Question

Use the following information for the next 6 questions. A researcher wants to compare test performance following one hour of study while listening to each of three great Led Zeppelin songs; Kashmir (K), Black Dog (BD), and and Battle of Evermore (BE). The researcher has 7 participants study a different set of material while listening to each of the three songs and take a test on each of the three sets of material. The data are presented below (high numbers indicate higher test performance). The data are listed below. The researcher wants to maximize the power of this statistical test. Subject K (X - M) (X-M)^2 BD (X - M) (X-M)^2 BE (X - M) (X-M)^2 Mean People 1 82 6 36 80 8 64 78 10 100 80 2 80 4 16 76 4 16 72 4 16 76 3 78 2 4 74 2 4 70 2 4 74 4 76 0 0 72 0 0 68 0 0 72 5 74 -2 4 70 -2 4 66 -2 4 70 6 72 -4 16 68 -4 16 64 -4 16 68 GRAND 7 70 -6 36 64 -8 64 58 -10 100 64 MEAN MEAN 76 0 72 0 68 0 72 SS 112 168 240 N 7 7 7 k 3 Question 24 Scenario 2: If appropriate, what is the value of Tukey’s HSD for comparing Kashmir to Black Dog (Round to two decimal places)? Note: If it is not appropriate to conduct post-hoc analysis, input 999.
