properties
simple scheme of the main types of relationships between the analytical
properties depicted in Fig. 2.1; such relationships can be of the hierarchical,
foundation, complementary or contradictory type.
Figure 2.15 provides a global schematic depiction of the potential relationships among analytical properties. The tetrahedron on the left represents capital
properties; at its vertices are three basic analytical properties. Unfortunately,
representativeness (a capital property) cannot be included as such in this geometric body; however, it is represented as a combination with another capital
property to signify that both determine the quality of the results. The tetrahedron on the right represents the accessory analytical properties, which fall at
its three free vertices and characterize productivity.
I 2.7.1 Hierarchical Relationships
Because quality of the results is the ultimate theoretical expression of analytical
quality, the properties assigned to results (accuracy and representativeness) can
be placed at the top of the analytical hierarchy and referred to as capital
