Evaluating Research Findings in Psychology - Chapter Summary and Learning Objectives

Once their research is complete, the researchers must decide if the independent variable actually caused the results of the study. This chapter's well-informed instructors can help you explore whether or not a study's conclusions are valid. Find out the benefits of having a representative sample and the importance of being able to replicate those findings in a different study led by a different group of researchers. Finally, you can learn what happens if the results of a study could be related to chance. By the end of this chapter, you should understand the following concepts:

  • Internal validity
  • Extraneous variable
  • External validity
  • Limits to generalization
  • Replicability and representativeness
  • Causes and meanings of non-significant outcomes
