The manager at a local restaurant suspects that the pasta dish served at her restaurant is much more enjoyable than the chicken, beef, and fish dishes. She offers four free entrées to 20 people in exchange for participating in her study. In order to minimize individual differences, she has each participant visit her restaurant four times; she randomly assigns them to have either chicken, beef, fish, or pasta on the first visit, another dish on their second visit, and so on. After each dish, they rate their enjoyment of the meal on a 100-point scale. Here is part of her SPSS output: Is it necessary for her to report effect size, and why?

b. Yes, because we need to know how meaningful the effect of entrée is.
c. No, because the standard deviations are so small.
