The 20 questions

  1. How many experimental conditions does each participant complete in an independent groups design?

    • Two conditions only
    • Matched conditions
    • All conditions
    • One condition

  2. How many conditions does each participant take part in during a repeated measures design?

    • All conditions
    • One condition only
    • Half the conditions
    • A matched condition

  3. How are participants assigned to conditions in a matched pairs design?

    • Randomly selected
    • Paired by trait
    • Tested in both
    • Self-allocated

  4. A study tests 40 people in one condition and 40 different people in another condition. Which design is this?

    • Independent groups
    • Case study
    • Matched pairs
    • Repeated measures

  5. A study tests the same 30 people before and after a training course. Which design is this?

    • Independent groups
    • Matched pairs
    • Repeated measures
    • Observation study

  6. Which type of variable is controlled by using a repeated measures design?

    • Participant variables
    • Order effects
    • Situational variables
    • Demand characteristics

  7. What is the main weakness of an independent groups design?

    • Order effects
    • Participant variables
    • Fatigue effects
    • Practice effects

  8. What is the main weakness of a repeated measures design?

    • High participant numbers
    • Participant variables
    • Order effects
    • Difficult matching process

  9. Which technique is used to control order effects in a repeated measures design?

    • Random allocation
    • Counterbalancing
    • Participant matching
    • Stratified sampling

  10. What is a major disadvantage of a matched pairs design?

    • Fatigue effects
    • Participant variables
    • Time-consuming
    • Order effects

  11. Which design is best for controlling participant variables when only a small sample is available?

    • Independent groups
    • Case study
    • Opportunity sampling
    • Repeated measures

  12. A researcher randomly assigns participants to two conditions. Which design does this describe?

    • Matched pairs
    • Independent groups
    • Naturalistic observation
    • Repeated measures

  13. A study pairs participants on age and test score, then places one from each pair in each condition. Which design is this?

    • Questionnaire study
    • Repeated measures
    • Matched pairs
    • Independent groups

  14. Why would a researcher choose independent groups over repeated measures?

    • Avoid order effects
    • Match key traits
    • Control participant variables
    • Use fewer participants

  15. Which experimental design requires the largest number of participants?

    • Single participant
    • Repeated measures
    • Case study
    • Independent groups

  16. Testing participants in Condition A then Condition B risks which methodological issue?

    • Sampling bias
    • Ethical issues
    • Order effects
    • Participant variables

  17. How is counterbalancing implemented in a two-condition study?

    • Same condition order
    • Reversing condition order
    • Matching participant traits
    • Random allocation only

  18. In an independent groups design, an uncontrolled difference between groups is called a what?

    • Confounding variable
    • Counterbalance
    • Demand characteristic
    • Order effect

  19. Which experimental design is most likely to be affected by participant fatigue?

    • Matched pairs
    • Independent groups
    • Random allocation
    • Repeated measures

  20. In which experimental design are participants matched on key traits before testing?

    • Matched pairs
    • Repeated measures
    • Random allocation
    • Independent groups
