So I have data regarding the ratio of a cell organelle (the Golgi) to the overall cell size from 48 cells, each one belonging to one of 3 genotypes. I want to investigate whether this ratio is influenced by genotype. My first thought was simply to perform ANOVA on the data (or a Kruskal-Wallis test if ANOVA assumptions not met).
But do I need to be careful with ratio data because this essentially treats two related variables (golgi size and cell size) as a single variable. Are there more suited methods to explore this data?
