Finding Feasible Statistical Study Methods
Question
A study is planned to study whether passive smoking (being exposed to secondhand cigarette smoke on a regular basis) leads to higher rates of lung cancer.
a) One possible study is to take a sample of children, randomly select half of them for placement in an environment where they are passive smokers, and place the other half in an environment where they are not exposed to smoke. Then 60 years later the observation is whether each has developed lung cancer. Would this study be an experimental study or an observational study (natural experiment)? Why?
b) For many reasons, including time and ethics, it is not possible to conduct the study in (a). Describe a way that is possible, and indicate whether it would be an experimental or observational (natural experiment) study.
Summary
The question belongs to Statistics and it is about a study on whether passive smoking can lead to high rates of cancer. Two possible ways of study have been suggested and from them, the most feasible method needs to be selected.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
