A fuzzification is the conversion of an exact quantity to uncertainty. A more generalized fuzzy set called intuitionistic fuzzy set is defuzzified to propose its application in career development to find the homogeneity among students and their career using analysis of variance (ANOVA). The proposed test procedure is well illustrated using a numerical example. The main purpose of this paper is to give a view of intuitionistic fuzzy set with the application of ANOVA technique to emphasize the efficiency in career development. © 2018, Springer Nature Switzerland AG.
