In the hypothesis, "Elderly women receive less aggressive treatment for breast cancer than do younger women," which variable is the dependent variable?

In the given hypothesis, the dependent variable is the outcome that is being measured or affected by another variable, which in this case is age. The phrase "receive less aggressive treatment" indicates that the researchers are examining the level of treatment based on the age of the patients. The degree of treatment received varies depending on whether the patients are elderly women or younger women.

This makes the degree of treatment, which reflects how aggressive or intense the treatment is, the dependent variable because it is expected to demonstrate different outcomes based on the independent variable, which is the age of the patient. The hypothesis suggests a relationship where the age of the patients influences the intensity of their treatment, pointing to the degree of treatment received as the core focus of measurement.
