Q4-For the following data, assuming a within-groups design, determine (calculate): Person One Two Three Four Level 1 of IV 7 16 3 9 Level 2 of IV 15 18 18 13 Level 3 of IV 22 28 26 29 A. dfbetween = Ngroups - 1 B. dfsubjects n-1 C. dfwithin (dfbetween) (df subjects) D. dftotal=dfbetween +dfsubjects + dfwithin - 1 E. SS total (X-GM)2 (GM stands for grand mean) F. SSbetween (MGM)2 (M stands for group mean) = G. SS subjects (Mparticipant - GM) (Mparticipant is the average participant score over the 3 levels) H. SS within SS total - SSbetween - SS subjects I. The rest of the ANOVA table for these data. J. The effect size K. The Tukey HSD statistic for the comparison between Level 1 and Level 3 Q5 Imagine a researcher wanted to assess people's fears of dogs as a function of the size of the dog. He assessed fear among people who indicated they were afraid of dogs, using a 30-point scale from 0 (no fear) to 30 (extreme fear). The researcher exposed each participant to three different dogs, a small dog weighing 20 pounds, a medium dog weighing 55 pounds and a large dog weighing 100 pounds, and assessed the fear level after each exposure. The data table below is the same data from question 4, on which you have already calculated numerous statistics: Person One Two Three Four Small Dog 7 16 3 9 Medium Dog 15 18 18 13 Large Dog 22 28 26 29 A. State the null and research hypotheses. B. Determine whether the assumptions of random selection and order effects were met. C. In question 4 you calculated the effect size for this data. What does this statistic tell us about the effect of size of dog on fear levels? D. In question 4 you calculated a Tukey HSD test for the difference between levels 1 (small dog) and 3 (big dog). What can you conclude about the effect of size of dog on fear levels based on this statistic?
