Textbook Question
Chapter 9.1, Problem 9.11ACI
Value perceptions of consumers (cont’d). Refer to Exercise 9.10. In addition to the factor, Type of advertisement (within-store price promotion and between-store price promotion), the researchers also investigated the impact of a second factor—Location where ad is read (at home or in the store). About half of the consumers who were assigned to the within-store price promotion read the ad at home, and the other half read the ad in the store. Similarly, about half of the consumers who were assigned to the between-store price promotion read the ad at home, and the other half read the ad in the store. In this second experiment, the goal was to compare the average discount values of the groups of consumers created by combining Type of advertisement with Location.
- a. How many treatments are involved in this experiment?
- b. Identify the treatments.

A factorial experiment was designed to test for any significant differences in the time needed to perform English to foreign language translations with two computerized language translations. Because the type of language translated was also considered a significant factor, translations wwre made both systems for three languages: Spanish, French, and German. Use the following data for translation time in hours.
Spanish. French German

- In a classic study, Shrauger (1972) examined the effect of an audience on performance for two groups of participants: high self-esteem and low self-esteem individuals. The participants in the study were given a problem-solving task with half of the individuals in each group working alone and a half working with an audience. Performance on the problem-solving task was measured for each individual. The results showed that the presence of an audience had little effect on high self-esteem participants but significantly lowered the performance for the low self-esteem participants. a. How many factors does this study have? What are they? b. Describe this study using the notation system that indicates factors and numbers of levels of each factor.arrow_forwardIn this study, the college instructor aims to know whether there are differences in the performance of students among the three classroom environments. We consider the three classroom environments (Mozart’s piece, relaxation music, and silence) as the factor variable. Also, the response variable is the performance of the students which is in the ratio level of measurement. The students were independently and randomly assigned to each of the three classroom environments: Mozart piece, relaxation music, and silence. The p-values obtained from the Shapiro-Wilk test indicate that the assumption of normality was satisfied. Further, results obtained from the Levene’s test indicate that the assumption of homogeneity of variances was satisfied. Considering the variable of interest and the results of the test for the assumptions, the appropriate test procedure to analyze the given data is the Kruskal Wallis Test. The appropriate set of hypotheses to test the given objective is Ho: There is…arrow_forwardW. Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally well when the environment is supportive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do a similar study, conducting a factorial experiment to test the effectiveness of one environmental factor and one physiological factor on a physical health outcome. As the environmental factor, you choose two levels of stressful life events. As the physiological factor, you choose three levels of immune reactivity. The outcome is number of respiratory illnesses in the previous 12 months, and the research participants are kindergartners.arrow_forward
- A research article on the effect of multitasking on grade performance describes an experiment in which 62 undergraduate business students were randomly assigned to one of two experimental groups. Students in one group were asked to listen to a lecture but were told that they were permitted to use cell phones to send text messages during the lecture. Students in the second group listened to the same lecture but were not permitted to send text messages. Afterwards, students in both groups took a quiz on material covered in the lecture.
