A study was conducted on the effects of long-term marriage (more than 10 years). Researchers gathered data from a random sample

of 4,563 adults and measured quite a few variables, in addition to the explanatory variable of marriage and the response variable of longer life span. According to a newspaper article summarizing the study, those in long-term marriages were more likely to be more physically active, at a healthy weight, and nonsmokers. Those who were not married were about 20% more likely to be deceased. What conclusion can we draw from this study? Explain.
We can infer a cause-and-effect relationship because the sample was selected randomly.

We cannot infer a cause-and-effect relationship because treatments were not assigned randomly.

We cannot infer a cause-and-effect relationship because we do not have a control group.

We can infer a cause-and-effect relationship because multiple variables were included.

We cannot infer a cause-and-effect relationship because the treatments imposed were not blocked correctly.

Response:

The right choice is;

We cannot determine a cause and effect association because several variables were considered

Detailed explanation:

Establishing a cause and effect relationship requires the following criteria;

1) There must be a time sequence where the cause occurs before the effect

The question does not clearly indicate if the divorce (the potential cause) occurred prior to the event

2) If the cause happens, the effect must follow

Thus, everyone who is unmarried should ideally be accounted for to establish a cause and effect relationship

3) The relationship should not be explainable by alternative factors

The query mentions that those who were married tended to be more physically active, maintain a healthy weight, and were non-smokers, all of which contribute to longevity.
