experimental designs

• What is the first step in the Independent Groups/Measures experimental design?

  Recruit a group of participants
• In the Independent Groups/Measures design, what does each group do?

  Each group does the experimental task with a different level of the independent variable (IV)
• If one group in an Independent Groups/Measures design is set to condition 1 as sober, what is the other group set to?

  Condition 2 as drunk
• How do researchers compare results in the Independent Groups/Measures design?

  By measuring the dependent variable (DV) for each group and comparing the results
• What is the first step in the Repeated Measures experimental design?

  Recruit a group of participants
• In the Repeated Measures design, what do participants do?

  Participants do the experimental task for both conditions of the independent variable (IV)
• What is the purpose of comparing results in the Repeated Measures design?

  To analyze the differences between the two conditions of the IV
• What is counterbalancing in a Repeated Measures design?


  It involves half the group doing condition A first and the other half doing condition B first
• What are the two conditions used in the counterbalancing example?


  Condition A (Sober) and Condition B (Drunk)
• What is the purpose of matched pairs in experimental design?


  To recruit another group that matches relevant characteristics of the first group
• How do researchers treat the experiment in a Matched Pairs design?


  As independent measures
• What is a key advantage of using Repeated Measures design?


  It eliminates participant variables, leading to more valid findings
• What is the main characteristic of Repeated Measures design?


  All participants do both conditions of the independent variable (IV)
• Why is it important to compare results in experimental designs?


  To determine the effect of the independent variable on the dependent variable
