Donald is interested in whether blondes, brunettes, and redheads differ with respect to their number of freckles. He randomly samples 60 adults over 60: 20 blondes, 20 brunettes, and 20 redheads, and then he determines how many freckles each subject has. What is the relationship between hair color and number of freckles? What type of ANOVA test do I use?
