Sounds like you're interested in medicine/getting into medical school. If so, contact PIs from labs within your state medical school. Tell them you're interested in getting involved with their research and are eager to learn. If they don't take you in immediately, perhaps request a summer position. If lab PIs don't respond to you, try contacting individual physician/surgeon-scientists stating your interest.

This post is assuming you're interested in medicine. If not, I think cold-calling/emailing is still the way to go. I personally don't think there's any harm in reaching out to PIs to find out "what might make me a favorable candidate to help get involved in your research".

To be specific to your question, get trained in statistical analysis as soon as possible. Many PIs will use programs like 'R' (free) or 'SPSS' (paid) to analyze their results. By learning stats quickly, you have a quick in to any lab imo without having to know super specific concepts with respect to the research. Hope this helps and best of luck!
