following questions based on Scenario 1 and data below: Scenario 1: Dr. Merle Haggard compares test performance following study in 3 Music Conditions: Country Music (CW: Oakie From Muskogee), Classic Rock (R: Battle of Evermore), or No Music (NM); 15 college students participate in all 3 conditions. Each participant studied 2 hours and took a different test in each condition. The data are presented below. The researcher wants to Minimize the Probability of Making a Type I Error. Note: M = Mean, SS = Sum of Squares, N = Number in Condition, P = People S CW (X-m) (X-M)2 R (X-m) (X-M)2 NM (X-m) (X-M)2 Mean People 1 90 5 25 88 5 25 86 5 25 88 2 89 4 16 87 4 16 85 4 16 87 3 88 3 9 86 3 9 84 3 9 86 4 87 2 4 85 2 4 83 2 4 85 5 86 1 1 84 1 1 82 1 1 84 6 85 0 0 83 0 0 81 0 0 83 7 84 -1 1 82 -1 1 80 -1 1 82 8 83 -2 4 81 -2 4 76 -5 25 80 9 82 -3 9 80 -3 9 78 -3 9 80 10 81 -4 16 79 -4 16 77 -4 16 79 11 80 -5 25 78 -5 25 79 -2 4 79 12 87 2 4 85 2 4 83 2 4 85 13 83 -2 4 82 -1 1 78 -3 9 81 14 88 3 9 87 4 16 83 2 4 86 15 82 -3 9 78 -5 25 80 -1 1 80 = 85 = 83 = 81 GM= 83 SS= 136 SS= 156 SS= 128 5. if appropriate conduct post-hoc analysis using tukeys HSD. what is the critical value? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 6. if appropriate, what is the value of tukeys HSD for comparing country to classic rock? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 7. if appropriate what is the value of tukeys HSD for comparing country music to no music? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 8. if appropriate, what is the value of tukeys HSD for comparing classic rocks to no music? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 9. adds on the test results of the post-hoc analysis, describe the results in "plain english"? a) test scores are significantly higher after studying to country music as compared to classic rock. b) test scores are significantly higher after studying to country music as compared to no music. c) test scores are significantly higher after listening to classic rock as compared to no music d) there is no difference in test scores for the different music conditions e) both (a) and (b) are correct f) both (a) and (c) are correct g) both (b) and (c) are correct h) alternatives (a),(b), and (c) are all correct i) there is a difference somewhere between the means; however, we do not yet know the location 10. for which of the following pairs would it be appropriate to calculate the confidence intervals? a)country music and rock music b)country music and no music c)classic rock and no music d) both (a) and (b) are correct e) both (a) and (c) are correct f) both (b) and (c) are correct g) all of (a),(b), and (c) are correct h) none of these are correct 11. if appropriate, calculate the 95% interval for the difference between country music and classic rock (note: subtract larger mean minus smaller mean). what is the upper bound value? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 12. if appropriate calculate the 95% confidence interval for the difference between country music and no music (note: subtract larger mean minus smaller mean). what is the lower bound value? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999. 13. if appropriate calculate the biased effect size. what is the value of the biased effect size? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999 14. if appropriate calculate the unbiased effect size. what is the value of the unbiased effect size? note: if appropriate to calculate, round answer to 2 decimal places. if not appropriate to calculate input 999
