types of experiments

• What are demand characteristics?

  They are cues that influence participants' behavior in a study.
• What is a disadvantage of field experiments?

  They have less control over variables compared to lab experiments.
• What is the main advantage of field experiments?

  They are conducted in natural settings, increasing ecological validity.
• What are natural experiments?

  They study real problems using naturally occurring events.
• What is a disadvantage of natural experiments?

  They cannot establish cause and effect relationships.
• What is mundane realism?

  It refers to how closely an experiment resembles real-life situations.
• What is a key feature of lab experiments?

  They are conducted in controlled environments.
• What is the purpose of lab experiments?

  To investigate the effects of an independent variable.
• What are quasi-experiments?

  They involve naturally occurring independent variables.
• What is a disadvantage of quasi-experiments?

  They cannot establish cause and effect relationships.
• What is a key limitation of quasi-experiments?

  They often study areas that would be unethical to manipulate.
• Why can't quasi-experiments establish cause and effect?

  Because they do not involve random assignment of participants.
