    • 2016, Marina Krcmar, David R. Ewoldsen, Ascan Koerner, Communication Science Theory and Research:
      A study that uses only a manipulation is considered a pre-experiment. As the name implies, a pre-experiment has not quite achieved the level of control necessary to be termed an experiment at all.
