A relational statement declares that a relationship of some kind exists between or among two or more concepts. Relational statements describe the direction, shape, strength, symmetry, sequencing, probability of occurrence, necessity, and sufficiency of a relationship. The strength of a relationship is the amount of variation explained by the relationship. In regard to shape, most relationships are assumed to be linear. In a linear relationship, the relationship between the two concepts remains consistent regardless of the values of each of the concepts. The relationship can be illustrated by a straight line. Relationships can be curvilinear or some other shape. In a curvilinear relationship, the relationship between the two concepts varies according to the relative values of the concepts. This type of relationship is illustrated by a curved line, as shown in the figure.
