Refer to Exercise 11.38 to find the data. Follow the instructions given in Exercise 11.43.
In exercise Sixty-six reading students were randomly assigned to be taught using one of three teaching methods. One method is called Basal and uses textbooks that are organized to develop reading skills. Another method is called DRTA (Directed Reading Thinking Activity) and is a comprehension strategy that guides students in asking questions about a text, making predictions, and then reading to confirm or refute their predictions. The third method, which is called Strat, uses different strategies. The test scores are given in the box. Test the hypothesis that reading method affects test scores using a significance level of 0.05. Show all four steps. Do not do post-hoc tests. Assume Normality.
