What is the difference between a concurrent relationship and a sequential one, in terms of A and B?
a. In a sequential relationship, A occurs before B; in a concurrent relationship, A occurs independently of B.
b. In a concurrent relationship, causation is clear; in a sequential relationship, causation is unclear.
c. Variable values do not change at the exact same time in a sequential relationship, whereas they change at the exact same time in a concurrent one.
d. Measurement of variables is possible in a sequential relationship, whereas measurement of variables is impossible in a concurrent relationship.
ANS: C
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 amount of time that elapses between one concept and another is stated as the sequential nature of a relationship. If both concepts occur simultaneously, the relationship is concurrent. When there is a change in one concept, there is change in the other at the same time. If one concept changes and the second concept changes later, the relationship is sequential.
