spend more time in analyzing the data (Saunders et al., 2009). Secondly, secondary research allows the researcher to approach a subject or topic of study from different perspectives. The use of a variety of sources to collect data allows the researcher to understand and evaluate the perspectives of another researcher on the topic of study. Secondary research also gives the researcher general background information on the topic of study.
