Independent Groups

• What are the two groups in an independent groups design?

  Experimental group and control group
• What is the purpose of using separate groups in this design?

  To eliminate the order effect in results
• What is an independent groups design?

  It splits participants into different groups.
• How can independent groups design be applied in a tutoring program study?

  • Randomly assign students to:
  • Program group (experimental)
  • Standard tutoring group (control)
  • Ensures fair comparison without exposure to both approaches
• What is the main difference between independent groups design and repeated measures design regarding participant exposure?

  Independent groups design exposes participants to one condition
• What is one advantage of independent groups design?

  No order effects
• What does an independent groups design eliminate?

  It eliminates the order effect.
• Why is independent groups design considered cost-effective?

  It is less time-consuming and cheaper
• What is the main advantage of using an independent groups design?

  It eliminates order effects in testing
• How does independent groups design control individual differences?

  Through random assignment of participants
• Why does independent groups design avoid order effects?

  Each participant experiences only one condition
• How are participants assigned in an independent groups design?

  Participants are assigned randomly to groups
• Why is a larger sample size required in independent groups design?

  To account for individual differences among participants
• How does an independent groups design compare to a repeated measures design?

  Independent groups use separate participants, repeated measures use the same
• Why might independent groups design require more participants?

  Because groups are independent and separate
• How does participant variability impact independent groups design?

  It requires a larger sample size to balance differences
• What makes independent groups design simple to administer?

  It is straightforward to conduct
• What is a limitation of independent groups regarding individual change detection?

  It only compares groups, not individuals
• What do participants in an independent groups design experience?

  Each group experiences only one condition
• What is the order effect?

  A bias from participants experiencing conditions multiple times
• How does an independent groups design ensure participants experience only one condition?

  By assigning them to different groups
• What is an independent groups design?

  A design using separate participant groups
• What is a disadvantage of independent groups design?

  Participant variability can affect results
