In this study, however, the researchers didn’t do any of this. Why not? More specifically, what was it about the study’s goals that made creating similar groups unnecessary and/or extremely difficult?

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
