Hello, This may seem like a simple question but I am struggling to answer it. I wish to discover if there is statistical significance between three different habitats. I have used a variety of measurements which can be analysed easily, i.e. GLM for height, distance and circumference of trees, GLZ with poisson error distribution for number of saplings. However I am struggling how to analyse canopy cover which was measured on a scale from 0 to 5 (0 equalling no canopy, and 5 equalling total canopy cover). I have run a GLZ with a quasipoisson error distribution, I am unsure if this is correct as it is not technically count data. Any suggestions would be very welcome. Thanks Leah
