Unit 6 DB: Experimental Research Methods and Results

Unit 6 DB: Experimental Research Methods and Results

 There are three hallmark features of an experimental study. They are:

  1. Manipulation of the independent variable.
  2. Control groups
  3. Random assignment of participants to groups.
  • Briefly define (in your own words) each of these three hallmark features of an experimental study.
  • Next, explain why each of these hallmark features is important for conducting a valid experimental study.
  • Then, create your own example of an experimental study. How would you apply these hallmark features to your hypothetical experimental study? Be specific. Include a brief statement of what your research results might be.
  • Explain the potential consequences of failing to incorporate these features into your study. Be specific as to how this would relate to your study example and the conclusions you might draw.
  • Finally, describe how you might look at the same research topic by conducting a survey, observation, or a correlational design.
