Experimental Designs

• What are the 3 types of experimental design?

  • Independent groups
  • Matched Pairs
  • Repeated measures
• What is independent groups design?


  Experimental design where different participants are assigned to each group.
• What is matched pairs design?


  Experimental design where each participant is matched with another participant who is similar in relevant characteristics, and each pair is randomly assigned to different treatment conditions.
• What is repeated measures design?

  Repeated measures design involves using the same subjects for each treatment condition in an experiment, allowing for within-subject comparisons.
• What is random allocation?


  Random allocation is the process of assigning participants to different groups or conditions in a study randomly, to ensure that each participant has an equal chance of being assigned to any group.
• What is counterbalancing?


  Counterbalancing is a technique used in research to control for the order effects of different conditions by systematically varying the order in which participants experience the conditions.
