What are the three types of experimental design?
Independent groups
Repeated measures
Matched pairs
How many groups of participant in independent groups?
2
How many conditions do participants do in independent groups?
1
What are the advantages of independent groups?
no order effects
lower chance of demand characteristics
easier to standardise
How many groups of participant in repeated measures?
1
How many conditions do participants do in repeated measures?
2
How do you control order effects in repeated measures?
counterblancing
What are the disadvantages of independent groups?
Participant variables
more participants
what are the advantages of repeated measures?
control participant variables
higher validity
fewer people required
What are the disadvantages of repeated measures?
order effects
demand characteristics
How many conditions do participants do in matched pairs?
1
How are matched pairs created?
a group of participants is collected, then another group is selected based on characteristics that may effect results
What are the disadvantages of matched pairs?
matching is difficult
cannot necessarily predict which characteristics are important
not perfect control
what are the advantages of matched pairs?
reduces participant variables
no order effects
reduced demand characteristics
