4. Types Of Experiment AO3 Flashcards
A strength of lab experiments
Easily replicated - standardised procedure - can be repeated - confirms validity if results match
A weakness of lab experiments
May lack generalisability - controlled environment is artificial- participants aware of being studied - can’t be generalised to everyday - low external validity
A strength of field experiment
Natural setting - researcher goes to participant - IV manipulated- effect of DV recorded
A weakness of field experiment
Ethical issues - may not have given informed consent - invasion of participant privacy
A strength of natural experiments
Only ethical option - may be unethical to manipulate IV - e.g. Studying effects of institutionalisation
A weakness of natural experiments
Event may occur rarely - many natural events are one offs - reduces opportunities for research - may limit scope for generalisability
A strength of Quasi-experiments
High control - often under controlled conditions - shares strengths with lab studies - increased confidence in conclusions
A weakness of Quasi-experiments
Participants not randomly allocated - no control over which condition participants are in - IV is pre-existing - participant variables may have caused change in DV
