Hi Peter, That's a good question.
mmm ... I'm stepping out of my zone of comfort here, I'm not a statistician or applied mathematician -- so you'll need to check my response with a professional. Your population is small --- so not sure whether sampling techniques are relevant or appropriate in this instance. With a small population like this -- I'm not sure how one one would figure out how your population fits any parametrized distributions. So my uninformed opinion is to go with non-parametric statistics. I could be totally wrong here ;-) Let me ask one or two WikiEducators with better statistical knowledge and point them to your question.
