A statement of purpose is more about telling them the story of you, not a list of specific skills. Schools would like to see a longstanding core interest in solving problems and a penchant for using math and computers to do so. With all the data analytics programs popping up, you should have ample opportunity to find a program which resonates with your personal story, but unlike MBA admissions programs, they won't be quite as picky about your post graduate vision nor your pre-matriculation achievements. If you have a strong GMAT score, a decent transcript and thoughtful reasons for pursuing the degree, you will likely find success in the process if you pick a school which is a good fit. If you are not sure exactly which direction you want to go into, you might spend some time thinking that through before applying. For example, Georgia Tech's new MS in data analytics offers three tracks, one through their college of computing, which is more code-driven for programmers, one through their industrial engineering school which is more about applying tools to solve problems, and one through the Scheller college of business, which is more about how to decide which strategic questions to ask in the first place and how you can use data to solve the right problems in a way which is most applicable to business. Other schools, like Arizona have similar options.
