Elena wants to determine whether sun exposure influences the likelihood of developing skin cancer. The participants in the study will record their exposure to the sun on a scale of 1-5 using an electronic device each day, and Elena will record the amount of sun exposure each person has received over a five-year period. Also, the participants’ skin will be inspected for sunspots and skin cancer both before, during, and after the study. Elena will not intervene to determine how much sun exposure each participant receives. If there are signs of skin cancer at any point during the study, the individual will be provided with treatment, and all of the participants will be given information about the dangers of sun exposure and rates of skin cancer at the conclusion of the study.

1. A) Identify the following factors in Elena’s study of she found that high levels of sun exposure led to higher levels of skin cancer.

*What type of study is Elena conduction? (what kind of study she has to use)

*How could Elena report her findings in a graph? (which graph could she use)

*What type of statement could Elena make at the conclusion of the study?
