Consider a comparative study in which two methods of teaching sight singing to forth graders is studied. Pre- and post-scores for 18 kids in the control group and 18 kids in the treatment group are recorded. Consider the sight singing study. Suppose we wanted to determine if the two methods result in different sight singing success. Suppose the change in post-scores for a unit increment pre-scores was same for both methods. If _{} is the post-score at the - pre-score for the - method, submit the ANOVA table for the appropriate model for the scenario.
