What is research method? As a matter of fact, according to Saundra et al. (2003), the term method in the entire research process or project can be considered as tool or technique which help researcher obtain, collect and analyze data or different types of information. To be more specific, Saundra et al. (2003) point out that in order to fulfill different research projects and objectives, couples of methods have to be properly utilized, in this case, these approaches usually include questionnaire, observation and interviews. What is the nature of research? Saundra et al. (2003) argued that the genuine research should be defined as a project that the outcomes or objectives can be obtained and achieved in a systematic manner. Ghauri and Gronhaug (2002) discussed that in the process of conducting a research, there are two phases that have to be focused. The first is the research itself should be systematically designed and the second is the research objectives have to be clearly defined. Also, Saundra et al. (2003) stressed that in a well-structured research, each research method has to be carefully explained so as to be better implemented in the data collection process. In addition to justifying the different research methods, Ghauri and Gronhaug (2002) mentioned that the relevant problem, error and limitation that emerge in each method application need to be discussed as well.…
