Which degree fields are associated with the highest wages?Which degree fields are associated with the lowest wages? What explainsthis pattern?c. Describe the limitations of your analysis, as well as what additionalinformation would be useful to collect and study in the future. If youcould add one or two variables to your analysis, what would they be andwhy?
