Earlier in this chapter we described a study by Bartholow and Anderson (2002) examining how the experience of violence in video games influenced ag- gressive behavior for males and females. Their results suggest that increased violence increase aggressive behavior for males but has little or no effect for fe- males. The following data are measures of aggressive behavior similar to the results obtained in the study. Nonviolent Game Violent Game Female Male 3 6 2 2 4 7 9 9 4 8 10 8 9 4 5 8 4 6 12 16 13 17 13 13 a. Use an ANOVA with a = .05 to evaluate the data. Describe the effect of the violent game compared with a nonviolent game on the aggressive behavior for males and for females. b. Calculate the effect size (n²) for each main effect and for the interaction.Answer correctly please. Give proper explanation. I will rate accordingly
- subject: Quantitative Analysis For Business Please answer both. Use the image for question 10. 10. A hair stylist used market research to learn that members of different age groups have different preferences for positive and negative advertisements. Research participants could mark their preference for only one of the two ads. The positive ad presented a model with attractive hair supported by a message affirming the decision to schedule hair styling services, whereas the negative ad displayed a model with unattractive hair supported by a message describing the need for hair styling services. Results are shown in the table below: What is the probability of a site visitor either preferring negative ads or being a member of age category B? 6% 62% 56% 68% 93% 11. A hair stylist averaged 21 clients per day over the past several months. Typically four of these clients have been male. What is the probability for the total number of female clients the hair stylist can expect…Given the following box plot: 2 Which quartile contains the most data? 3rd quartile 2nd quartile They are all equal. 1st quartile 4th quartile Your answer is incorrect.
