Hypothesis:

The more the mileage of a car the lower the used price of the car.

This will be a fair sample because I will pick each one at random so that the test will be fair enough, and in contrast I pick

The results of the calculations will help me compare the Mercedes to the BMW and Ford and also I hope that when I display them I can predict future results but also compare the results to find a viable conclusion.

    Comparing the graphs for mileage All the graphs plotted with mileage against percentage depreciation show a very weak positive correlation. This tells us that as the mileage of car increases, so does the percentage depreciation, which means that the higher the mileage the cheaper the second hand price for a car.
