- 1What is the definition of an independent groups design?Individual participants are allocated to do one condition only
- 2Name strengths of using independent groups design?1. Less chance of order effects such as practice or fatigue
2. Can be more time efficient if conditions are run at the same time as each participant only has to perform in one condition
3. More participants are required and thus there is a higher ecological validity - 3Name weaknesses of using independent groups design?1. Because more participants are required, selecting them may be time consuming
2. There may be important individual differences between participants in different conditions not eliminated by the allocation process that may affect the results - 4What is the definition of repeated measures design?Each experiment condition uses the exact same participants
- 5Name strengths of using repeated measures design1. Less time consuming as fewer participants are required
2. No risk of individual differences affecting results between different experimental conditions - 6Name weaknesses of using repeated measures design1. Higher risk of order effects
2. Participants may become aware of intention of study and develop demand characteristics - 7What is the definition of matched pairs design?Separate groups are used but participants are matched together based on similar characteristics such as personality traits, IQ, gender etc
- 8Name strengths of using matched pairs design1. Matching participants as closely as possible on measurable traits may help to control individual differences affecting results
2. Better suited when a repeated measures design won't work due to an order effect occurring which affects the result
3. Less risk of order effects and so counterbalancing is no necessary - 9Name weaknesses of using matched pairs design1. Can be very time consuming
2. Impossible to match people exactly, if individual differences affect the IV rather than the experimental condition then results lack internal validity
3. Because of the difficulty in matching people, sample size is decreased
