Experimental design Flashcards
What are the three main types of experimental conditions?
Independent group design, Repeated measures design, and matched pairs design
Define independent groups design
Participants are allocated to different conditions. Participants will only experience one condition. The two groups’ data will then be compared.
Define repeated measures design
All participants take part in all conditions. The two sets of data will then be compared for a difference.
Define boredom effects
Boredom and fatigue may cause deterioration in performance in the second condition.
Define practice effects
In a skills-based task, the participants may perform better the second time.
Define counter balancing
Where one group completes condition A first and one group completes condition B first.
Why would we use counter balancing?
It balances out the order effects so that one condition isn’t skewed drastically.
Define matched pairs design
Participants are tested and then matched due to some variable (Intelligence, Sportiness etc). One member of the pair does condition A and one member does condition B.
