Focus group 群面(应该不是群面)

后面有一篇讲Focus group的，这个大家商科的学过HR应该都知道的。文章讲了Focus Group的3个limitations，第一个是说Focus Group以点概面，不能代表整体情况。第二个说Focus Group里的人更倾向于oral, written description之类的，第三个忘了。。。最后一段其实也在说FG的另外的局限

A focus group is a form of qualitative research in which a group of people are asked about their attitude towards a product, service, concept, advertisement, idea, or packaging. Questions are asked in an interactive group setting where participants are free to talk with other group members.

Ernest Dichter originated the idea of having a "group therapy" for products and this process is what became known as a focus group.^[1]

However, focus groups also have disadvantages: The researcher has less control over a group than a one-on-one interview, and thus time can be lost on issues irrelevant to the topic; the data are tough to analyze because the talking is in reaction to the comments of other group members; observers/ moderators need to be highly trained, and groups are quite variable and can be tough to get together. (Ibid.) Moreover, the number of members of a focus group is not large enough to be a representative sample of a population; thus, the data obtained from the groups is not necessarily representative of the whole population, unlike in opinion polls.

A fundamental difficulty with focus groups (and other forms of qualitative research) is the issue of observer dependency: the results obtained are influenced by the researcher, raising questions of validity. The issue evokes associations with Heisenberg’s famous Uncertainty Principle. As Heisenberg said, "What we observe is not nature itself, but nature exposed to our method of questioning." Indeed, the design of the focus group study (e.g. respondent selection, the questions asked, how they are phrased, how they are posed, in what setting, by whom, and so on) affects the answers obtained from respondents. In focus groups, researchers are not detached observers but always participants. Researchers must take this into account when making their analysis (Based on: Tjaco H. Walvis (2003), “Avoiding advertising research disaster: Advertising and the uncertainty principle”, Journal of Brand Management, Vol. 10, No. 6, pp. 403-409).

Douglas Rushkoff^[2] argues that focus groups are often useless, and frequently cause more trouble than they are intended to solve, with focus groups often aiming to please rather than offering their own opinions or evaluations, and with data often cherry picked to support a foregone conclusion. Rushkoff cites the disastrous introduction of New Coke in the 1980s as a vivid example of focus group analysis gone bad.

LZ告诉我们找的方法，我们也好找。。不然。。没有头绪。

我就是用google啊,然后输入关键词,大家都会的,接着就大海里捞啊捞.

不过捞了这几篇下来我发现好像在wikipedia里面都能找到，大家试试看

wiki常常被封掉，还是楼主厉害， 跪拜！！！

封wiki？？为什么？好像没有封它的理由嘛。

我在北美，所以可能是因为这个能用？
