    • Laboratory
      highly controlled environment (Lab)
    • Laboratory +
      +Easy to reproduce due to standardised procedure
    • Laboratory
      + Ensures EV aren’t what causes change in DV
    • Laboratory +
      +Easy to estb cause and effect
    • Laboratory -
      -Low external validity due to artificial enviro
    • Laboratory -
      -Demand characteristics (p aware being studied)
    • Laboratory -
      -Bias investigator effects
    • Field
      Everyday environment
    • Field +
      +High ecological validity=natural enviro
      +DC less likely as participants may be unaware of study
    • Field -
      -Less control over EV and so its hard to replicate the study.
      -IV may lack mundane realism
      -Ethical issues
    • Quasi
      IV occurs naturally and hasn’t been determined by researcher e.g. Gender
    • Quasi +
      +Standardised procedure. High controlled
      +Can be generalised to other settings
    • Natural

      IV occurs without the researcher needing to be present (naturally) e.g. earthquake
    • Quasi -
      -Confounding Variables (cant randomly allocate)
      -Hard to prove cause and effect between IV and DV
    • Natural +
      +High ecological and external validity (deals with real-life issues)
      +provides opportunity for research were there are practical/ethical issues
    • Natural -
      -low reliability
      -Cant generalise results
      -Confounding and EV can be present
