strucLab experiment is..
IV is directly manipulated under controlled setting to measure the impact on a DV
Field experiment is
IV is directly manipulated in natural settings to measure the impact on a DV
Natural experiment is
The CHANGE in an IV is natural and would have occurred without the presence of the researcher (e.g. before and after a natural disaster - no direct manipulation by a researcher) DV is measured
a Quasi experiment is
IV is already occurring (e.g. ethnicity) and so cannot be directly manipulated - the impact on DV is measured
Strength of a lab experiment
controlled conditions increase reliability and internal validity
Weakness of a lab experiment
setting isn’t natural = behaviour isn’t natural and results lack ecological validity
strength of a field experiement
Higher ecological valdity
weakness of a field experiment
lacks control and internal validity
strength of a natural experiment
high external validity, unique study opportunity
weakness of a natural experiment
rare, less likelihood of causality
strength of a quasi experiment
unique insight free from manipulation (less demand characteristics)
weakness of a quasi experiment
cannot randomly allocate - less chance of causality (participant variables)
Naturalistic observation is
conducted in natural settings
Controlled obervation is..
conducted in controlled settings
Covert observation is..
participants are unaware they are being studied
Overt observation is…
participants are aware they are being studied
Participant observation is…
observer is part of the observed group
