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 a linear relationship, the relationship between the two concepts remains consistent regardless of the values of each of the concepts. For example, if the value of A increases by 1 point each time the value of B increases by 1 point, the values continue to increase at the same rate whether the value is 2 or 200. The relationship can be illustrated by a straight line, as shown in the figure. In a curvilinear relationship, the relationship between the two concepts varies according to the relative values of the concepts. A negative relationship implies that as one concept changes, the other concept changes in the opposite direction.
