t of time for study the data to figure out the key findings (Jones, 1984).
The second large advantage of utilizing secondary data is that almost all kinds of existing data could be found. Some data is very difficult for individual to collect, such as national scale data, population and so on (Bayer and Servan-Schreiber, 2011). However, those data is not necessary for individual researchers to collect by themselves; government already collects the data. Moreover, as there are abundant data, the researcher could see the trend by analysis of secondary data.
The third major advantage of utilizing secondary data is that the data collection process is often led by professional organization such as university professors, research institute. So the data is well collected by professional methods.
For example, a lot of federal data sets are often done by staff members, who are very professional for data collecting. It’s because the data collectors are professional in certain tasks and have a lot of years of experiences in the subject. Such data is very difficult to collected by individual researchers or smaller research team, as they don’t have such professional experts.
3.1.3Disadvantage Secondary Data Alalysis
The first main disadvantage of utilizing secondary data is that it could not specifically answer the researcher’s research questions. In another word, it might not have been collected in the specific year, geographic area or specific industry, and thus it might not mostly suitable for answering the researcher’s questions (BOO and FROELICHER, 2012). The problem is that the data would be categorized differently than the researcher would have chosen. For example, only people aged above 30 were collected, meanwhile the researcher might need the data covering all ages.
The second main disadvantage to utilizing secondary data is that the researcher is not familiar with the data and how the data was collected. In consequence, when the researcher try to utilize the secondary data for answering his or her specific questions, the information of data might not fully suitable, either not sufficient to prove researchers’ viewpoint. Moreover, as the researchers didn’t involve in the progress of data collection, he or she would no well understand the link between the data and the questions (Murakami, 2007). So when utilizing those data, the researcher would slightly be misunderstanding about the data and his or her research questions.
3.2 The Approach of Case Study
3.2.1 Definition of Case Study
It is generally agreed that the method of case-study was firstly released to social science by Frederic Le Play in 1829 (Sorin‐Peters, 2004). A case study includes flat, in-depth, and detailed examination of a subject, as well as its relative conditions. Case studies are common used throughout popular works, nearly every one have the experiences of case studies. Case study is an effective and low cost way for figuring out key issues or finding out the answers to the specific questions. By conclusion and discuss, it could provide a framework for the answers and gradually reach to the research target. Case study is likely to be released in formal research venues, such as professional conferences, journals and professional books.
Case study is defined as a research method to investigate a phenomenon in realit
