Question

Suppose you want to study the relationship between smoking and cancer. You assume that smoking is a cause of cancer. Studies have shown that there are many factors affecting this relationship, such as the number of cigarettes or the amount of tobacco smoked every day; the duration of smoking; the age of the smoker; dietary habits; and the amount of exercise undertaken by the individual. All of these factors may affect the extent to which smoking might cause cancer. These variables may either increase or decrease the magnitude of the relationship. Which statement is false

Answer 1

Answer: in the above example, cancer is an independent variable.

Explanation:

Based on the information given, we can infer that the dependent variable is cancer. Cancer is not the independent variable.

The extent to which an individual smokes is.an independent variable, duration of smoking, smoker's age can all be identified as the independent variable.

Cancer is not a independent variable here, in our study cancer is dependent on the amount of smoking by an individual.So, it is a dependent variable.
