- Experimental Designs
- Repeated measures design
- Each ppt takes part in every condition under test.
- +Good control for ppt variables
- +Fewer ppts needed.
- -Order effects, may perform better or worse on each test
- -Ppts may guess purpose of experiment.
- -Condition A may be easier than condition B.
- Independent measures design
- Ppts allocated to two (or more) experimental groups representing different levels of IV.
- +Avoids order effects, ppt only tested once.
- +Avoids ppt guessing aim of experiment.
- -No control of ppt variables
- -Needs more ppts
- Matched participant design
- Ppts who are similar on key variables are paired.
- +Controls for ppt variables because of matching.
- +Avoids order effects, like an independent measures design
- -Very time consuming, matching ppts
- -May not control all ppt variables.
- Repeated measures design
