Use the scenаriо аnd the meаn table tо answer the fоllowing 6 questions from Items 35 to 40. A researcher is studying the effects of classic children's literature on children's violent behaviors. The researcher selected at random three children's stories from Grimm's fairy tales. He commissioned an author to rewrite each story without the violent references inherent in the original versions. In three treatment groups, the children were read one of the original versions of the tales. In the control groups, the children were read the cleaned up version of the story. A colleague advised the researcher that the age of the children will likely influence their reactions to the story, and that their reactivity will "peak" around the age of 9 years. Sixty 9-year-old elementary school children were selected at random to participate in the study. Ten children were randomly assigned to each group. After the story was read, each child's parents and teachers counted the number of episodes of violent behavior manifested by the child in a 48 hour period. The cell and marginal means computed from the data are outlined in the table below. Question: The dependent variable in this study is the
Use the scenаriо belоw tо аnswer the following 5 questions from Items 29 to 33. A reseаrcher is interested in the difference in attitudinal impact of two teaching methods (A and B), and whether this difference was the same for boys and girls. Students were randomly sampled and independently instructed with one of the two methods and then the attitudes of the students were assessed. Examination of the descriptive statistics showed no serious violation of the assumptions of normality and homogeneity of variances. The means for the groups are shown in the interaction graph below. In addition, the results of a 2X2 ANOVA are tabled below. In a follow up analysis, the researcher opted to use two contrasts to compare the 4 subgroups. The four subgroups were defined in the following order: girls in method A, girls in method B, boys in method A, and boys in method B. The contrast coefficients for the first contrast were 1 -1 0 0 , and the resulting p-value was .007. The contrast coefficients for the second contrast was 0 0 1 -1, and the resulting p-value was .062. Which of the following inferences about the population can be justified based on the analyses that were reported above. Please choose “YES” for the items that are justified and “NO” for the items that are not in the following 5 items. Question: When considering girls, Method A produces higher average attitude scores than Method B.
