  • What are the advantages of an independent groups design?
    It removes order effects
    participants are less likely to work out the aim and change their behaviour/less influenced by demand characteristics.
  • Explain how counterbalancing might improve the design of the study
    addresses the problem of order effects, eg practice, may have occurred in the repeated measures design/because participants took part in both conditions
    by having half the participants do the conditions in a different order any order effects affect both conditions equally.
