In correlational designs,a large range in the variable scores is necessary to determine the existence of a relationship.Correlational studies do not involve manipulation of a variable.Providing lengthy descriptions of subjects' behaviors is a necessary part of the discussion of the results,but it does not determine the existence of a relationship.Subjects in correlational studies are not randomly assigned to study groups.
