types of experiment Flashcards
lab experiment
an experiment that takes place in a controlled environment within which the researcher manipulates the IV and records the effect on the DV, whilst maintaining strict control of extraneous variables
field experiment
an experiment that takes place in a natural setting within which the researcher manipulates the IV and records the effect on the DV
natural experiments
an experiment where the change in the IV is not brought about by the researcher but would have happened even if the researcher had not been there
quasi experiment
a study that is almost an experiment but lacks key ingredients.
mundane realism
the same as everyday life/ can be applied to everyday life
lab experiments
strength
High control over CV and EV, high internal validity
lab experiments
limitation
Lacks generalisability, low external validity, demand characteristics, low mundane realism
field experiments
strength
High mundane realism, high external validity
field experiments
limitation
Loss of control over CV EV, ethical issues, cannot consent, invasion of privacy
natural experiments
strength
Provide opportunities for research, high external validity
natural experiments
limitation
Happen very rarely, lack realism, demand characteristics
quasi experiments
strength
Under controlled conditions
quasi experiment
limitation
Confounding variables
