experimental design Flashcards
1
Q
what is repeated measures design
A
the same pps are used in all conditions in an experiment
2
Q
independent groups design
A
- participants are randomly allocated
- two groups of participants used
3
Q
matched pairs design
A
pre-tests to make people into pairs and one from each pair is put into a different condition
4
Q
strengths of repeated measures
A
individual differences and eliminated and fewer pps are required
5
Q
limitation of repeated measures
A
order effect may take place (e.g. practice, boredom)
6
Q
strength of independent groups
A
- no order effect can occur as pps only take part in one condition
- reduced the chance of demand characteristics
7
Q
limitation of independent groups
A
- participants variables are introduced (controlled by random allocation)
- more participants are required - time consuming to find participants to take part in the trials
8
Q
strength of matched pair
A
- no order effects or demand characteristics
- reduce in individual differences
9
Q
limitations of matched pairs
A
- difficult to match everything about participants
- very time consuming as a pre-test has to be done
