An independent variable in any experiment or research is a variable that is manipulated or changed in the experiment, this change leads to a direct effect on the dependent variable.

A dependent variable is a variable that is directly affected by the independent variable and it is the variable that is measured or tested in an experiment.

Thus,

a. How much gas is left in the gas tank vs. how far the car has traveled.

Independent variable = how far the car has traveled

dependent variable = How much gas is left in the gas tank

b. How much money you've spent vs. how much money is in your wallet.

Independent variable = How much money you've spent

dependent variable = how much money is in your wallet.

c. How far a toy car traveled vs. how much time went by

Independent variable = how much time went by
