Scis,
Trust me, you do more math in your ER job than you will ever do in many research jobs! Most academically oriented research jobs will have you evaluating and consenting patients, collecting study related data, documenting in a database or on a CRF (case report forms). The statistics involved are complex and generally performed by someone hired by the sponsor or a local statistican. I've never heard of a research nurse who is also responsible for major number crunching!
Research nursing jobs are perfect for organized, detail oriented folks who don't mind a ton of paperwork and who can ensure that a protocol is followed exactly each and every time you see a patient.
Good luck!
