Quantitative research methods

Quantitative research methods

1. Lab experiment- an experiment where you control everything on the environment. Pps would not normally be in that environment

   • Advantages
     • easy to replicate
     • can decide where and when
     • high level of control can isolate cause and effect
   • Disadvantages
     • people can be intimidated
     • may be issues in ecological validity

2. Field experiments- an experiment where you have control over the IV but not the general environment. Pps would normally be in that environemnt

   • Advantages
     • less chance of demand charactoristics
   • Disadvantages
     • less control over the environment
     • harder to tell whether the DV is affected by the IV or other variables

3. Natural experiment- where the IV is already changing. so the researcher cannot 'create' a different purpose for the experiment

   • Quasi- where the IV cannot be controlled such as age, gender or ethnicity
   • Advantages
     • allows researchers to investigate behaviours that could not be studied or created otherwise
     • less chance of demand charactorisics
   • Disadvantages
     • less control overall
     • IV is not controlled by the investiagtor
