 abstract={The correlation coefficient (Pearson’s r) is one of the most frequently used tools in statistics. This paper is a continuation of our previous works on a correlation coefficient of Atanassov’s intuitionistic fuzzy sets (A-IFSs).The correlation coefficient we have proposed provides the strength of the relationship between A-IFSs and also shows if the considered sets are positively or negatively correlated. Next, the proposed correlation coefficient takes into account not only the amount of information related to the A-IFS data (expressed by the membership and non-membership values) but also the reliability of the data expressed by a so-called hesitation margin. An analysis of well known benchmark data is provided.},
