研究方法是研究研究的重要组成部分之一，它对研究目标的成功实现起着至关重要的作用。研究方法有助于根据研究课题的特点以及研究的要求选择最合适的研究工具和技术(Ramlow and Nusz, 2012)。对于这项特殊的研究，研究人员必须采用多种研究方法的结合。文献综述有助于了解所承担研究课题的基本思路。文献综述被认为是次要研究。此外，在文献综述中，也对前人的研究成果进行了综述，他们对相同主题的类似类型的研究进行了研究(Smyth and Skates, 2009)。在这个问题上，书籍、期刊文章和新闻文章都是有用的，它们提供了关于这一特定主题的前研究者的研究的足够的知识。除此之外，网络期刊、网站内容、废旧物品、网络新闻文章以及网络图书也都是非常有用的，为研究提供了有效的信息。这些资料有助于了解前人的研究情况、前人的研究方法和研究结果。除此之外，从这些材料中，本研究的研究人员可以认识到研究人员在类似主题上进行研究的局限性(Thakur and Chandel, 2013)。文献综述有助于发现与本研究相关的问题，并有助于制定本研究的目标。此外，文献综述对研究问题的提出也有一定的帮助，并在这些研究问题的基础上开展了研究工作。从二次研究中，可以收集到二次数据。
The research methodology is one of the most important parts of the research study, and it plays the major role in the successful accomplishment of the research objectives of a research study. The research methodology helps in selecting the most appropriate research tools and techniques according to the characteristics of the research topic as well as the requirements for the research study (Ramlow and Nusz, 2012). For this particular research study, the researchers have to apply a combination of research methodologies. The literature reviews are useful in acquiring the basic ideas about the undertaken research topic. The literature reviews are considered as the secondary research. Moreover, in the literature review, the works of previous researchers have been reviewed, who conducted research on the similar types of research with the same topic (Smyth and Skates, 2009). In this matter, books, journal articles, and news articles are useful that provide adequate knowledge about the research of the former researchers on this particular subject. Besides this, the online journals, website contents, scraps, and online news articles along with online books are also useful and provide effective information for the research study. These materials help in knowing about the research of the former researchers, the method adopted by the former researchers and the result of their research. Apart from this, from these materials, the researchers of this particular research can recognize the limitations of the research conducted by the researchers on the similar topics (Thakur and Chandel, 2013). The literature reviews help in detecting the issues regarding the research as well as in formulating the objectives of the research. Besides this, the literature reviews are useful in making the research questions, and based on these research questions, the research work is carried out. From the secondary research, the secondary data can be collected.
