Campus administrators want to determine whether eating disorders tend to be prevalent on their campus. They create a particular eating disorders survey scale of 15 items where each item is rated on a Likert scale from 1 (Strongly Disagree) to 5 (Strongly Agree). Higher scores indicate more eating disordered behavior. They collect a large sample of responses to the survey. Administrators hypothesize that varsity athletes will have higher rates of eating disorders than recreational athletes or non-athletes. Which of the following statistics would you use to test their hypothesis?
a. Frequency distributions/histograms
b. One-way ANOVA between
c. One-way ANOVA within
d. Factorial ANOVA
