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
