1、Chapter NineMeasurement And Scaling:Non-comparative Scaling Techniques第九章测量与量表：非比较量表技术赵冬阳 讲师经济与管理学院西南财经大学 市场营销博士生e-mail: sunny_Chapter Objectives学习目标1.描述非比较量表技术，区分连续链表技术和分项评分量表，并解释Likert量表、语义差别量表和斯坦普尔量表2.讨论在构造分项评分量表时所涉及的有关量表类别数目、平衡量表与非平衡量表、奇偶数类别、强制与非强制性选择、语言描述程度及量表的物理形式等决策问题3.讨论评价量表时所用的标准，并解释如何评估信度、

2、效度和可推论性4.讨论在国际背景下执行非比较量表时所要考虑的问题5.理解在构造非比较量表时所涉及的伦理道德问题6.讨论因特网和计算执行连续评分量表和分项评分量表时的应用2011/2/17ZHAODongyang Panzhihua University2Chapter Outline学习内容l概要l非比较量表技术 l连续评分量表 l分项评分量表lLikert 量表l语义差异量表l斯坦普尔量表2011/2/17ZHAODongyang Panzhihua University3Chapter Outline学习内容l非比较分项评分决策 l量表类别的数目l平衡量表与非平衡量表l类别的奇偶数l强制性

4、分标准，不对被评价的物体与另一物体或一些指定的标准进行比较。调查对象一次只评估一个对象，因此非比较量表经常被单胞量表。非比较量表由连续评分量表和分项评分量表组成2011/2/17ZHAODongyang Panzhihua University6Continuous Rating Scale连续评分量表Respondents rate the objects by placing a mark at the appropriate position on a line that runs from one extreme of the criterion variable to the oth

5、er.连续评分量表也称为图示评分量表。调查对象通过在一条直线上的适当位置做出标记为物体评分。The form of the continuous scale may vary considerably. 连续量表的形式可能变化相当大。 How would you rate Sears as a department store? 就百货商店而言，你将如何斯尔斯评分？Version 1 形式1Probably the worst - - - - - - -I - - - - - - - - - - - - - - - - - - - - - - Probably the best 可能最差 -

8、 400 respondents is presented with TV or radio spots or advertising copy. The measuring device consists of a dial that contains a 100-point range. Each participant is given a dial and instructed to continuously record his or her reaction to the material being tested. As the respondents turn the dial

9、s, the information is fed to a computer, which tabulates second-by-second response profiles. As the results are recorded by the computer, they are superimposed on a video screen, enabling the researcher to view the respondents scores immediately. The responses are also stored in a permanent data fil

When arriving at a total score, the categories assigned to the negative statements by the respondents should be scored by reversing the scale.利克特量表需要调查对象对关于刺激物体的一系列陈述中的每一
