While inspecting wind turbines at a wind farm, you collect data on the rotation speed of the blades. Independently, you also measure the wind speed at that same moment. When you graph the data you collected, which variable should be on the horizontal axis and why? In the context of this problem, the wind speed is the independent variable, so it should be on the horizontal axis.
