Use the statistics for general education and specific statistics for the Business Management field. Look at salaries, job security, wealth creation, the average length of time in career in that field, promotional opportunities, typical corporate titles requiring specific degrees, etc.

With all of this data, do you still want to pursue your major? Will you go for further degrees and when? Internships in your field? Use appropriate citations for the data and facts. Are there professional certifications in your field? Can you pursue these in college? Will you? What is the cost/benefit to doing so?
