Quizplus · Accepted Answer

Dr. Lewis wants to determine cause and effect relationships between ADHD medication dosages and physical effects in children, which is best done through experimental studies that manipulate the independent variable (medication dosage) and measure the dependent variable (physical effects). Descriptive studies simply describe characteristics or behaviors, longitudinal studies measure changes over time, and correlational studies measure the relationship between variables without manipulating them.
