An educational researcher wants to compare the effectiveness of three different teaching methods for statistics courses in terms of final exam scores. The researcher divides a class of 60 students into three groups, each receiving a different teaching method. At the end of the course, each group has a set of final exam scores. How would you use ANOVA to determine if there's a significant difference in the mean scores among the three groups?
