Question 3 a) Two situations are given below. For each situation, respond to the following research design questions. i. What would be the nature of the study that would be designed - Exploratory, descriptive, or hypothesis-testing? Justify. ii. Would it be a Field study, Lab experiment or Field experiment? Justify. Would it be a causal or correlational study? Justify. iv. Would it be a longitudinal or cross-sectional study? Justify. V. What would be the unit of analysis? Justify. iii. Situation A: The head-nurse in a hospital would like to have a profile of the patients that come to her ward. (10 marks) Situation B: A researcher wants to test the theory that low levels of oxygen in the mines is the single most important factor that make the miners tired easily. (10 marks) c) Develop a theoretical framework for the scenario below: Incidence of smoking in movies has started to increase again, after having declined for several decades. According to the National Cancer Institute smoking is seen in at least three out of four contemporary box-office hits. What's more, identifiable cigarette brands appeared in about one-third of all movies in 2008. Exposure to smoking in movies is an important predictor of adolescent smoking initiation: smoking in movies has been shown to affect adolescents' intentions to start smoking. In turn, the intentions to start smoking are determined by a more positive attitude toward smoking after seeing a film character smoke. Recent research has revealed that the relationship between seeing a film character smoke and the attitude toward smoking is stronger when a person's identification with a film character increases. These findings are consistent with social learning theory, which predicts that attitudes and behaviors are modeled by observing the behaviors of others
