Raymond is completing a study on discrimination in which he has noted that saleswomen who wear skirt suits make more sales than saleswomen who only wear pant suits

However, Raymond determined that his findings only pertained to those industries in which the purchasing decision maker is traditionally masculine. For example, the sales results were the same for all women selling to medical office managers, a female dominated field. Raymond used ________ variables to more accurately explain his results.
A) global
B) general
C) dependent
D) non-reactive
E) contingency

E
Explanation: E) Contingency variables are variables that moderate the relationship between two or more variables. For example, an OB study can say x leads to y, but only under conditions specified in z. Because humans are somewhat unpredictable, all OB studies must have contingency variables. By limiting his results to only male-oriented industries, Raymond is able to make a generalization.
