I have 2 species of wildflowers. Using scanning electron microscopy. I took images of the petal surface. On the petal surface I measured the height and width of individual cells. I have 1 to 3 individuals per species. I want to compare these measurements between species Are the measurements of cells independent or do I need to use a statistical test to account for the lack of independence? If so, what tests should I consider?
Depends a bit on the nature of your question, but I should think that height and width of cells are going to be highly correlated and both are measures of cell size. I would probably just multiply height by width to get a better approximation for cell area/size, Alternatively you could run a PCA analysis.
