    Extraneous variables
    • A. 

      Random error may increase the likelihood of a type II error may reduce power

    • C. 

      The extent to which the manipulation involves the participants in the research

  • 9. 
    Experimenter bias
    • A. 

      When expectations effect the dependent variable

    • B. 

      When participants guess the research hypothesis, to eliminate this cover stories, unrelated experiments, and nonreactive measures can be used

    • C. 

      The experimenter may treat subjects differently because they know what condition they’re in, to avoid this naive or blind experimenters can be used

  • 10.
