RESEARCH METHODS - experimental design Flashcards
repeated measures design
Where the same participants are allocated to all groups (i.e. take part in all conditions) of an experiment.
repeated measures design strength
The results will not be subject to participant variables (
repeated measures design weakness
order effects
independent measures design
Where different participants take part in each experimental condition (they will be allocated randomly).
independent measures strength
order effects can’t be observed
independent measures design weakness
participant variables e.g. age, gender
matched pairs design
Where participants take part in only one experimental condition, but they are recruited specifically to be similar in relevant characteristics (
matched pairs design strength
no order effects
matched pairs design weakness
Matching is a more complex process, and it will always be very difficult to match participants identically.
