Identify the independent and dependent variable, control group, and the experimental group Researchers want to know if the gas mileage of cars will increase with a new type of asphalt surface on roads.
independent variable: Type of asphalt on the road Dependent variable: Gas mileage of the cars control group: Cars that drive on the regular, original asphalt experimental group: Cars that drive on the new type of asphalt

dependent variable
the thing that you are measuring in the experiment- you do not control
constants
things that are identical between the experimental group and the control group
objective
unbiased; not subjective
