Answer: A)
What type of study is Elena conducting?
Elena is conducting an observational study, specifically a prospective cohort study.
How could Elena report her findings in a graph?
Elena could create a scatterplot graph with sun exposure on the x-axis and the incidence of skin cancer on the y-axis. Each point on the graph would represent an individual participant's sun exposure and skin cancer incidence.
What type of statement could Elena make at the conclusion of this study?
Elena could conclude that there is a significant association between high levels of sun exposure and an increased likelihood of developing skin cancer.
B)
What are the ethical issues in this experiment?
There are several ethical issues to consider in Elena's study, including informed consent, privacy, and the potential for harm to participants.
How has Elena accounted for an ethical issue that may have an impact on her participants?
Elena has accounted for the potential harm to participants by providing treatment for any signs of skin cancer that may be discovered during the study. She is also providing information about the dangers of sun exposure and skin cancer at the conclusion of the study.
How could Elena have accounted for an ethical issue that was not clearly addressed by her study?
One ethical issue that was not clearly addressed by Elena's study is the potential for participants to feel uncomfortable or self-conscious during the skin inspections. To account for this issue, Elena could have provided participants with privacy screens or offered the option of having a same-gender inspector. She could also have made efforts to ensure that participants were comfortable with the inspection process before beginning the study.
