Research methods

Experimental method (including lab experiments)- research method using random assignment of subjects and the manipulation of variable in order to detemine cause and effect (Example lab experiment)

common way it is designed

  • participants split into two groups
  • one group is the experimental group who are intoduced to a change
  • other group is the control group where no change  introduced to them

Evaluation

Strenghts

  • cause and effect can be determined (deliberate manipulation of one variable while trying to keep all other variables conctant)
  • allows precise control over variables
  • control allows us to conclude the it is the independent variable nothings else influencing the dependent variable
  • experiments can be replicated and if same results found the evidence can support the theory
  • experimental method comsists of standarised procedure and measures which can easily be repeated
