Abstract The Randomized Block Designs (RBD) is widely used in agricultural and industrial fields for many decades and uncertainty is usual to all real-life problems, to represent randomness and fuzziness. In such situations the statistical analysis of RBD using fuzzy observations are inevitable. In this paper, it proposes the statistical analysis of RBD through fuzzy ranking method using the location of median value in support of cardinality under Exponential Trapezoidal Fuzzy Numbers (ETZFNs). The numerical examples of the proposed approach would be more precise.
