experiments

• what is a quantitive method


  uses data that can be counted, usually numerical
• what is a qualitative method 


  data expressed in words

  usually non numerical
• are experiments quantitative or qualitative?


  quantitative
• what is ecological validity?


  The extent to which research findings can be generalized to real-world settings.
• what is the strength of a lab experiment?


  standardised procedures

  extraneous variables are controlled
• what are the weaknesses of lab experiments?


  lacks ecological validity

  research is not reflective of real life situations

  increase in demand characteristics
• what is a field experiment


  studies using experimental design that occur in natural settings
• strengths of field experiments 


  conducted in a natural enviroment which makes it realistic

  ppts are unaware they are being studies which makes it naural
• weaknesses of field experiments


  not all extraneous variables are controlled

  unaware they are being studies which makes it lack consent
• what is a natural experiment?


  experiments that dont change the IV

  its changed naturally
• what is a strength of a natural experiment


  high in validity
• what is a weakness of a natural experiment


  unique characteristics which researchers cant then allocate into conditions
• what is a quasi experiment


  study that is almost an experiment but lacks manipulation of variables
• what is a strength of a quasi experiment


  controlled conditions which means its standardised
• what is a weakness of a quasi experiment?


  cant randomly allocate ppts to conditions meaning co-founding variables are present
