If you are capable of doing statistics/data management for research projects, you will get tons of publications. The analysis you need to do for most papers is actually pretty simple. Setting up all the data and doing some chi squared and Kaplan-Meier tests takes an afternoon after class; people can email you their spreadsheet in the morning and you can send back a full results section, with tables and graphs, that evening.
The problem is learning SPSS is like learning how to use a stove; it won't teach you how to actually cook a good meal. You gotta at least know basic fundamentals of statistics, and for that we're talking a textbook or a college course. It's not hard, but it's a lot of studying you shouldn't be doing now. I could teach you enough SPSS to publish some papers in an afternoon, but without basic knowledge, the analysis you'd produce would be garbage.
My advice: relax and enjoy yourself for now. The risk of burnout in medical school is high, and keep in mind that 2 months off may be the longest time off you'll have for the next 10 years. Go on a trip.
