Therefore, it is also called an ordering diagram. For the Hasse diagram given below; find maximal, minimal, greatest, least, 1. The randomization diagrams and the Hasse diagrams are graphic tools that help to construct the analysis of variance table. %���� data : n x n matrix, which represents partial order of n elements in set.
