Dear Ecologgers:
I have a data set comparing percent cover in two types of habitat. In both
treatments, I set my protocol such that percentages sum to 100 in each sample,
and then I took the averages and made pie charts to illustrate the difference.
The visual difference between the two pie charts is striking: in one, a single
cover class fills 95% of the pie, and there are only 5 cover classes all
together; in the other, no one cover class is more than 45%, and there are
eight cover classes.
My question: how should I structure these data in order to conduct meaningful
statistical tests? The sample size is (by design) the same in both treatments.
Thanks.
Jason Hernandez
