Regardless of the nuance of the stats though, the idea that you'd choose between wildly differing majors based on watered down averages strikes me as a really poor strategy. The variance on salary progression is huge, and it's not what you learned in school but what you do on the job that fuels your advancement. IMHO you're much better off starting by optimizing what you are naturally interested in at a young age, develop your skills along the way, but stay open and ready for new opportunities as you progress through your career.
