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

I took constant help from HwA for mean, median and mode assignments of random variables and I am very happy with the feedback I get from my professor. The statistics experts at HwA are very helpful and they assisted me to get good grades in all my random variable assignments.

Chris Mathew Student

I must say that the random variable assignment experts here in HwA can surely make the numbers talk. I was given a sheet of data to analyze and honestly I had no clue whatsoever on how to approach. When I came to them they explained me the concept of discrete random variables (as the data was of an outcome of random test on some microorganism) and helped me analyze the same. My teacher at college was very impressed and since then I take help from HwA.

I had few hours to submit my Role of Telecommunications in IT assignment and I was panicking to finish it. But no matter how much effort or research I was not getting the standard that I was aiming for. I put my faith in HelpwithAssignment.com and what can I say its been an amazing journey ever since. The quality of the paper was exactly what my professor was looking for and it has helped improve my grades a lot.

Rubina Ahmed Student

There was a research based assignment on the clinical services available for the aboriginals of New Zealand and for that I needed some expert who knows the nursing industry of New Zealand more than anything else. Luckily here I got hold of one lovely professor who helped me that assignment and many other assignments in the due time.

Sharon Nash Student

From my graduation days in statistics, I took help from HwA on a constant basis. So now that I am pursuing a very challenging certification course in biostatistics I am getting all the help I need from these brilliant experts. The fascinating part about HwA’s biostatistics team is that all the experts are both academically sound and also have adequate professional exposure to work on the critical biostatistics assignments.
