### ECOLOGY COURSEWORK STATISTICS HELP!

Hi all,

I am currently working on the stats section of my coursework and all is great except for the explanation of my choice of "infinite degrees of freedom". The weird thing is I was told to do this instead of using the formula, but no one told me why i am using infinite degrees of freedom. My teacher wont even help!! If it helps, my project is comparing the Height/Length ratio of limpets on the upper shore and middle shore. I have 40 data points in one sample and 25 in the other sample. I would appreciate it is somebody can help explain this choice of "INFINITE DEGREES OF FREEDOM".

That is really weird, basically degrees of freedom is the amount of independent comparisons that can be made in your data set. I have only heard of using infinite degrees of freedom in things like quantum mechanics. You are dealing with a finite data set, so that doesnt even make sense what your teacher is doing, all I could guess is that your teacher wants to eliminate the varience and effectively make it zero.
