Aim

My aim for this investigation is to use given secondary information and to investigate what influences the price of a second hand car.

Hypothesis

Does the engine size of the different cars throughout my data have an effect on the cars price?

Does the age of any car have an effect on the car’s price?

Would the amount of mileage done on specific cars have an effect on their price?

Prediction

Factor 1

I predict that the engine size of the car will have an effect on the cars price because the bigger the engine then the greater the price depreciation will be over a certain period of time.

Factor 2

I also predict that as the mileage increases on the car the second hand price will decrease. Generally as time moves on, the mileage will increase, and the cars with the most mileage will depreciate more in price than the cars with less mileage.

Factor 3

The age of the car I also feel will have an influence on the car’s price, obviously if the car is older the price depreciation will be higher, if the car is newer the price depreciation will be lower.

Plan

Out of 100 cars that were given to me, I’d randomly select 36 cars. I’d select 36 because than later when the pie charts would need to be drawn it would be easier to work out the angles.

There may be a need to research extra ...
