2. Compare and contrast observational studies with experimental studies.

a. Discuss at least two common issues that can affect the validity of experimental studies. Include an example for each.

b. In part 7 of this assignment, you discussed your poll/survey results. Now that you have had time to reflect on those results, what conclusions can you draw from your study?

c. Are there any confounding factors in your study? (i.e., is there an underlying reason for any surprising results?)

d. Is your poll/survey question(s) appropriate for your hypothesis? (Was there a better way you could have worded the question(s)? Did you ask the “right” question(s)?).

e. Begin to identify the limitations of your study. (Think about your poll/survey tool, sample population, sample size, etc.).

f. It is common for researchers to identify the next steps for their study in a research article. The “next steps” often address the limitations they identified in their study. Based on your work in part 8, identify some next steps for your study.
