代写assignment:数据收集方法

“面试可以被定义为面对面的语言交流,在这种交流中,一个人,即面试官,试图从另一个或几个人那里获得信息或表达意见或信念。”这里采用的是访谈法。Michael Dunn在描述访谈的优势时认为,访谈法是最适合填补知识空白的方法,而其他方法,如观察或调查数据收集,可能无法完成。将这一点应用到当前的研究背景中,访谈法比其他任何方法都更有用。为了查明这里的粮食服务与空间居民之间的关系,可以寻求次级研究数据。然而,次要研究数据很少,而且它们可能并不总是最新的或前沿的数据,例如直接专家可以获得的数据。其次,一种可以邮寄问卷的调查方法是行不通的,原因有二。首先,调查人员可能无法获得被调查者的充分关注和兴趣,因此无法收集到最多的信息。
其次,虽然采访者已经进行了大量的研究数据收集和分析,可能仍然是一个新手在该领域。因此,面试官可能无法准确地找到一个主题或概念来询问主题专家。邓恩认为,意义和经验的多样性只能在采访中获得。由于作为主要研究人员,我已经收集了该学科的辅助数据,现在需要该学科的原始数据。次级数据、研究人员的意见以及更多的信息往往是重叠的,而收集到的初级数据将使人们对这个问题有一个更新鲜、更及时的了解。在开放式和封闭式问题的背景下,这里使用的方法是开放式问题。开放式问题将使主题专家对问题进行更多的讨论,而不会限制他们。此外,由于问题是提前发送的,他们会准备好谈论这个主题,所以在这里收集数据的最好方法是听、记录和提示如果必要的话。

“An interview can be defined as a face to face verbal interchange in which one person, the interviewer, attempts to elicit information or expressions of opinion or belief from another person or persons”. The interviewing method was followed here. Michael Dunn in describing the strengths of interview argues that interview method is the most suited method to fill in a gap in knowledge that other methods such as observation or survey data collection might not be able to fulfill. Applying this to the current research context, the interview method is more useful than any other. For identifying relationships between food services here and for the inhabitants in space, secondary research data could have been sought. However, secondary research data are minimal and they might not always be current or cutting edge data such as that would be available with the direct experts. Secondly, a survey method where a questionnaire can be mailed out would not have worked for two reasons. Primarily, the investigator might not have been able to gain the full attention and the interest of the interviewee, so maximum information cannot be collected.
Secondly, although, the interviewer has conducted much research data collection and analysis, might still be a novice in the field. So the interviewer might not be able to exactly pinpoint a theme or concept to query to the subject matter experts. Dunn argues that diversity of meaning and experiences can be obtained only in the interview. Since as the main researcher, I have already collected the secondary data on the subject, I now need primary data on the subject. Secondary data, researcher opinions and more are often overlapping and primary data collected would gave a fresher, more current insight into the problem. In the context of open ended versus closed ended questions, the approach used here is an open ended questioning. An open ended question will enable the subject matter expert to talk more on the questions and will not restrain them. Also since the questions are sent in advance, they would have prepared to talk about the subject, so the best thing to do in data collection here is to listen, record and prompt if necessary.
