how to figure out experimental method
look at IV, DV, environment
lab experiment
RELATES TO THE SETTING
done in a controlled environment where Vs can be controlled
E.G. done in a lab
strengths of lab experiment
high control over EVs
increases interanal validity
more generalisable
limitations of lab experiment
lacks ecological validity
increases demand charcteristics
field experiment
RELATES TO THE SETTING
done in a natural setting where Vs are controlled (EVs less controlled)
E.G. in workplace
strengths of field experiment
limits demadn characteristics
increases ecological validity
weakness of field experiment
more difficult to control EVs
harder to generalise results
reducing external vaildity
natural experiment
RELATES TO THE MANIPULATION OF THE IV
occurs naturally without interventiion but the IV is not directly manipulated but is changed naturally
E.G. effects of natural disater on mental health
strengths of natural experiment
can research variables you cannot manipulate
high in ecological validity
limitations of natural experiment
confounding variables - lacks internal validity
natural experiments are rare
quasi experiment
RELATES TO THE MANIPULATION OF THE IV
researchers are not directly able to manipulate the IV and cannot randomly assign Ps to conditions
E.G. investingating theory of midn with autism vs neurotypicals
strengths of quasi experiment
less bias as the IV is already set
limitations of quasi experiment
difficult to find Ps
