The emphasis during this paper is principally on a replacement measure of correlation coefficient between trapezoidal fuzzy variables, called credibility correlation coefficient, is developed by creating use of the conception of credibility measure. This new measures are found to satisfy sure properties expected value operator and variance of fuzzy variables. The performance of credibility coefficient of correlation is compared with some existing measures of coefficient of correlation for fuzzy variety and therefore the results are mentioned. The man of science makes an attempt to clarify with the assistance of few examples.
Fuzzy variable, Credibility measure, Trapezoidal Fuzzy Variable, Variance of fuzzy variables, Membership function, Credibility distribution and density function
