8. To see if a student retention intervention is working we need to compare retention rates of students who got the intervention to those of students who did not across all four years of college. a. Which test do we use? b. Assuming we find a significant difference what can we say about our groups? c. What do we need to do next? d. Complete the source table Source table Source SS df MS F Between 461.643 3 Within 167.419 9 Total e. If our critical value of F is 5.45, is our finding significant? f. What can we conclude from this ANOVA? g. Do we need a post-hoc test? h. What would the post-hoc test tell us?

To test whether students in a higher grade level will be less disruptive in class, a school psychologist records the number of documented interruptions during one day of classes from nine local high schools. The sample consisted of nine (n = 9) freshman, sophomore, junior, and senior high school classes. The data for each high school class are given in the table. (a) Complete the F-table. (Round your answers to two decimal places.) (b) Is it necessary to compute a post hoc test? Explain. (Assume alpha equal to 0.05.) Yes, post hoc analyses are appropriate because the ANOVA is significant. No, post hoc analyses are not appropriate because the ANOVA is not significant.

1. One-way ANOVA review (7pts) a. Why do we need to do post-hoc tests when the F ratio is significant? Would we do a post-hoc test for a non-significant result? b. What does eta squared tell you? c. Consider the following scenario: "Fifteen third-grade students participated in a memory experiment. Five students had a story read to them by a teacher, five read the story themselves, and five saw a video of the story. Each student then took a memory test on 12 items from the story." What is the independent variable (aka, factor) in this scenario? HINT: You may need to come up with a suitable variable name from the description, it is not always explicitly named. d. What is the dependent variable in this scenario? e. What are the levels of the independent variable in this scenario? f. What are the null and the alternative hypotheses in the scenario above? g. What would be the appropriate degrees of freedom in the ANOVA report? In other words, what would be the df1 and df2 in F(df1,df2)?

Exercise 8: ANOVA and PHA Perform the following: A. 1.) Discuss when to use the ANOVA, the One-way ANOVA and the two – way ANOVA. 2.) Discuss the importance of carrying out the post hoc analysis. B. Solve the following problem. Use the extra sheet if necessary. 1.) Consider Ho: μ1=μ2=μ3=μ4=μ5=μ6 a. Complete the following ANOVA table: Source | Sum of Square | Degrees of Freedom | Mean Square | Computed F Treatment | 200 | | | Error | | | | Total | 500 | 30 | b. Using a 5% significance level, would you reject Ho? Perform the 7-steps of hypothesis testing. Use extra sheets, if necessary. 2. In an experiment designed to compare the effects of tutoring on scores obtained on an examination, 3 levels of tutoring were used; none, 4 hours and 12 hours. A random sample of 18 students from a class and each student was randomly assigned to one of the treatment groups. The results of the cores are given in the following table: None | 4 hours | 12 hours 30 | 32 | 35 27 | 30 | 33 26 | 29 | 32 24 | 27 | 30 22 | 25 | 27 20 | 24 | 26 At a level of significance of 0.05, test the null hypothesis that the mean of the three treatment groups do not vary, that is Ho: μ1=μ2=μ3.
