Correlational research is the best choice for examining the relationship between two variables, which in this case are brain damage and intelligence levels. It will allow Professor Milton to determine whether there is a correlation between the two variables as well as the strength and direction of this relationship, without manipulating any variables or causing harm to participants. A case study would only provide information about a single individual and cannot be generalized to the broader population. A survey may not give detailed information about brain damage and intelligence levels needed. Experimental research involves manipulating variables, which may not be ethical or feasible in this case.
