  • 2. - Describe & Evaluate the Experimental Researchfollowing research Methods methods: Lab Field Natural -Describe & evaluate each Mr Oakes
  • 3. Write your idea on a post it note and stick onthe board.
  • 4. The research deliberately manipulates theindependent variable (change) whilemaintaining strict control over any othervariable.
  • 5. WeaknessesStrengths  Unnatural situation – Rigorous control over likely to lack validity situation & ppts – can (lack ecological repeat -tested for validity & mudane reliability realism) Controls extraneous  Data lacks depth, variables – few detail – reductionist confounding variables method – by looking at the parts the whole Objective & Scientific might not be studied – (use stats) lacks validity
  • 6. The researcher deliberately manipulates theindependent variable but does this in thesubjects environment
  • 7. Strengths Weaknesses Careful controls –  Control over replicable -tested for extraneous variables reliability is harder than lab exp – possibly more In natural setting - confounding more ecologically valid variables – lack than lab exp validity Less bias from  Ethical issues sampling – subjects don’t have to brought to the lab
  • 8. Cut and sort the statements (there will be oneleft over)
  • 9. The independent variable is changed bynatural occurrence, the researcher justrecords the effect on the dependent variable
  • 10. Strengths Weaknesses IV naturally occuring  Lack of control - Mudane realism & Ecological Validity  No cause and effect as IV not being Research can be directly carried out when manipulated manipulating the IV would usually be  Difficult to repeat – unethical or not cant test reliability practical & generalise
