This is an example of the data that I have.
30 plants are a sample. Each plant has been categorized as percentage of green, brown or yellow color (percentages per plant sum to 100). For example:
plant %green %brown %yellow 1 30 30 40 2 50 25 25 3 15 70 15
How can I test if there is a significant difference between categories (green, brown and yellow)?
I have trouble because I think the percentage of each category is dependent on the other.
