Experimental design
the different ways in which the testing of participants can be organised in relation to the experimental conditions
1 of 12
Independent groups design
participants are allocated to different groups where each group represents one experimental condition
2 of 12
Positive of independent groups design
no order effects as participants are only tested once
3 of 12
Negative of independent groups desigin
individual differences may account for differences found between conditions
4 of 12
Repeated measures design
all participants take part in all conditions of the experiment
5 of 12
Positives of the repeated measures design
no individual differences as the same participants do all conditions
6 of 12
Negatives of the repeated measures design
increased chance of demand characteristics and order effects
7 of 12
Matched pairs design
pairs of participants are first matched on some variable(s) that may effect the DV. Then one member of the pair is assigned to condition A while the other is assigned to condition B
8 of 12
Positives of the matched pairs design
no order effects as participants only complete one condition and less chance of demand characteristic than in repeated measures
9 of 12
Negatives of the matched pairs design
may not control for all individual differences- very difficult to match participants exactly which may affect the DV
10 of 12
Random allocation
an attempt to control for participant variables in an independent groups design which ensures each participant has the same chance of being in one condition as any other
11 of 12
Counterbalancing
an attempt to control for the effects of order in a repeated measures design; half of the participants experience conditions in one order and the other half in the opposite order
