e interviewing or sending questionnaire by hand delivery instead of web-based communication might bring more efficiency for the research outcome.
调查中出现的限制可能会影响研究结果。在这项研究中，有三个可能的核心局限性，即数据收集方法、受访者给出的答案和问卷调查。首先，选定的数据收集方法是限制之一。Schaefer和Dillman一致认为，尽管万维网技术在调查方法中更为普遍，但它仍然存在一些缺点。然而，由于这项研究侧重于在线购买行为，仅通过在线收集数据可能会导致偏见。在很大程度上，向被调查者发送在线问卷可以缩小样本群体的范围。很明显，回答在线问卷的人似乎是生活方式已经在线的受访者。因此，它可能会对偏见产生影响，因为它消除了从其他没有或不想上网的人那里收集数据的机会。因此，在这种情况下，另一种数据收集方法，如面对面访谈或手工发送问卷，而不是基于网络的交流，可能会提高研究结果的效率。
Secondly, respondents might be a cause of incorrect answers. For one thing, certain respondents are in a hurry, so they might choose the wrong choices by accident, and some of them might in an unstable emotion, then the questionnaires are completed wrongly. Apart from these, there are still having other factors like unreliability of the respondents, their misunderstanding and their prejudice toward online purchasing behavior. Moreover, they may answer the questions roughly without consideration, therefore, the answers that come from these kinds of respondents do not elicit from the real opinion or experience.
其次，受访者可能是错误答案的原因。首先，某些受访者很匆忙，因此他们可能会意外地选择错误的选择，其中一些人可能情绪不稳定，然后问卷填写错误。除此之外，还有其他因素，如受访者的不可靠性、他们对网络购买行为的误解和偏见。此外，他们可能会在没有考虑的情况下粗略地回答问题，因此，这类受访者的答案并不是从真实的意见或经验中得出的。
Lastly, the questionnaire itself could affect the validity and reliability of the research. It is generally agreed that the close-ended questionnaire is provide less time consuming and ease of use for respondents. On the other side, the multiple choices presented in the questionnaires might not perfectly match to their exact opinions. Accordingly, respondents had to choose one choice that is not an answer they want because they cannot find the answer that actually suits their points of view.
最后，问卷本身可能会影响研究的有效性和可靠性。人们普遍认为，封闭式问卷为受访者提供了更少的时间和易用性。另一方面，问卷中的多项选择可能与他们的确切意见不完全一致。因此，受访者不得不选择一个不是他们想要的答案，因为他们找不到真正适合自己观点的答案。
3.10 Summary 总结
This chapter focused on the research design that appropriate with the research aim and objectives. Several different methods was used as to collect the data both primary and secondary data. The quantitative research is both launched through web hosting site and used of electronic mail. Furthermore, the use of pilot test is to guarantee that the questions are capable to carry out in actual research, to evaluate reliability as a consequence of Cronbach alpha technique and to evaluate proper samples size from statistic formula. The next chapter will analyze data from data collection to test hypotheses from the designed framework.
留学生毕业论文关于本章着重论述了与研究目的相适应的研究设计。使用了几种不同的方法来收集主要和次要数据。定量研究既通过网站发起，也使用电子邮件。此外，使用中试是为了保证问题能够在实际研究中进行，评估Cronbachα技术的可靠性，并根据统计公式评估适当的样本量。这篇留学生毕业论文会在下一章将分析数据收集中的数据，以检验设计框架中的假设。本站提供各国各专业留学生毕业论文写作指导服务，如有需要可咨询本平台。
