Suppose we want to find out if a person's gender bears any relationship to his or her favorite genre of movies. 1) We take a sample of people. 2) We classify them by gender. 3) We ask each person to choose a favorite from among action, comedy, drama. 4) We crosstabulate the results. 5) We test for a significant relationship in the sample with a chi-square test of independence. The following data are from: Park, D-J. and Berger, B. K. (2010). Brand placement in movies: The effect of film genre on viewer recognition. Journal of Promotion Management, 16, 428-444. Analysis in R: > freqs = c(39,14,33,10,22,19 ) > movies = array( freqs, dim=c(2,3)) > dimnames (movies) = list (gender=c("female", "male"), + genre=c("action","comedy", "drama")) > movies genre gender action comedy drama 9 female 39 male 1019 10 > chisq.test(movies) Pearson's chi-squared test data: movies X-squared = 6.1862, df = 2, p-value = 0.04536 > chisq.test(movies) $expected genre gender action comedy drama female 36.36496 29.50365 28.13139 male 16.63504 13.49635 12.86861 63504 29.503 dy > chisq.test(movies) $residuals genre gender action lon comedy drama female 0.4369634 0.6436905 -1.156014 male -0.6460628 -0.9517147 1.709200 QUESTIONS (write answers in space provided) 1) What is the null hypothesis for this statistical test?
