So I was considering triple majoring (or double or single: I’m in high school) in Computer Science, Mathematics, and Statistics. I have some questions, so feel free to leave your thoughts and answers below. They will be greatly appreciated 
A bit about me: Attending UW Madison in 2015 
Will the three give me a greater advantage when applying to top tier graduate schools for a PhD in one of the three?
Will the three (without a PhD) help me get a job better than two or one? If not, what is best?
If I were to pick two, which two would help me get a job or help me gain entrance to graduate schools?
I am considering multiple majors because of my interests, and also because I have almost 60 credits from high school work, and a 4 year scholarship, so I can take my time.
What do you all think? Thanks again
The three fields are quite related, so I don’t know if triple majoring in those fields gives a huge advantage over a double major. I’ve never heard of someone double-major in mathematics and statistics. Then again, MIT doesn’t have statistics majors, and doesn’t allow triple majoring…
Why, they are very similar. You only need one like Comp Science or Math or the combination of those 2 major.
What are your career plans?
A computer science degree alone will open many doors, and that includes many of the professions dominated by math and statistics majors (apart from academia).
I agree with the above in that computer science and math would be ideal, but really having just a BS in computer science will make you well off if you really make use of it and explore opportunities outside of tech.
Why not try to pursue a combined BS/MS in computer science? I’m not sure if UW Madison has a formal program but it wouldn’t hurt to ask your advisor and see what preparation you’d need. Seeing as you already have 60 credits, you could earn a BS and MS in computer science in 3-4 years, which in my opinion is a much better investment than a triple or double major.
You will likely either get a minor in or come very close to a Math minor if you are a Computer Science major - Most require as much as 20 hours of Math to accompany them (Calc I and II are a given, Discrete Math, Advanced math, Linear Algebra will also likely be there…some require Calc III). If you are going to do Statistics, you might prefer to do the Management Information Systems route as that would lead to roles in Business Intelligence/Analysis. Either way, I’m not convinced you get much of anything out of more than a major in any single one of them.
Meteorology and math is a good idea, but computer science , stats, math they really have the same courses so I don’t know maybe pick two instead of three
