What is an asymmetrical relational statement?
a. As ‘A' changes in value, so does ‘B'; as ‘B' changes in value, so does ‘A'.
b. As ‘A' changes in value, so does ‘B'; as ‘B' changes in value, ‘A' does not.
c. A pair of statements that represents a relationship that is not the same when the order of the variables is reversed.
d. One in which the number of variables is even, not odd.
e. As ‘A' changes in value, so must ‘B' and ‘C'; if both ‘B' and ‘C' change, so must ‘A'; if ‘B' changes and ‘C' does not change, ‘A' may change or remain the same.
ANS: B, C
A symmetrical relationship is complex and contains two statements, such as, if A occurs (or changes), B will occur (or change); if B occurs (or changes), A will occur (or change). In an asymmetrical relationship, if A occurs (or changes), then B will occur (or change), but there may be no indication that if B occurs (or changes), A will occur (or change). As one variable in a symmetrical relational statement changes, the other changes, as well.
