  1. 1. Wechosethistopic becauseweenjoy movies and werecuriousto seeif one’sgender affected which genrethat person preferred. It issaid that only women enjoy Romantic Comedies(Romance), or “chick flicks”, and men prefer Action-Adventure. Wewanted to test if thiswasan accurateportrayal of gender preferences, or if gender really madeno differencein which genreaperson preferred.
  2. 2. Our population of interest was teenagers aged 14-18, the general high school age. We expected to find that most males chose action films, while most females chose romance. Hypothesis: Ho = Gender has no effect on the type of movie you prefer Ha = Gender has an effect on the type of movie you prefer.
  3. 3.  In our research we found that similar studies have been done before.  Fischoff, in 1994, did a study that revealed film preference to be consistent with gender identity.  Results of the study indicated that the most popular film genres were, in order of rank, drama, comedy, action-adventure, romance, and the combined category of science fiction/fantasy.  Women’s films are not simply “romance” films – they are films in which the story is told from the woman’s point of view, the woman is the clear protagonist or heroine, or the story centers around women and women’s issues.  “Men’s films” tend to focus more on action, sex (rather than romance) and competition.

  4. 4. We gave the following survey to 186 students during the four lunch periods in order to collect data on their gender and movie preferences. 1. Pleasecircle one: Areyou: male female 2. Pleasecircleone: What isyour favoritemoviegenre? Action-adventure Animation Comedy Documentary Foreign Horror Musical Romance ScienceFiction/Fantasy
  5. 5. Genre Male Female Action-adventure 22 (16.83) 7 (12.317) Animation 3 (2.3011) 1 (1.6989) Comedy 63 (56.376) 35 (41.672) Drama 1 (2.8763) 4 (2.1237) Foreign 4 (2.8763) 1 (2.1237) Horror 5 (13.806) 19 (10.194) Musical 2 (1.7258) 1 (1.2742) Romance 0 (5.1774) 9 (3.8226) Science Fiction/Fantasy 7 (5.1774) 2 (3.8226) The numbers in parenthesis are the expected values for that cell. Because no one chose Documentary as their favorite movie genre, we dropped it from our survey.
  6. 6. Genre Male Female Action-adventure 22 (16.683) 7 (12.317) Comedy 63 (56.376) 35 (41.624) Horror 5 (13.806) 19 (10.194) Drama, Foreign, Romance 5 (10.93) 14 (8.0699) Musical, Animation, Science Fiction/Fantasy 12 (9.2043) 4 (6.7957) Thenumber in parenthesisistheexpected valuefor each cell. Dueto our expected cell frequency not meeting thecondition of being greater than five, wehad to combinethecellsthat did not meet therequirement. Wecombined Drama, Foreign, and Romance, and Musical, Animation, and ScienceFiction/Fantasy.
  7. 7. Conditions: Randomization → Simple random sample ☺ 10% Condition → Each population is at least 10 times as larger as it’s sample ☺ Categorical Data → Movie preferences and gender are both categorical ☺ Expected Cell Frequency → > 5 ☺ ∑ − = exp exp)( 2 2obs χ 6.282 =χ P =0.0000093285 Degrees of freedom = 4 P (X2 > 2.86) = 0.0000093285 Significance level = .05
  8. 8. One problem we encountered was the fact that we did not survey enough people, therefore our expected cell frequency was not high enough to run a chi square test. If we were to change something in a follow-up study, we would survey more people to be sure that we had enough. We would also survey classes, instead of in lunch, because the fact that not all students have a lunch could cause a bias. We would also be sure to survey and equal number of males and females to ensure that the data is not skewed towards one gender.
