Question

Below is a response from someone how would you respons to this question and please provide a reference please.

By Day 3

Post a brief explanation of when an observed correlation might represent a true relationship between variables and why. Be specific and provide examples

An example of correlation in public health can be found from the relationship between cigarette smoking and lung cancer. According to a study, it was shown that the change over time in the lung cancer death rate of males and females can be explained fairly well by the change in cumulative cigarette consumption (Yamaguchi, Mochizuki-Kobayashi, & Utsunomiya, 2000).

Answer 1

It is well documented in scientific reports that cigarette smoking has extremely harsh effects on our body, and the epigenetic mechanisms of the body are extremely sensitive to the smoke of a cigarette. Many scientific proofs are available which show that smoke of cigarette effect DNA of a person on epigenetic level and which become potential causes of cancer.

What we mean by all this is that in this case, because of all the recorded scientific proofs, we can ascertain ourselves that the relationship between cigarette consumption and lung deterioration is strictly increasing, which means that greater cigaratte consumption is sure to cause more lung problems.

So in such cases where the scientific findings provide us a strong fundamental base, we can be sure that the obtained corrlational findings depict true relationships.
