- Describe the major differences between a randomized controlled experiment and a quasi-experimentA researcher wants to study about the behaviours of postgraduate students in Australia in mobile phone usage. One of the goals of the study is to analyse whether there is a relationship between the amount of time they spend using the mobile phone and their gender. What are the two variables involved to achieve that goal?With focus group interviews, a) researchers try to select a large sample so that they can extend the results to the whole population. b) the objective is to get the group to interact, so that many ideas are generated. c) it is typical for the researcher to develop quantitative summaries of the results. d) marketing managers can estimate the size of the market for a new product. consumers talk as a group for about 10 minutes and then meet individually with an interviewer.
- A U.S. emergency relief agency is considering sending a team of experts to another country to treat a severely contagious disease outbreak. Each team costs $100,000 for this one-week-long job. The agency estimates effectiveness as follows: 0 teams = 1000 deaths;1 team = 500 deaths;2 teams = 250 deaths,3 teams = 50 deaths;4 teams = 50 deaths Number of Teams Number of Deaths 0 1,000 1 500 2 250 3 50 4 50 If the Agency is considering sending 3 teams vs. 2 teams, what is the marginal cost (in dollar terms) of sending the third team? If saving a life is valued at $200,000 then the optimal number of teams to send is _____.the similarity between the correlation research method and experimental research methodExercise 3.2 A three-man board, composed of A, B, and C, has held hearings on a personnel case involving an officer of the company. This officer was scheduled for promotion but, prior to final action on his promotion, he made a decision that cost the company a good deal of money. The question is whether he should be (1) promoted anyway, (2) denied the promotion, or (3) fired. The board has discussed the matter at length and is unable to reach unanimous agreement. In the course of the discussion it has become clear to all three of them that their separate opinions are as follows: • A considers the officer to have been a victim of bad luck, not bad judgment, and wants to go ahead and promote him but, failing that, would keep him rather than fire him. ⚫ B considers the mistake serious enough to bar promotion altogether; he'd prefer to keep the officer, denying promotion, but would rather fire than promote him. ⚫ C thinks the man ought to be fired but, in terms of personnel policy and…
