DQ2- Ex. 17.16, Find an example of an observational study in the news and answer the following questions. Include a reference to your article.
a. Explain why it fits the definition of an observational study rather than a randomized experiment
b. Describe an explanatory and response variable considered in the study
c. Using the variables in part (b), give an example of a possible confounding variable and explain why it fits the definition of a confounding variable
d. Write two headlines to accompany the study, one that is correct and one that implies a conclusion that is not justified. Explain which is which and why. (You may use the actual headline of the story as one of those).
DQ3 - Ex. S5.1, Visit the websites of one or more professional organizations related to your major. Find one that has a code of ethics. Describe whether the code includes anything about research methods. If not, explain why you think nothing is included. If so, briefly summarize what is included. Include the website address with your answer.
DQ4 - Identify any ethical issues with the way the data for your project was collected or reported. How could the issues, if any, be addressed?
