Experimental Design

• what are the 3 types of experimental designs?


  • independent groups
  • matched pairs
  • repeated measures
• what is the definition of experimental design?


  how the participants were used/organized in the study
• what is an Independent Groups Design


  where participants are in different conditions (numbers of conditions will vary) and they undergo different IVs
• what is a Repeated Measures Design?


  A research design where the same subjects are tested multiple times, and undergo the same IV
• what is a Matched Pairs Design?


  Where participants are placed in pairs based on a pre test for certain variables (factors or characteristics) for the IV.

  Then they are split up into different groups and they undergo different conditions of the IV
• one way to identify an Independent Groups Design?


  Random assignment and more than one condition
• one way to identify a Repeated Measures Design?


  everyone experiences the same IV and there is only one group
• one way to identify a Matched Pairs Design?


  pre-tests were conducted before the experiment for the conditions and the participants are split into different groups
