Imagine if, in 2012, a researcher at Stanford tested student opinions of instructor competence and discovered that the first woman to achieve the rank of full professor in the materials engineering department was deemed to be "less qualified" if she dressed less professionally after the first four classes but that the same change in attire led to no such decrease in perceived qualification for full professors who were men (rather, they were seen as more approachable but equally competent to when teaching in a continuously professionally dressed (similar) class). I want to follow up on this study at SJSU (but in psychology). Which ONE of the following would not be possible?
a. conceptual replication
b. convergent evidence
c. using focus groups
d. exact replication
