Experimental Methods Flashcards
Lab experiment AO1
Highly controlled environment
Researcher manipulates IV and measures DV
Lab experiment strength AO3?
P-high control over extraneous variables
E-carried out in fake env +aO2
E-cause and effect can be established between IV+ DV
L-increases internal validity
Limitation lab exp AO3
P- lacks eco val
E- carried out in a artificial environment
E- diff to generalise findings of study +ao2
L- lowers external val
Writing frame lab/field
-The experimental method is….
-Bc the iv 1 of 2 is manipulated By researcher to see effects of dv
-And the setting of….. is….
What’s field exp AO1
-natural env (office or park)
-researcher manipulates IV to measure effect of dv
Strength of field exp AO3
P-high eco val
E-based on real life setting
E- easier to generalise findings to similar settings + ao2
L- external val
Limitation of field exp AO3
P- low in reliability
E- environment is natural
E- diff to repeat in same condition
L-won’t get consistent results
Quasi exp method AO1
-IV based On a existing individual diff between ppl
-which the research has not manipulated e.g age
-researcher measures effect of dv
Limitation of quasi exp method AO3
P- sample bias
E-may have unique characteristics
E- diff to generalise to target pop
L- lowering external val
Natural exp method AO1
-researcher takes advantage of naturally occurring IV event
Natural exp method strength AO3
P- high eco val
E- based in real life setting
E- easier to generalise findings beyond setting of study to similar settings
L- increase in external val
Limitation of natural exp AO3
P- low control over extraneous v
E- natural exp takes place in natural env + ao2
E- diff to establish cause and effect of iv and dv
L- lower internal val
