Martha is studying the impact that female writers and producers have on the portrayals of television women. She begins the study by doing a content analysis of the credits of prime time television programs and codes for the presence of female writers and producers. In order to determine whether the method of coding for gender using only the names is valid, she takes a subset of the programs, contacts the studio, asks about the gender of the writers and producers, and then compares the results to the results obtained using only the names. This method of testing validity is called:
 
  a. Concurrent validity
  b. Construct validity
  c. Face validity
  d. Predictive validity
