N equals ? (including nifty poll vote)


So, had a little disagreement between me and my sup. I hoped I could get some more opinions on this (hence the nifty poll) :-)

If I presented you a graph of data from a biology investigation on the effect of a certain chemical on the growth of a species of insect (totally hypothetical, but just for example) and I said that for this graph, n=6, how would you interpret this? (Specifically, I mean the 'n=' part).

Turns out me and my sup had different ideas on what this meant and I'd be interested to know others thoughts.
