experimental design

• independent group design use different participants in each group
• an advantage of independent group designs is that no one can get better through practice
• a disadvantage of independent group designs is that you have to get more people to participate which might be more difficult
• repeated measures design is when they use the same participants in each condition
• in repeated measures design compares the performances in each condition knowing the differences were not due to participant variables
• an advantage of repeated measures is that a fewer amount of participants are needed
• a disadvantage of repeated measures is that there is the order effect which is when the participants repeat the experiment and might improve due to practice
• matched pair design is when you use different participants in different conditions and they are matched on important variables
• an advantage of match pair is that there is no order effect because there are different people in each condition
• a disadvantage of match pairs is that they need twice as many people to participate
• a disadvantage of match pairs designs is that there are practicalities such as they are time consuming and difficult to find participants that match
