DQ1 -Statistical studies are often represented. Summarize in your own words the 10 Guiding Principles from page 720 to help you when reading statistical studies.

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.
