2. Address any confounding variable: It is the one that comes from the outside, the changes resulting due to this variable impart an effect over the independent and dependent variables. This variable can bring change in the outcome of the experiment.  

3. Form a non-falsifiable hypothesis: A non-falsifiable hypothesis refers to the one that can be proved true on the basis of the implementation of suitable methodology and research design.
