What does a dependent variable do in an experiment?
It systematically manipulates the independent variable.
It receives the effect caused by the independent variable.
It explains the process through which two variables are related.
It affects the strength and direction of a relationship between variables.
In a study investigating the impact of a new medication on the blood pressure of patients with hypertension, what is the independent variable and the dependent variable, respectively?
Independent variable: Patients with hypertension; Dependent variable: Blood pressure
Independent variable: Treatment group (low-dose, high-dose, placebo); Dependent variable: Medication effectiveness
Independent variable: Blood pressure; Dependent variable: Treatment group (low-dose, high-dose, placebo)
Independent variable: Medication effectiveness; Dependent variable: Patients with hypertension
