whole diagram of types of experiments

2 types of experiments

• true

• quasi

what determines if it is true or quasi

• can the experimenter directly manipulate the IV

• can we randomly allocate p’s to conditions

• yes= true

• no=quasi

true experiment

• can draw causal conclusions

quasi experiment

• cannot draw causal conclusions

2 types of true experiment

• lab

• field

what determines whether it is a lab or field experiment

• what is the setting

lab setting in a true experiment

• controlled setting

• artificial

• contrived (manipulated)

field setting in a true experiment

• takes place in the environment in which the behaviour would typically occur

2 types of quasi experiment

• natural experiment

• dont need to know the other

what determines the side of a quasi experiment

• is the IV comparing before and after

• yes = natural

natural experiment

• levels of IV are naturally occurring and typically have a before and after

• eg mental health of teens in Australia pre and post U16 social media ban

• iv= before and after ban
