Question

A Columbus Dispatch article reported that researchers at the Columbia University Department of Medicine examined records for an incredible 1.75 million patients born between 1900 and 2000 who had been treated at Columbia University Medical Center. Using statistical analysis, the researchers found that for cardiovascular disease, those born in the fall (September through December) were more protected, while those born in winter and spring (January to June) had higher risk. And because so many lives are cut short due to cardiovascular diseases, being born in the autumn was actually associated with living longer than being born in the spring. Is this conclusion the result of an experiment? Why or why not? The conclusion the result of an experiment, since the variable imposed on the patients. What is the explanatory variables? season of birth people who read the Columbus Dispatch article risk for cardiovascular disease and subsequently length of life patients born at Columbia University Medical Center birth year What is response variable? season of birth people who read the Columbus Dispatch article risk for cardiovascular disease and subsequently length of life patients born at Columbia University Medical Center birth year A Columbus Dispatch article reported that researchers at the Columbia University Department of Medicine examined records for an incredible 1.75 million patients born between 1900 and 2000 who had been treated at Columbia University Medical Center.
