- A researcher wishes to determine if violent television shows increase the tendency of young children to exhibit physical aggression. They have three video shows at their disposal – a cartoon with a high level of physical violence, an episode of Barney, a television show promoting understanding with little or no physical violence or aggression, and a ‘neutral’ show on how corn is grown. Design an experiment to address the researcher’s question using a repeated-measures ANOVA approach.arrow_forwardDiscuss the four assumptions of ANOVA.arrow_forwardJason is applying for an undergraduate business degree oered by the ÜniSA Business School. Jason is preparing for his Graduate Management Admission Test (GMAT). As part of the entry requirements, UniSA Business School species a minimum required score of 38 for the Quantitative component and 43 for Verbal component of the GMAT test, no minimum required score for the Analytical Writing Assessment and Integrated Reasoning. Jason's scores for the Quantitative part of the test are Normally distributed with a mean score of 25:81 and a standard deviation score of 6:79, and scores for the Verbal part of the test are Normally distributed with a mean score of 37:45 and a standard deviation score of 7:11.
