双极等级工具(Bipolar rating instruments)用来测量人们对产品的情感观点。这种方法的常用和典型代表就是分为5,7和9这三种等级级别的等级量表(RatingScales),其中的数字代表了等级级别的数目(例如,‘5’表示总共有5种等级级别)。然而到目前很少有文献关注等级量表的最佳的级别数目问题。这里对这一问题进行了初步研究,尤其是针对这样的三种等级量表(S5,S7,S9),通过实验来给出了答案;研究表明,由于其高可靠性S最为适合。

Bipolar rating instruments are used to measure people’s feelings about the product. Commonly used and typical representatives of this method are divided into three grades of 5, 7 and 9 rating scales (RatingScales), where the number represents the level of the number of levels (for example, ’5’ means a total of five levels level). However, until now, there has been little question about the optimal level of the rating scale. Here is a preliminary study of this issue, especially for such three grades of scale (S5, S7, S9), the experiment gives the answer; research shows that due to its high reliability S is the most suitable.
