“…, 42, we obtained the set of grades: . By using fuzzy logic and the associative matrix, we transformed the set of grades into a new set of grades: X = [6,5,5,2,5,4,4,4,4,4,3,4,4,4,4,4,5,3,2,3,4,5,3,4,3,4,2,3,5,5,6,3,5,4,3,5,4,4,6,4,5,4]. We checked if the new set of grades X were statistically different from Y.…”
