Pаrt II (38 pоints): Clаss Size аnd Academic Skills Develоpment (A) 15 pоints: You created a new, categorical version of the class size measure that organized children into three groups: those in small classes that enroll fewer than 16 students (coded 1); medium classes with 16-24 students (coded 2) and large classes with 25 or more students (coded 3). You conducted three ANOVAs using this three-level measure to explore class-size differences in fall and spring literacy achievement as well as the number of books a child has. In describing the post hoc results, use small class sizes as the statistical comparison group. In addition to describing the results of each ANOVA, are there any signs here of a potential link between class size and student learning? What’s the pattern?
