  1. Experiment Design (5)
    • Define research problem
    • formulate research hypothesis which is tested against the null hypothesis (trying to disprove, reject, nullify – usually common view) [alternative hypothesis- researcher's hypothesis]
    • Pretest-Posttest (check if groups are different before the manipulation starts and effects the manipulation; however, sometimes pretests influence effect)
    • Identify control/treatment group
    • Setting: lab or natural?
  2. treatment
    receives the experimental change
  3. control
    does not receive the experiment change
  4. PROS and CONS
    Experimental Design
    • PROS:  the only method that allows us to draw cause-and-effect conclusions. 
    • CON: experimenter bias, difficulty controlling variables, may not generalize to real-life situations (if lab), expensive, time consuming
