SITUATIONSYоu аre wоrking with fаculty frоm Lаmar University's Center for Resiliency on a project that aims to study storm readiness. They are specifically interested in which aspects of communication networks and physical locations lead residents to evacuate in advance of a severe storm. What should you tell them to include in their analysis? In their examination of factors that influence evacuation rates, what factors should they consider other than the content of messages about risk?You are working with a company interested in consumer behavior and your project specifically relates to consumer spending on school supplies (ex. notebooks, children's clothes and shoes, backpacks, etc.). Your company has a large dataset with information on credit card and debit card purchases among American consumers, as well as information about their Facebook posts and social connections through that application. What can this data tell you and your colleagues about time trends in spending on school supplies? Can this data tell you whether people spend more on these supplies during state sales tax holidays (and/or how certain can you be of the conclusions drawn from this data)? What are the strengths and limitations of this data in that regard?You are working with a public policy think tank interested in state-level U.S. health policy. Your organization has a detailed dataset that tracks changes in state cigarette taxes from 1972 to the present day. The dataset also includes the amount of state cigarette tax revenue collected in each county in the years included in the data. What can this data tell you and your colleagues about the effects of state cigarette tax rates on smoking behavior over the last five decades? What additional factors should your organization consider in the analysis if they are trying to examine why smoking rates decline over time, and they decline more quickly in some places than others? How valuable is this dataset to an organization interested in developing policies to discourage smoking?The U.S. Center for Disease Control and Prevention (CDC) compiles data on the causes of Americans' deaths regularly for its Morbidity and Mortality Weekly Report (MMWR). The initial sources of these statistics are local governments, and the CDC compiles and distributes them to develop an approximation of deaths in the country overall. In this scenario, you are working with the Center for Medicare and Medicaid Services to help them develop preventive measures and extend the lives of Medicare and Medicaid patients. Can learning the number of recent deaths from each cause across different regions of the country from MMWR data help you in this task? How central should the examination of causes of death be in developing preventive measures to extend patients' lives? What other information might be needed to develop effective ways to prolong these patients' lives?
