Research method: experimental designs Flashcards
Definition of Experimental Method
Either the setting in which the experiment has taken place or the chosen way in which it has been carried out.
Definition of Experimental Designs
The way in which your sample of participants have been allocated to the conditions of an experiment
What are the three types of experimental designs?
Independent Measures
Repeated Measure
Matched pairs
What is the definition of Independent Measures?
Those taking part in condition A don’t take part in condition B
What are the advantages of Independent Measures?
There no order effects such as practice or boredom
You will only need one task for both conditions(standardized)
What are the disadvantages of Independent Measures?
It produces participant/subject variables such as IQ
Quite often you need twice as many partcipants
What is the definition of Repeated Measures?
Those taking part in condition A also take part in condition B.
What are the advantages of Repeated measures?
There will be no subject/participant variables
don’t need as many participants
What are the disadvantages of Repeated Measures?
It produces order effects such as boredom but this can be controlled if the researcher uses counterbalancing.
may need two tasks (not standardized)
What is the definition of matched Pairs?
Those taking part in condition A don’t take part in condition B but participants are matched on relevant participant/subject variables that are important to the study
What are the advantages of Matched Pairs?
No subject/ participant variables
no order effects
may use the same task (standardization)
What are the disadvantages of Matched Pairs?
time consuming
