摘要：

When we deal with crisp data, it is common to find the correlation between variables. In this paper, we propose a method to calculate the correlation coefficient between intuitionistic fuzzy sets, by adopting the concepts from the conventional statistics. The value of the correlation coefficient computed front our formula not only provides us the strength of the relationship of intuitionistic fuzzy sets; but also shows that the intuitionistic fuzzy sets are positively or negatively related. Furthermore, we extend the proposed method to interval-valued intuitionistic fuzzy sets. The value of the correlation coefficient between interval-valued intuitionistic fuzzy sets lies in the interval [-1,1].
