Abstract Several statistical procedures have been proposed for the analysis of the data from a free sorting task. A straightforward strategy of analysis based on correspondence analysis and cluster analysis performed on the co-occurrence matrix is proposed herein. More specifically, two situations are considered depending on whether the aim is to depict the relationships among the stimuli or to investigate the agreement among the subjects. The approach of analysis is illustrated on the basis of free sorting data characterizing chocolate products.

通过对应和聚类分析对自由排序数据进行统计处理

摘要 已经提出了几种统计程序来分析来自自由排序任务的数据。本文提出了一种基于对共现矩阵执行的对应分析和聚类分析的直接分析策略。更具体地说，根据目的是描绘刺激之间的关系还是调查受试者之间的一致性，考虑两种情况。分析方法基于表征巧克力产品的自由分类数据进行说明。
