Professor Sonya was interested in knowing whether a significant difference exist in students' grades whether they sit closer or farther away from the front of the classroom. So, she randomly selected 10 students from your introduction to psychology classroom had them take the first quiz at the front of the classroom, take the 2" quiz at the middle of the classroom, and then take the 3" quiz at the back of the classroom. Each quiz was worth 20 points. Conduct an anova and hds and determine whether students' test scores changed dependent on where they sat in relation to the front of their classrooms?

What is the null and alternate hypothesis (use stat symbols) label each (1 pts) 2. Calculate all necessary sums for calculations (1.5pts) 3. What are critical values for F and HSD at both .05 and .01 levels of the alpha (Ipt) 4. What is the Independent and Dependent Variable - label each (1 pt) 5. Complete the ANOVA summary table. Must label and show calculation for each for credit (6.5 pts) 6. Calculate f (.5 pt) 7. Calculate HDS and d (all 3 of them) (3pts) 8. Write out your interpretations (6 points). Remember to begin with reject or fail to reject null. Tip: about 3 statements for the F and f and about 3 statements for had and d. Don't forget the stat symbols (1 pt) 9. What possible error could you have made: Type I or II error (.5pt) SOURCE 55 of MS F P Rx/factor Error subjects TOTAL
