Generally speaking, the difference between a Master of Arts, Master of Science, and Master degree is the content and objective of the degree program. Here is a high-level synopsis of each type of degree:
Master of Arts: Focuses on the theory of a subject. Disciplines that do not have a technical application, like English or History, are offered as MA degree programs.
NOTE: CSU-Global does not currently offer any MA Programs
Master of Science: Focuses on the theory and has a stronger base of research in a subject. For example, the Master of Science in Management focuses on the theory (why) by researching the different disciplines of Management.
Master: Focuses primarily on the professional application of a subject. For example, the Master of Finance degree focuses on the how-to of finance rather than the theory behind finance.
