    Can easily be repeated.
  3. 3What are the strengths of laboratory experiments? (2)Control - over EV , if all other variables other than IV are controlled successfully or eliminated. cause and effect will be established
    Replication- can easily be carried out again, if the findings are the same then confidence in the experiment goes up
  4. 4What are the weaknesses of laboratory experiments? (2)Loss of ecological validity- high level control over the environment, an experiment can become artificial, results may not generalize to the outside world.
    Demand Characteristics- when participants try to make sense of research situations and act accordingly. natural behavior is affected.
  5. 5Explain the key functions of a field experiment.Naturally occurring surroundings.
    The researcher still has control over the IV.
  6. 6What are the strengths of a field experiment?Improved ecological validity.
    Reduction of demand characteristics.
