In an independent groups experiment, four wines are rated by individuals according to taste preference. The resulting data are shown below. The rating scale is from 1 to 20, with 20 representing the highest possible score. Assume the data preclude use of parametric ANOVA because of assumption violations. Analyze these results using an alternative test.
a. What test will you use?
b. Using a = 0.05, what is your conclusion?
