Experimental psychology uses research experiments to explore human behavior. Conducting these experiments includes all except the following:
  1. Random assignment of participants
  2. Defining variables
  3. Making a hypothesis
  4. Manipulating dependent variables
Explanation
Answer: D - Experimental psychologists perform experiments through use of hypothesis (a proposed explanation), defining variables, randomly assigning research participants, and manipulating independent variables. The dependent variable is never manipulated, as it is what is affected during the experiment, and therefore, fluctuates or changes, based on the independent variables’ manipulation.
