Research Methods

• Operationalisation


  Makes variables measurable, specific and makes replication easier
• Independent variable - the variable that is measured by the researcher 


  Dependent variable - some aspect of the experimental situation that is manipulated by the researcher or changes naturally
• Extraneous variable - any variables other than the IV that may have affected the DV so we cannot be sure of the true source of changes to the DV


  Confounding variables - any variables other than the IV that may have an effect on the DV, if not controlled
• What are the four types of experiment

  Laboratory experiment

  Field experiment

  Natural experiment

  Quasi experiment
• What is the difference between an EV and a CV

  The EV has the potential to impact the DV,whereas the CV does have an impact on the DV
