You're on a roll — Patty and Janice's experiment is designed to investigate how wheel size affects the time it takes to go down a ramp. They used two types of skateboards: four with 48-millimeter wheels and four with 60-millimeter wheels. All skateboards were ridden down the same ramp*, which had a constant 30^ angle. They measured the time* it took for each skateboard to go from top to bottom. The experiment's independent variable is the wheel size, and the dependent variable is the time taken. The ramp angle (30^) was a controlled variable. Let's evaluate the given options: *Do skateboards with 60
