抽样调查中的数据分析_国际商务管理

  使用辅助数据来进行研究也是一个不错的方法。使用辅助数据最显著的优点就是它可以节省研究者的时间和投资。如果所需要的信息可以作为参考,研究人员可以简便的去图书馆或从网络上进行查找,这样就可以低成本的找到所需要的源代码。

  Research on secondary data is also a good method. The most significant advantages of secondary data are the time and money they save researcher. If the information being sought is available as secondary data, the researcher can simple go to the library or go online, locate the appropriate source or involve little cost.

  如果将很多相同的信息收集在同一个样本里面进行抽样调查,下面的几个步骤是必须要考虑的:数据采集方式的设计和处理、面对面采访人员的挑选和培训、抽样方案的设计,遗漏的数据收集和数据准确性的检查,对数据进行编码和分析。

  If the same information were to be collected in a sample survey, the following steps would have to be taken: data collection from designed and protested; field interviewing staff selected and trained; sampling plan devised; data gathered and then checked for accuracy and omissions; data coded and analyzed.

  With secondary data, the expenses incurred in collecting the data have already been paid by the original compiler of the information. Given the substantial amount of time and money at stake, we offer this advice: Do not bypass secondary data ( Gilbert A Churchill, Jr.&Tom J Brown, pp.163.2004).

  Among data collection techniques, documentation review is the method to quickly and accurately collect the existing information and historical information. “This method is to collect data through reviewing the formal company documents and reports about production, sales and finance.” (Saunders et al, pp. 104, 2006).In my opinion, this documentation review is good for us, because this method is easy to do and has few limits to the market environment. And we collect other historic data and information from this method.

  “Questionnaires are an inexpensive way to gather data and information from a potentially large number of respondents and often the only way to reach a number of reviewers large enough to allow statistically analysis of the results.” (Mason, pp. 72, 1996).This research method can collect comprehensive information. This method of questionnaire is widely used in market research, because it is a fast and easy way to collect consumer’s information. In addition, I am a student, so Document review and questionnaire methods are suitable for my research very much. I can go in many ways to implement my research.
