experimental research method

• which two experimental methods have the iv manipulated by the researcher?

  lab and field
• which two experimental methods don't have the iv manipulated by the researcher?

  Quasi and natural
• what are the strengths of a lab experiment?

  high control over variables

  easy to replicate
• what are the weakness of a lab experiment?

  low ecological validity

  demand characteristics

  experimenter effect
• what are the strengths of a field experiment?

  better ecological validity

  less demand characteristic
• what are the weakness of a field experiment?

  less control of extraneous variables

  hard to replicate
• what are the strengths of a nature experiments?

  ecological validity

  fewer demand characteristics

  ethical research
• what are the weakness of natural experiments?

  can't make causal conclusions

  participant variables

  hard to replicate
• what are the strengths of a Quasi experiments?

  higher ecological validity

  enables ethical research where manipulating the iv would be unethical
• weakness of Quasi experiments?

  causal conclusions not possible

  hard to replicate
