排序不仅是科学研究的常用方法,在现实生活中也有着广泛应用,但对于不同排序方法排序结果的比较却鲜有报道。本研究通过颜色偏好实验考察了对偶比较法、等级排列法和两极递进式排序法三种排序方法的稳定性和一致性等指标,并比较了三种方法的优劣。结果表明:三种排序方法在颜色偏好的判断作业中具有较高的稳定性和一致性,其中以对偶比较法的稳定性稍高;三种排序方法在稳定性、经济性、简便性、直观性和适用条件上各有优劣,文末就三种排序方法的应用提出了建议。
The widely used ranking methods are the paired comparison method, the rank-order method and the alternation ranking method. A color preference experiment was conducted to compare them in terms of psychometric characteristics and user reactions. We calculated Spearman' s correlation coefficient as the index of stability and Kendall coefficient of concordance as the index of consistency of each kind of ranking method for each subject. The results indicated four main findings. Firstly, no significant difference among the ranking methods was found. Secondly, stability correlation was influenced significantly by the experimental sequence. The time interval between the same ranking methods and the other embedded ranking methods might contribute more to this result. Thirdly, each subject's consistency index reached a significant level (p〈. 05). Finally, administration time decreased significantly when the rank order or alternation ranking methods were compared with the paired comparison. We also outlined the superiority of each kind of ranking method in terms of stability, economy, convenience, intuition and applicability.
