Independent vs. Dependent Variables What is the difference?

Dependent Variable What you are measuring. Helicopter Lab: Measure the time it takes for the rotor to land.

Independent Variable What you are testing or what you are in control of and can manipulate. Helicopter lab: The Rotors that we cut and choose their lengths.

How does the independent variable affect the dependent variable? Way to look at this: How does x affect y? Independent variable is plotted on x-axis. Dependent variable is plotted on y-axis. The Y-axis always depends on the X-axis.

Y and X axis  Y Axis= Dependent  X axis= Independent
